EnSolve Biosystems awarded grant for SOx scrubber technology

Industry Database

EnSolve Biosystems has been awarded a grant to develop a prototype treatment device for the removal of hydrocarbons from sulfur oxide (SOx) scrubber treatment systems.

The $445,000 Phase II Small Business Innovation Research Grant comes from the National Science Foundation (NSF).

Current scrubber systems focus on the removal of SOx and nitrogen oxides (NOx) from ship engines, rather than hydrocarbons that typically end up in the scrubber effluent. Such effluent would likely violate International Maritime Organization (IMO) clean-water standards due to excess hydrocarbon levels. EnSolve’s technology (trade named EnScrub) addresses the hydrocarbon portion of this wastestream.

“The developed product will be an add-on device to SOx scrubber systems,” stated Jason Caplan, EnSolve’s CEO. “As such, EnScrub will complement, rather than compete with, scrubber companies. The Phase I work, completed in 2011, showed hydrocarbon reductions of greater than 99% from simulated scrubber effluent, so we are confident that we can scale the technology in a timely manner.”

The EnScrub technology uses a combination of physical and biological methods to treat hydrocarbons from scrubber effluent. The commercial-ready EnScrub product is anticipated to yield lower wastes and, consequently, lower operating costs than conventional technologies due to the “green” nature of the technology.
