Mid-scale LNG Plant Processes and Equipment

(>0.25 to <2.0 MTPA)

Mid-scale LNG plants provide a means to serve LNG niche markets, to monetize smaller gas volumes at reduced ownership cost, and to allow for staged investment of large LNG facilities.  Air Products meets the need for mid-scale LNG plants with proprietary liquefaction processes and equipment for simplicity while delivering lower unit costs.
