Sulfolane, also known as 2,3,4,5-tetrahydrothiophene-1,1-dioxide or tetramethylenesulfone, is an organicx000D
solvent, primarily used as an extraction solvent in the oil and gas processing industry. Sulfolane minimallyx000D
interacts with soil organics and is quite miscible and therefore highly mobile when released in ground waters.x000D
This leads to its significant offsite migration. There have been reports of sulfolane contamination in ground andx000D
surface waters around many gas processing sites.x000D
This project builds on our current research on degrading sulfolane using advanced oxidative as well asx000D
biological means. Our findings have indicated that sulfolane in water can be treated by various combinations ofx000D
advanced oxidative processes as well as by aerobic degradation. The proposal furthers the research andx000D
proposes to evaluate Delta Remediation Inc.'s Biologix® system to remediate sulfolane contaminated waters. Itx000D
will also investigate the application of nano photocatalysis for the treatment of sulfolane contaminated waters.x000D
It is expected that the two (Biologix® and nano photocatalysis) will lead to a cost effective technology to treatx000D
sulfolane contaminated waters.
