  • Patent number: 6881389
    Abstract: A system for removal of Hydrogen Sulfide (H2S) and/or Carbon Dioxide (CO2) from natural gas via absorption and disassociation utilizing a sea water contact system. In the preferred embodiment of the present invention, a series of counter current scrubber stages is provided, each configured to remove via absorption/disassociation a portion of the impurities, each stage having less pressure than the predecessor, each stage redirecting the purified gas to the preceding stage, until the contaminant level in the hydrocarbon gas stream has been reduced to an acceptable level. The hydrogen sulfide/carbon dioxide contaminants are thereby sequestered in the sea water utilized in the scrubber, which sea water may be further processed and/or re-introduced into the deep of a body of water, where the contaminants will remain isolated for hundreds of years. The present invention further contemplates and energy recovery system for greatly enhancing the efficiency of the system.

A pulley may be provided on the caisson above the water line, in the vicinity of where the doubler plate is to be mounted on the caisson. A cable having first and second ends is provided, the first end affixed to the bracing member in the vicinity of the doubler plate, the second end engaging the tugger or winch. In use, the tugger draws the cable so as to urge the doubler plate to the caisson above the water line in the vicinity of the installation area.
