A technology concept has been developed that has significant potential as an economic means to clean up industrial waste-water streams, such as those from gas wells. The technology is based on formation of methane clathrate from a contaminated aqueous stream, by a newly discovered technique that greatly increases the rate of production of the clathrate. When clathrate solids are formed, the contaminants remain in the liquid phase, and the clathrate solids can then be decomposed to release pure water. In this study, MATRIC completed a preliminary techno-economic study of this novel concept and compared the findings with those for competing technologies for waste-water purification.
