WebJul 11, 2024 · The conversion factor (CF) is used as follows: conventional unit × CF = SI unit. SI unit ÷ CF = conventional unit. What is GPU permeability? Permeance is also often expressed in gas permeation units (GPU), where 1 GPU = 10 − 6 cm 3 (STP)/(cm 2 s cm Hg). In the SI system the unit of permeance is mol/(m 2 s Pa). How do you conjugate … Web) permeance of 4,000 gas permeation units (GPU) with mixed - gas CO. 2 /nitrogen ( N. 2) selectivity of 25, and (2) CO. 2. permeance of 3,000 GPU with mixed-gas selectivity of 50. The first type will be used in the CO. 2. removal step and the second type will be used in the CO. 2. sweep step, both of which are parts of MTR’s innovative post ...
