LPG
In the late 1970s,SASPG entered the field of natural gas separation (LPG)
Successfully developed natural gas liquefaction units of 50,000, 100,000, 300,000, 600,000, 1 million, 2 million, and 5 million cubic meters.
The MRC mixed cooling process technology of "two-stage throttling and three-stage separation + heavy hydrocarbon washing" has been successfully developed, which saves energy and reduces consumption and is reliable in operation.
The process technology of producing LNG by cryogenic rectification has been successfully developed from gas sources with low methane content (such as coke oven tail gas, chemical purge gas, etc.).
SASPG has its own patented liquefaction technology: sas-lique
A small skid-mounted LNG unit has been developed for wellhead gas, with a highly integrated modular design, short supply cycle, and small on-site installation workload.
