processes. Membrane technology is becoming more important for
CO2 separation from natural gas. This is due to advantages such
as operational simplicity, high reliability, low capital and operating
cost, environmentally friendly, good weight and space
efficiency along with reduced energy consumption (Dortmundt
and Doshi, 1999). CO2 membrane technology of UOP–LLC was
adopted in this study (Dortmundt and Doshi, 1999). The
membrane set up was connected with compressor booster.
Compressed gas was passed through the compressor booster; it
containing ground storage pressure of 250 bar and a flow rate
of 330 m3
/h. The control system and addition of CBG (CBG decant
panel) was monitored continuously by PLC (Programmable Logic
Controller). The system performance quality and compressed gas
cylinders were evaluated. Gas samples were collected and analyzed.
Gas improvement before and after purification yields are
listed in Table 2
