  • System and method for treatment of water and disposal of contaminants produced by converting lighter hydrocarbons into heavier hydrocarbon
    Patent number: 6794417
    Abstract: A system and method are provided for treatment and disposal of water produced by converting a lighter hydrocarbon to a heavier hydrocarbon using a Fischer-Tropsch process. The system and method also provide for disposal of contaminants associated with the conversion process using a combustion chamber of at least one gas turbine. Water produced by the Fischer-Tropsch process may be used to wash or scrub synthesis gas in a synthesis gas water wash column prior to the synthesis gas entering a Fischer-Tropsch reactor. Contaminated water from the synthesis gas water wash column may be directed to a water stripping column which uses steam from the Fischer-Tropsch reactor to scrub or clean the contaminated water. A stream of contaminated steam and undesired contaminants preferably exits from the water stripping column and is directed to the combustion chamber of at least one gas turbine.
