PROPANE AND PROPYLENE SEPARATION FROM GAS MIXTURESpropane and propylene separation from gas mixturesPAUL FEILER
In this work we report new experimental data of pure and binary adsorption equilibrium of propane and propylene on zeolite 4A at 423 and 473 K. The pressure range studied was 0–500 kPa, which is the entire pressure range used in PSA–VSA (Pressure–Vacuum Swing Adsorption) units. The amou...
99.5%) and propane (purity > 99.9%) were purchased from KODI Gas Chemical Industry Co. Ltd. (Foshan, China). Fabrication of LGO, rGO and nanoporous rGO nanosheets. In this case, GO colloidal solution (0.1 g in 150 mL deionized water) was obtained using a ...
Solution: C3 components in waste gas were absorbed by butyl aldehyde blend as an absorbent. Then, rich absorbent was desorbed to recover C3 components, which were separated by using ADV® valve trays to get propane and propylene products. The whole process was simulated by ZEHUA. ZEHUA also ...

Isopropanolamine is alkaline, being able to absorb acidic gas, widely used in gas purification such as the desulfurization of synthetic ammonia industry and decarbonation. Propylene oxide is mainly used in the production of propylene glycol, polyether polyols, polypropylene glycol, propylene glycol ...

However, this increases the difficulty of defect-free membrane growth, and only a few MOF materials (statistically in which ZIF-8 is predominant) have been successfully grown for gas separation28,29,30. Therefore, the combination of grain boundary elimination and a robust ZIF-67 membrane ...
