HOUSTON, May 28 -- ConocoPhillips let contract to Mustang for modernization of a distributed control system in the Rodeo segment of its 120,000-b/d San Francisco refining complex.
The project covers reinstrumentation and upgrade of control systems for crude and coker units and supply of a coke-drum interlock system.
Mustang also will handle integration and fabrication of two remote instrument enclosures to house the control system equipment.
A Mustang unit received another contract from D-Cok, Houston, for front-end loading engineering to study the addition of coke drum bottom unheading devices at the refinery.
D-Cok is providing project management services to develop a scope and cost estimate for the delayed-coker project.
The proposed upgrade includes automating the coke drum unheading process, which involves opening the coke drum to remove accumulated coke.
The San Francisco refinery, which handles mostly heavy, high-sulfur crude, includes the Rodeo facility in the San Francisco Bay area and the Santa Maria facility in Arroyo Grande, Calif., 200 miles away.
The Rodeo plant receives intermediate products for upgrading by pipeline from the Santa Maria segment.
