Small scale liquefaction plants open new market opportunities for the development of local or regional gas distribution networks, where gases did not previously exist as an alternative environmentally friendly and competitive energy source. Small scale LNG is also highly interesting as a price competitive and environmentally friendly fuel for ships, trucks and general industry. Cost and energy efficient small scale LNG plants also open possibilities to monetize previously stranded gas sources.
Gas sources can typically be pipeline gas, well gas or flare gas.
Such gases need to be cleaned to achieve low contents of water (1 ppm), CO2 (<50 ppm) and H2S (< 4ppm). Gas cleaning systems can also be delivered by Wärtsilä upon request.
The Kollsnes II plant (below) located near Bergen, Norway features a complete LNG plant scope including a total gas cleaning system.
