摘要: A process for the recovery of halogenated hydrocarbons from a gas stream comprises passing the gas stream through a bed of hydrophobic molecular sieve adsorbent, preferably of the high silica zeolite type. Such adsorbent has pore diameters large enough to permit molecules of the halogenated hydrocarbons to pass therethrough and be selectively adsorbed in the large internal cavities of the crystal framework, whereby the halogenated hydrocarbons are removed. The gas is continued to be passed through the bed of adsorbent material until the material is saturated to the extent that breakthrough of the hydrocarbons is determined. The adsorbent material with adsorb phase of halogenated hydrocarbons is removed from the machine and regenerated by exposing the saturated material to an inert purging gas stream under conditions which desorb the halogenated hydrocarbons from the adsorbent material into the purging gas stream. The halogenated hydrocarbons are then removed from the purging gas stream and purified to a purity for reuse of the recovered halogenated hydrocarbons.

摘要: A system and process for the recovery of at least one halogenated hydrocarbon from a gas stream. The recovery includes adsorption by exposing the gas stream to an adsorbent with a lattice structure having pore diameters with an average pore opening of between about 5 and about 50 angstroms. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least one adsorbed halogenated hydrocarbon from the adsorbent. The at least one halogenated hydrocarbon (and impurities or reaction products) can be condensed from the purge gas and subjected to fractional distillation to provide a recovered halogenated hydrocarbon.
