Marathon Petroleum restarts fuel units at Texas refinery sources say

Marathon Petroleum will restart the fluidic catalytic unit that produces gasoline and the Ultracracker hydrocracking units (HCUs) that produce diesel at its 631,000 barrels per day (bpd), Galveston Bay refinery in Texas City. This is according to people familiar with plant operations.

The sources say that Marathon will complete the repairs of the 64,000 bpd residual Hydrotreater at the Galveston Bay Refinery, which was damaged by fire, in mid-November. This is a month after the original plan.

Marathon spokesperson Jamal Kheiry refused to discuss the operations of the Galveston Refinery which is the second-largest refinery in the United States.

Sources said that the 140,000 bpd FCCU, and the 60,000 bpd Ultracracker had been shut down due to a malfunction. This occurred on 16 October.

Sources said that Marathon plans to restart both units by the weekend.

A fire that occurred on June 14 caused severe damage to the RHU. Sources said that although most sections of the RHU have resumed production the 400-production section – where the fire took place – is still being rebuilt.

FCCs convert gas oil into unfinished fuel under high pressure and heat using a fine silica powder catalyst.

Hydrogen and high pressure are used in conjunction with heat and pressure to convert gasoline into diesel or other motor fuels.

Hydrotreaters remove sulfur from motor oil and feedstocks using hydrogen in accordance with U.S. Environmental Rules. Reporting by Erwin Seba, Editing by Muralikumar Aantharaman and Sherry J. Phillips
