Abstract
A method and apparatus for recovering water and light aromatic hydrocarbons from a wet gas stream, by contacting the wet gas stream with an absorbent for the water and light aromatic hydrocarbons in a contactor to absorb the water and light aromatic hydrocarbons and produce a water and light hydrocarbon laden absorbent stream and a dried gas stream. The water and light aromatic hydrocarbon laden absorbent stream is heated in a regenerator to produce a vaporous water and light aromatic hydrocarbon stream and a lean absorbent for recycle to the contactor. The vaporous water and light aromatic hydrocarbon stream is passed to a condenser where liquid water and liquid light aromatic hydrocarbons are recovered and where a light gas stream is recovered for use as a fuel gas for the regenerator.
