Advanced controls pay out in 6 weeks at Texas refinery
- Marathon Oil Co., Texas City, TX (United States)
- Inferential Control Co., Broken Arrow, OK (United States)
Marathon Oil Co. installed advanced controls on two crude units and a fluid catalytic cracking unit main fractionator at its 70,000 b/d Texas City, Tex., refinery. The advanced controls were based on inferred properties supplied by an outside vendor, who also provided consulting and assistance during the implementation phases. (Inferred properties are on-line computations for estimating laboratory test properties, such as ASTM boiling point and flash point, that are used for product quality control.) The paper discusses inferred properties, bias updating, control strategies, control implementation, and post-project work, including fuzzy logic, the statistical quality control program, benefits, and availability.
