Bechtel Acquires Chevron's Waste Water Treatment Technology
Purchase of WWT Expands Bechtel's Capabilities in Refining Industry
HOUSTON, Jan. 28, 2013
HOUSTON, Jan. 28, 2013 /PRNewswire/ --Bechtel announced today the company has
purchased Chevron's Waste Water Treatment (WWT) Process, a technology that
improves the efficiency of petroleum refineries. The WWT Process is a
proprietary, two-stage sour water stripping process that separates ammonia and
hydrogen sulfide streams from sour waters generated by a refinery's process
units. The technology also allows debottlenecking of sulfur plants and can
reduce the cost of new sulfur units, especially in refineries that process
high nitrogen crudes.
"This is a world-class technology that enhances our capability to deliver
customers high-quality, technologically superior water and sulfur processing
units more efficiently and cost effectively," said Scott Johnson, vice
president and general manager of Bechtel's Onshore Oil and Gas/Downstream
division. "This acquisition complements our current suite of refinery
technologies and continues our long-standing practice of making sure we have
the right resources to help our customers meet their needs."
The WWT Process was developed and improved by Chevron over the past 40 years.
The process achieves higher purity separation and recovery of ammonia from
sour water streams; reduces the size requirements of sulfur plants; and
removes operating problems associated with ammonia salts in sulfur units. The
stripped water is suitable for reuse or discharge through downstream treating
facilities. The high purity hydrogen sulfide is a premium feed to conventional
sulfur recovery units or sulfuric acid plants. And the ammonia may be
recovered for commercial sale, internal use, or separately incinerated.
The WWT Process technology is managed by Bechtel Hydrocarbon Technology
Solutions, Inc. (BHTS), a wholly owned subsidiary of Bechtel that provides
technology licensing and process consulting services to the oil and gas
industry. A leader in the refining, chemical, and industrial market, Bechtel
has built more than 375 refining and chemical projects around the world.
