Patent ID: 8491712

Claim:
A dehydration system comprising: an absorber receiving an input stream of wet gas and an input stream of solvent, said absorber producing an overhead stream of carry-over solvent and dry gas and a stream of wet solvent; a knock-out drum receiving the stream of carry-over solvent and dry gas, said knock-out drum producing a dry gas stream and a carry-over solvent stream; a reflux coil receiving the stream of wet solvent and the carry-over solvent stream, the stream of wet solvent and the carry-over solvent stream forming a rich solvent stream; a flash drum fluidly coupled to said reflux coil to receive the rich solvent stream, said flash drum producing a flash gas stream and a flashed rich solvent stream; a column receiving the flash gas stream and an input stream of inert gas, said column producing a first overhead stream and a pure-solvent stream; a stripper receiving the flashed rich solvent stream and the first overhead stream, said stripper producing a second overhead stream and a stream of stripped solvent; and a reboiler receiving the stream of stripped solvent, said reboiler producing a vapor-liquid stream in flow communication with said stripper and a semi-lean solvent stream in flow communication with said column, wherein said stripper and said column are configured to strip the flashed rich solvent stream with the flash gas stream and the input stream of inert gas to produce the pure solvent stream.
