Fantastic news! We've Found the answer you've been seeking!
Question:
(a) percent recovery of methane in the retentate stream [90.1%]
(b) area of the membrane, ft2, assuming both a linear and log-mean driving force. How do these two approximations compare to the actual area of 33,295 ft2?
(c) permeance of CH4 ft3(STP)/(ft2·hr·psi) and the selectivity of the membrane, a12. [a12 = 19.3]
Note: MSCFD = 106 ft3(STP)/day
