Biofuels: SIAD Macchine Impianti supplies a green hydrogen compressor

March 2022

SIAD Macchine Impianti has produced a hydrogen compressor for a large-scale, multi-megawatt, high-temperature electrolyzer. The contract was requested by Paul Wurth, an engineering company in Luxembourg. The SIADMI compressor will be integrated in the hydrogen processing unit, designed and manufactured by Paul Wurth in the frame of the MULTIPLHY project. Apart from the compressor, the hydrogen processing unit involves a hydrogen dryer as a key element in order to deliver the adequate quality of hydrogen to the end user NESTE, in a reliable way.

The compressor developed by SIADMI is suitable for automatically managing hydrogen at low pressures (0 to 33 bar). The main feature of the unit developed for the project concerns the oil-free compression of hydrogen, which comes from the electrolysis process mixed with varying percentages of water vapor.

In addition, the device has a compact layout with high accessibility. The selection of premium materials also means that it can offer high performance at very low temperatures (down to -25°C). The compressor is designed to follow the variable operation of the electrolyzer, providing outstanding continuity of operation.

Gas Membrane Separators

December 2021

Q-Boss is delighted to announce a new strategic business relationship with a major membrane manufacturer involved in the development and sales of gas separation membrane technology.

Gas Separation Membrane technology is a well-established process technology that is an alternative to conventional solvent-based process technologies. The technology is becoming widely used for the extraction of impurities from gas streams, and for example plays an important role for process clients in the removal of COand H2S

The Gas Separation Membrane process consists of feeding a gas stream to a membrane unit where the gas is exposed to a semi-permeable membrane designed to separate the desirable gases from other components. A pressure differential is kept across the membrane: a high pressure side (retentate or residue) is separated from a low pressure side (permeate) by such semi-permeable membrane. Thanks to the pressure difference across the membrane, the most permeable components will concentrate in the permeate side.

Examples of applications:

  1. Natural Gas Sweetening Product:
    • Wellhead Natural Gas Conditioning (onshore/offshore);
    • Pipeline conditioning;
    • Acid gas removal / Natural Gas Sweetening;
    • Enhanced Oil Recovery (EOR);
    • Biogas / Landfill Gas (LFG) upgrading;
  1. Fuel Gas Conditioning Product:
    • Fuel Gas Conditioning for Gas Engines and Gas Turbines;
    • Volatile Organic Compounds (VOC) removal;
    • Syngas applications.

Decarbonisation, SIAD Macchine Impianti takes on the BOG management for the first liquefied natural gas storage facility in the Italian peninsula.

December 2021

Decarbonisation, SIAD Macchine Impianti takes on the BOG management for the first liquefied natural gas storage facility in the Italian peninsula.

SIAD Macchine Impianti has installed and started up at the Port of Ravenna a re-liquefaction plant for the evaporated natural gas (Boil-off gas – BOG) at the service of the Small Scale LNG (SSLNG) and four cryogenic compression packages (BOG compressors) for the recovery and re-liquefaction of evaporated natural gas again.

The installation is located in a latest generation LNG storage facility owned by Depositi Italiani GNL – DIG.

The storage facility consists of two atmospheric storage tanks for liquefied natural gas (LNG). The LNG is transported by Edison to Ravenna by means of LNG carriers, transferred, and stored in the tanks at the depot and made available for bunkering or to be loaded by tankers and distributed on the mainland at the filling stations.

The storage facility has a capacity of 20,000 cubic meters. Having a potential annual handling of more than 1 million cubic meters of LNG, it will be able to refuel up to 12,000 trucks and up to 48 ferries per year and will therefore be a strategic point for liquefied natural gas refuelling throughout the northern Adriatic for maritime transport and for the central north for land transport. This is a fundamental investment to make the transport sector more sustainable. By using methane as a fuel, emissions of sulphur oxides and particulate matter can be reduced to zero, with a 20% reduction in carbon dioxide emissions compared to traditional fuels.

In this context, SIAD MI has been involved in the compression and re-liquefaction of the BOG. Liquid methane, in fact, during the various transfer operations (from the LNG tanker and during distribution), partly vaporizes and passes from the liquid state to the gaseous state, namely the BOG, which is first compressed and then re-liquefied to be reintroduced into the storage tanks.

The re-liquefaction plant developed by SIAD Macchine Impianti will enable it to treat 1,100 kg per hour of methane, for a total of about 26 tons per day of recondensed gas, thus making it possible to exploit LNG supplies with considerable savings in the long term. Additionally, the green footprint that characterizes the plant is particularly significant: because of the use of methane, in fact, during the life cycle of the plant it is estimated that there will be an overall saving of 6 million tons of CO2 compared to the use of other fuels.

SIAD Macchine Impianti also designed and supplied four BOG compressors, which are oil-free and with ATEX certification for installation in potentially explosive atmospheres. Of these four compressors, two will work at the service of the plant for the re-liquefaction of the evaporated gas and the other two will be involved in managing the gas boil-off during LNG transfer operations from the LNG carrier to the storage facility.

The plant design and construction work by SIAD MI began in August 2019, and was completed in 11 months, perfectly in line with the design requirements, which were met and maintained, notwithstanding the restrictions due to the 2020 health situation. SIAD MI’s work did not end with the delivery, installation, testing, and commissioning of the plant and compressors, but is also continuing with the plant’s operation and remote monitoring, using the latest technology systems.

Commencing in August 2021, a LNG carrier has fuelled the plant with liquefied natural gas, which has enabled the tuning activities to be carried out. The plant entered into operation in October. SIAD Macchine Impianti will continue its commitment at the LNG storage facility, supervising the maintenance and performance evaluation of the BOG compressors and the re-liquefaction plant, thus consolidating a lasting partnership with the Depositi Italiani GNL and contributing to the sustainability of sea and land transport in the Adriatic area.

New ASU supplied in the green energy application

July 2021

Q-Boss is very pleased to advise that SIAD Macchine Impianti has been selected to supply an Air Separation Unit (ASU) to an innovative, low environmental impact, metallurgical complex in Russia.

A large smelter is being built in the city of Vyksa, Nizhny Novgorod Region, Russia, using green technologiesInitiated by the United Metallurgical Company owner Anatoly Sedykh, the project will result in a production facility featuring the best available green technology. With its specifications, the production facility will meet not only current international environment requirements but also future standards aimed at reducing the carbon footprint.

SIAD Mi’s engineers are designing a 17,000 Nm3/h oxygen ASU perfectly in tune with the Carbon-Free philosophy that pervades the entire metallurgical complex project. The ASU plant will be able to produce the three major technical gases (oxygen, nitrogen and argon) in liquid and gaseous form, by separating them from the air.

This project showcases the skills and significant experience of SIAD MI’s engineers in the construction of leading-edge green technology tailor-made plants with international significance.

Snam and SIAD: agreement to develop small-and mid-scale natural gas and biomethane liquefaction plants

May 2021
Snam, one of the world’s leading energy infrastructure operators, and SIAD, a leading chemical group in the production and supply of industrial gases and in the Engineering, Healthcare, LPG and Natural Gas sectors, have signed a framework agreement to start a technological collaboration in the small-scale and mid-scale liquefaction sector. The aim of the agreement is to foster the use of LNG and Bio-LNG as alternative fuels for sustainable mobility and other end uses.

The agreement aims to build small- and medium-sized plants for the liquefaction of natural gas and biomethane on a global scale, on behalf of third-party customers.

The plants proposed by Snam and SIAD will be modular and standardised, with capacities ranging from 50 ktpa (kilo-tonnes per year) to 100 ktpa in the case of small-scale plants and from 200 ktpa upwards for mid-scale plants.

The plants designed by Snam and SIAD use Italian technology, based on an energy-optimised cryogenic nitrogen cycle through the use of two machines (expanders/compressors). These plants allow methane to be transformed from a gas to a liquid state and represent an ideal solution to enable energy transition on global markets thanks to their price competitiveness. The savings compared to a traditional solution can be as much as 30% of the cost of the plant.

As part of the collaboration between Snam and SIAD, a project will be launched in Campania in 2021, with a capacity of 50 ktpa (small-scale), which has already obtained European funding. The plants, which will be operated by Snam, will also ensure the security of LNG and Bio-LNG supply to other regions of Southern Italy, shortening the chain between supply and end users and serving a rapidly growing market. LNG trucks have registered quite an increase in Italy in the last five years from fewer than 100 to about 3,000 units and there are now around 90 filling stations.

Thanks to their versatility, liquefaction plants, in addition to fuelling sustainable mobility, will also be functional for other uses, such as converting power generation from diesel to natural gas and some energy-intensive industrial processes.

Vahterus Cleaning Methods – Keep your process running with our Plate & Shell Heat Exchanger

January 2021
Vahterus Plate & Shell Heat Exchangers are individually designed for each client’s specific application. As part of the design, fouling is taken into consideration, as well as the customer’s knowledge and experience of the process. A correctly designed Plate & Shell heat exchanger has a highly turbulent flow. This turbulence creates a high wall shear stress, which helps to keep the exchanger free from fouling, and most of the 60,000 heat exchangers produced over 30 years at Vahterus have never required cleaning. In rare cases, fouling cannot be avoided, but several Plate & Shell cleaning methods can be used. The method is chosen based on the type of fouling. For the most difficult fouling challenges, Vahterus has developed new methods. Deeper access can be achieved through removable flow director design and the capacity to stretch the plate pack, which opens up the channels for easier cleaning. The fouling product can be removed using a chemical bath, high pressure water cleaning or soda blasting.

Methods for cleaning:
– Back brushing
– Chemical cleaning
– Steam cleaning
– Mechanical cleaning
– Soda blasting
– Pyrolysis
– Ultrasonic cleaning

Liquefied Biomethane is a reality in Italy thanks to The SIAD Group working with Vulcangas and Iveco

December 2020
Italy starts the production of biomethane. In the last few days, in the province of Lodi, work on the first agricultural LNG production plant has been completed.

The project has brought together companies from an all-Italian supply chain: the SIAD Group, a chemical company specialising in the production and supply of gas; Vulcangas, a company that distributes LPG for both domestic and automotive use; Iveco, a manufacturer of industrial vehicles; and Lucra 96, a farm in the province of Lodi where the innovative plant is located. It is all the result of a year’s work, now able to produce up to 3 tons of liquid biomethane per day.

By sharing its consolidated know-how in the technical and natural gas sector, in addition to the drive for innovation in the engineering field, SIAD has ensured a significant contribution through its Group companies: Tecno Project Industriale has developed the biogas purification unit (upgrading), while SIAD Macchine Impianti has developed the system for transforming biomethane from gaseous to liquid state, a fundamental step for its distribution ; finally, SIAD Spa manages the supply of nitrogen which is essential in the liquefaction process.

The supply chain, 100% “made in Italy”, is all part of CIB, the Italian Biogas Consortium: each subject, by pooling experience and expertise in its specific sector, has worked in synergy, with the shared objective of creating a project that will give a strong boost to the decarbonisation of transport, promoting the transition from an economy based on the use of fossil fuels to a more sustainable one, all in line with European Green Deal policies.

Biomethane, produced by anaerobic digestion of biomass, is similar in composition to methane. Used mainly in road transport, it can ensure a high reduction of CO2 emissions into the atmosphere compared with fossil methane.

This first plant is therefore of great strategic value and represents a further endorsement of a virtuous circle: Italy, relying on internal production of biomethane, which is less subject to sudden supply interruptions, will be able to start offering company fleet vehicles an alternative to importing from abroad. A more sustainable solution, also economically.

Vahterus – Plate and Shell Heat Exchanger: LNG in the spotlight

June 2020
Our customers are changing energy source from heavy fuel oil to Liquefied Natural Gas (LNG), which is becoming an increasingly popular fuel in marine and onshore applications and in power generation.

The rich possibilities offered by LNG have encouraged our partner to undertake extensive R&D work to understand the special features of heat transfer with cryogenic fluids. For an engineer, it’s always exciting to see the extremes, for example in temperatures, like using liquid nitrogen at temperatures of -180°C to test our heat exchangers in an environment that’s equal to LNG vaporising conditions.

In these conditions, the materials, the welding quality, as well as heat-transfer efficiency of our exchangers are rigorously tested. That has been our focus this spring. In this special issue, you can read about a larger series of cryogenic experiments in our Test Lab and about FEM simulations that help us to continuously improve the constructions used in the cryogenic environment.

Green Energy “Made in Italy”

April 2020
Italy’s first liquefied natural gas (LNG) coastal depot, built by Depositi Italiani GNL S.p.A., will become operational in 2021. Located in the Port of Ravenna, the depot represents an outstanding opportunity for Italy, a new source of supply of LNG (Liquefied Natural Gas), essential to reach the country’s greenhouse gas emission reduction targets, especially in the heavy-duty and maritime transport sectors.

The facility will have a capacity of 20,000 cubic meters of LNG and an annual handling capacity of more than 1 million cubic meters of LNG, which will be used as alternative sustainable fuel in the heavy-duty and maritime transport sectors: the facility’s capacity will enable it to handle enough LNG to supply at least 12,000 trucks and approximately 50 ferries every year. It is estimated that during the life cycle of this project, which is expected to start operating in the second half of 2021, it will prevent the production of 6 million tons of CO2.

SIAD MI was chosen to design and install a SMART LNG system to re-liquefy evaporated gas (Boil-Off-Gas – BOG) from the tanks of the coastal depot. Once reconverted into a liquid state through a nitrogen recycling refrigeration system, the retrieved gas will be re-introduced into the depot’s tanks, with zero emissions into the atmosphere, through a closed circuit that has no impact on the environment.

SIAD MI is also involved in the provision of cryogenic compressor packages – BOG compressors – to be installed to manage the Boil-Off-Gas during the unloading stages of LNG cargo ships, when LNG is transferred from the ships’ storage tanks to the depot’s tanks.

Thanks to the wide experience and know-how gathered in cryogenic technologies, SIAD Macchine Impianti has developed a wide range of natural gas liquefaction plant.

SMART LNG plant are the first solution developed in Italy for the liquefaction of natural gas (LNG) on a small and scale.

The gas produced in this way can be used locally in transport service stations or for micro-distribution networks. SIAD Macchine Impianti uses tested and proven technologies characterized by easy plant start up, operation and shutdown, but also involving highly reliable and efficient nitrogen-handling machines (turbines and compressors).

The plant is also performing with high-pressure, natural gas network and its liquefaction process is flexible, so that a variation in capacity is straightforward and continuous operation is possible.

All this without sacrifying safety, by using nitrogen (inert gas) instead of hydrocarbon as a refrigerant.

Penta is celebrating 40 years of successful operations in the Metal Seated Ball Valves Market

August 2017

Penta’s historical journey shines a light on our past, present and future.

Our journey begins with the development of the first metal seated valve for extreme working temperatures (up to 720°C), to the challenge of managing low temperature services (down to -196°C), and to the development of models for abrasive services and Multiport valves (3 ways).

Penta’s latest industry-leading development is an innovative Wafer Split Body Design, as the starting point for the development of soft seated ball valves, which are designed to make the maintenance on those wafer valves used on dirty services easier. The use of a spit body wafer design eliminates the possibility of galling on the end ring nut. The automatic body cavity pressure relief, together with bi-directionality, make this model technically superior.

With over 40 years of experience in the ball valves industry, Penta products are synonymous with quality and reliability, thanks to the continuous investment in Research and Development into unique technology solutions in the industry, entirely made in Italy, that meet the specific needs of our customers.

PSHE for high-pressure geothermal power generation application

Septemeber 2016

In 2011, Queensland Geothermal Energy Centre of Excellence (QGECE) in Australia was looking for compact and robust heat exchanger solution for a lab environment geothermal power generation system. The Queensland Geothermal Energy Centre of Excellence was established in 2009 in Pinjarra Hills, Brisbane, Australia. The purpose of the research centre was to assist the uptake of geothermal power generation.

Vahterus and Q-boss worked closely for this project. “They were successful in obtaining the contract after an internal review process. A key aspect of the review was the ability to provide compact, cost-effective, high-pressure heat exchangers suitable for the required duty. During the tendering and supply process Vahterus and Q-Boss were very supportive, and provided assistance and information as required. In operation, the heat exchanger units have performed as required,” says a QGECE Research Officer.
The fully welded structure and the compact size of Vahterus PSHE proved to be a winning combination: it utilizes the thermal capabilities of corrugated plate technology and housing the platepack with a pressure vessel (shell) to create an innovative and robust heat exchanger solution.

As an end result of the close cooperation between Vahterus, Q-boss, and the customer, the units were successfully put into operation. More recently, the system had a piping upgrade, the team worked effectively again to allow the upgrade to proceed rapidly.

SIAD Macchine Impianti Global Service Division: new life for compressors

May 2016

Continuous optimization of compressors. With the new revamping tools, “Revamp Conversion” and “Modernization”, the aim is to upgrade outdated technologies, renew worn machines and replace old-design components. This gives a significant reduction in machine downtime, better performance at equivalent consumption plus operating conditions in maximum safety, always in compliance with current regulations.

The main advantages of the revamping include the upgrading of the machinery to the new process or capacity conditions; a guarantee is then issued, attesting that the examined compressor is as new.

SIAD Macchine Impianti Smart Liquid Plant

April 2016
