Gas separation with fractional purge for pre- or post-purification |
摘要 |
<p>Gas separation membrane operations are carried out with gas being withdrawn from a portion of the membrane modules for use as purge gas in upstream or downstream purification or drying operations. The gas, either permeate or non-permeate from the remaining modules is separately withdrawn from the system. Power and membrane surface area requirements are desirably decreased thereby. <MATH></p> |
