Saipem presents a new technology for application to the LNG market
Saipem’s latest technological solution for application to the LNG market, known as LiqueflexTM, was presented the at the latest GASTECH, the most important international conference dedicated to the natural gas and LNG industry recently held in Houston, Texas. With patent pending, LiqueflexTM is targeted at the small and medium scale natural gas liquefaction market, such as the local distribution of LNG.
LiqueflexTM technology consists of a process of liquefaction of natural gas applied to LNG plants conceived according to a standardised design which can be installed on a modular basis with a productive capacity ranging from 200,000 to 1,200,000 tonnes per year. These features facilitate the curtailing of costs and assembly times. Since it does not require the use of hydrocarbon liquid refrigerants, the new liquefaction technology reduces the risks associated with safety problems. This compact plant engineering solution is adaptable to variations in the composition of natural gas and is particularly suitable for installation in congested industrial areas and on floating and offshore facilities.
For onshore applications, LiqueflexTM has been designed for application in ports which have a nearby natural gas pipeline from which the pre-treated gas can be drawn. The system can also be used as a small hub that both produces and distributes LNG through filling stations for vessels and truck loading facilities for land transport. Diffusion of such an integrated system would also allow for significant reductions in investments in maritime infrastructures for the docking of large-size LNG transport vessels and associated permit costs.
Eric Zielinski, Saipem’s Upstream&LNG Product Manager, explains:
“The design of LiqueflexTM emerged from the need to adopt strategies that reduce the environmental impact associated with sea and road transport and to enable the development of alternatives to traditional liquid fuels. Indeed, the replacement of petrol and diesel with LNG is a strategy promoted by the authorities and by energy companies the world over, particularly in those areas where infrastructures have not been developed, or have been developed only partially, and where the lack of LNG supply is keenly felt”.
