Title: Cooling medium
Inventor: KANAO MITSUHIRO
IPC: C09K15/32
Filed: 1992-06-10
Abstract: PURPOSE:To avoid the ozone layer depletion due to a CFC cooling medium by using a cooling medium which comprises a mixture of an org. compd. with a silicone as a flame retardant, is heavier than the CFC cooling medium, and does not reach the ozone layer. CONSTITUTION:A mixture of an org. compd. with a silicone as a flame retardant is used as a cooling medium. Having a high viscosity, the silicone is pref. used as a soln. in LPG. which has higher volatility, capacity as a cooling medium, and dissolving power than the silicone. Although LPG is a very ignitable fuel, its mixture with a silicone significantly loses the ignitability since Si atoms and OH groups of the silicone have fire-extinguishing capabilities.

Abstract: PURPOSE:To recover not only a solvent having a high b.p. and easy to decompose but also a solvent diffused into air in low concn. with high quality and high efficiency by combining a concn. part concentrating solvent-containing gas to be treated in high concn. with a low temp. condensing recovery device recovering a solvent by condensation or freezing. CONSTITUTION:Gas to be treated is passed through the treatment zone 1a of a rotor 1 composed of an activated carbon honeycomb molded object to make the solvent in said gas adsorbed. The solvent adsorbed on the rotor 1 is desorbed by regenerating gas and this solvent conc. gas is sent to condensing towers 2, 3.
