Abstract
An organic emissions elimination apparatus, and process for same, for substantially eliminating the emission of potentially harmful organic constituents, such as benzene, toluene and xylene ('BTX') into the ambient environment during dehydration of water bearing gas. The apparatus includes a first chamber which incorporates a membrane for use in association with a water absorbing material (such as triethylene glycol) which is operably displaceable and retained within the membrane fibers. Although the water vapors from the gas will permeate the membrane (and become absorbed by the triethylene glycol), the BTX will not be able to permeate the membrane. Accordingly, the BTX and the dehydrated gas will be discharged from the first chamber toward a point of use by conventional dehydrated gas using equipment. However, the glycol, and the water vapors absorbed therein, will be transmitted to a regenerator for separation therebetween--wherein the separated water vapors (without any BTX) will be discharged into the ambient environment, and the separated triethylene glycol will be reintroduced into the first chamber.
