Recovery of anesthetic gas

摘要

To separate and recover gases of different vapor pressures, from a gas mixture, the gas components are bonded in adsorbent zeolites at a temperature level above a temperature specific to the material. The zeolites are enriched with Si, with a Si/Al ratio /-180 and with a pore diameter of 0.7 nm. The zeolite has a hydrophobic and organophilic character. The pores and hollow zones have only a small or no electrostatic field. It has a unified pore diameter through synthesis or modification to match the molecular diameter of the gas to be adsorbed, or be slightly larger. An Independent claim is included for an apparatus with an adsorber (1) to collect the emitted gases, linked to a chemical vacuum pump (9) through a channel (3) and valves (4,7). The pump, using an underpressure and heat from a heater (2), draws the gas into a condenser (13) chilled by a Peltier cooling unit (12) to liquefy the gas for collection in the condensation catch container (14).
