Abstract:
1. The method of removal and isolation of impurities in a gas stream, comprising the steps of: a.) flowing said gas stream though a first stage scrubber having an operating pressure, such that said gas stream undergoes counter-current contact with sea water, sequestering a portion of said impurities and a portion of said gas stream in said sea water, so as to provide first stage sequestered sea water, and a purified gas stream; b.) flowing said first stage sequestered sea water through a second stage scrubber having a lesser operating pressure than said first stage scrubber, providing a second stage pressure differential; c.) utilizing said second stage pressure differential to flash impurities and gas sequestered from said first stage sequestered sea water, providing a second stage gas stream; d.) flowing said second stage gas stream though said second stage scrubber, such that said second stage gas stream undergoes counter-current contact with sea water, sequestering a portion of said impurities and a portion of said gas stream in said sea water, so as to provide second stage sequestered sea water, and a second stage purified gas stream.
