Bechtel Acquires Chevron’s Waste Water Treatment Technology

Bechtel 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.

The WWT 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., a wholly owned subsidiary of Bechtel.
