HOUSTON (Reuters) - Phillips 66 is repairing the main gasoline-producing unit of its 253,600 barrel per day (bpd) Alliance, Louisiana, refinery before finishing the restart, Gulf Coast market sources said on Friday.
During a restart attempt following the refinery’s shutdown due to Tropical Storm Barry, portions of the 120,000 bpd gasoline-producing fluidic catalytic cracking unit (FCCU) were found to be plugged, the sources said.
A Phillips 66 representative was not immediately available to discuss operations at the Alliance refinery.
In addition to the FCCU, the 35,000 bpd alkylation unit remains shut at the refinery.
The FCCU uses catalyst under high heat and pressure to convert gas oil into unfinished gasoline.
The fine powder catalyst can become plugged as it circulates through the unit from the reactor, where it mixes with gas oil, to the regenerator, where excess carbon is removed so it can be used again in the reactor.
Alkylation units convert low-octane refining byproducts into octane-boosting components that are blended into gasoline. Alkylation units are often shut when FCCUs are out of production.
