Techno-economics and sensitivity analysis of hybrid

Aug 01, 2021 The conceptual designs of a carbon molecular sieve (CMS) membrane and a distillation process with heat pump integration were used to evaluate propylene/propane separation system economics. A CMS membrane prepared on a porous alumina hollow fiber was employed to establish the conceptual design of the integrated system.

Hello Everyone,In the past I distilled TEA from calcium hydride. There is generally a yellow color in the distillant pot. My question concerns the best choice of molecular sieve to use to store the fractions after distillation. Perrins book mentions 4 . I read Williams and Lawtons paper, and I scanned several of the series of papers by Burfield and colleagues, but I did not see TEA …

How not to kill the molecular sieve

Jun 13, 2017 A three-angstrom (3A) molecular sieve, such as the EthaDry offered by Hengye Inc., is specifically designed to dehydrate ethanol, with crystal pore openings measuring about three angstroms in diameter. This sieve is ideal for ethanol production because water molecules measure about 2.8 angstroms, while ethanol molecules are about 3.6 angstroms.

molecular sieve chemistry Britannica

molecular sieve, a porous solid, usually a synthetic or a natural zeolite, that separates particles of molecular dimension. Zeolites are hydrated metal aluminosilicate compounds with well-defined crystalline structures. The silicate and aluminate groupings form three-dimensional crystal lattices surrounding cavities in which the metal ions and the water molecules are loosely held.
