Abstract
Official abstract text for this publication.
Disclosed herein is a system comprising an evaporation unit comprising a first heat exchanger in fluid communication with a second heat exchanger; where the first heat exchanger is operative to heat an effluent stream comprising an amine solvent and/or amine byproducts and water and to discharge the effluent stream to the second heat exchanger; where the second heat exchanger is operative to convert the effluent stream into a distillate stream and a concentrate stream; and a reverse osmosis unit in fluid communication with the evaporation unit; where the reverse osmosis unit comprises a first reverse osmosis unit that is operative to receive the distillate stream and to separate water from byproducts of the amine solvent such that the water has a purity of greater than 95%, based on the weight of the distillate stream.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: discharging an effluent stream comprising an amine solvent or byproducts of the amine solvent and water to a first heat exchanger; heating the effluent stream in a first heat exchanger; discharging the effluent stream from the first heat exchanger to a second heat exchanger; producing a wet steam stream in the second heat exchanger; separating the wet steam stream into a vapor and a liquid and returning the liquid to the second h…
