WebJul 26, 2024 · Two CO 2 -philic polymers, polyethylenimine (PEI) and poly (ethylene glycol)-bis-amine (PEGBA), were evaluated. The separation performance was characterized … WebSep 18, 2024 · It is given in units of m/s. Consequently, the permeability coefficient gives us an idea of the velocity with which a given substance will permeate a given membrane. What is the unit of permeation? Permeance is also often expressed in gas permeation units (GPU), where 1 GPU = 10 − 6 cm 3 (STP)/(cm 2 s cm Hg). WebThe intrinsic permeation property of a gas through a membrane is characterized by the permeability coefficient P of a gas A, P A. …. Permeance is an important parameter when comparing the separation suitability of membranes for mixed gases. A practical unit often used is GPU (gas permeation unit) (see below). british liver trust love your liver roadshow
