Title
(EN) PROCESS FOR DRYING A GAS STREAM COMPRISING A FLUOROPROPENE
(FR) PROCÉDÉ DE SÉCHAGE D'UN FLUX GAZEUX COMPRENANT UN FLUOROPROPÈNE
Abstract
(EN)
A method of drying a fluid comprising a fluoropropene, which method comprises the step of contacting the fluid with a desiccant comprising molecular sieve having openings which have a size across their largest dimension of from about 3 Å to about 5 Å. A heat transfer device comprising a heat transfer fluid comprising a fluoropropene, and a desiccant comprising a molecular sieve having openings which have a size across their largest dimension of from about 3 Å to about 5 Å. Preferably, the fluoropropene is R134yf or R-1225ye.
