MR-PEGAZ TECHNOLOGY FOR EFFICIENT LNG PRODUCTION

One of the high-potential technologies developed by PEGAZ is an MR-PEGAZ natural gas liquefaction technology with the use of a mixed refrigerant with trigeneration pre-cooling of process flows.

 

 

MIXED REFRIGERANT WITH TRIGENERATION PRE-COOLING OF PROCESS FLOWS

 

 

1 – booster compressor, 2 – BOG compressor, 3 – recycle compressor, 4 – treatment and dehydration unit, 5 – compressor drive, 6 – absorption refrigeration machine, 7, 8 – water coolers, 9, 10 – waste heat exchangers, 11 – LNG separator, 12-14 – reducing devices
