Cheyenne Refining LLC, a subsidiary of HollyFrontier Corp., Dallas, has let a contract to a division of Honeywell International Inc., Des Plaines, Ill., to provide technology for removing contaminants from industrial wastewater in order to meet stricter environmental discharge requirements at the 49,400-b/d (52,000-b/sd) Cheyenne, Wyo., refinery.
As part of the contract, Honeywell’s UOP LLC will supply its proprietary XCeed bioreactor technology to remove selenium from the refinery’s wastewater, the service provider said.
Scheduled to be implemented and commissioned on a turnkey basis sometime this year, the bioreactor will process about 1 million gpd of wastewater, Honeywell said.
HollyFrontier selected XCeed technology for Cheyenne specifically after demonstrations of its selenium-removal capabilities during field tests, as well as for its ability to help the company meet ongoing environmental commitments by further polishing the refinery’s treated effluent water, said Jim Stump, HollyFrontier senior vice-president, refining.
A value of the contract was not disclosed.
This latest contract follows a series of announced projects by HollyFrontier as part of its $325-million capital investment program during 2015-18 to expand, modernize, and enhance environmental mitigation efforts at its five US refining centers (OGJ Online, Jan. 5, 2016; Jan. 4, 2016; Sept. 8, 2015).
