METHOD OF REMOVING AND RECOVERING AROMATIC HYDROCARBONS AND WATER FROM A GAS STREAM

摘要

The present invention relates to a method of simultaneously removing and recovering aromatic hydrocarbons and water from a gas stream wherein the gas stream is intimately contacted with a stream of liquid absorbent so that the aromatic hydrocarbons and water contained therein are selectively absorbed and removed thereform. The resultant stream of water and aromatic hydrocarbon rich liquid absorbent is heated in a reboiler so that the absorbed components are vaporized and separated therefrom and the stream of liquid absorbent is reconcentrated. The separated aromatic hydrocarbon and water vapors are withdrawn and recovered and the reconcentrated liquid absorbent is recycled into intimate contact with the gas stream.
