July 23, 2024--Written by Amir Richani for Industrial Info Resources (Sugar Land, Texas)--Petroleos Mexicanos SA de CV (Pemex) (Mexico City) has resumed its startup of the U-30000 delayed coker unit at its Dos Bocas Refinery, also called the Olmeca Refinery. The 105,000-barrel-per-day (BBL/d) unit started operations July 4, but it was halted due to a compressor section failure on July 6.

Pemex also is continuing with the commissioning, testing and pre-startup of several other units at its 340,000-BBL/d Dos Bocas Refinery. The refinery's cogen area recently experienced a string of failures, affecting turbines, generators, the heat recovery steam generator (HRSG) and the protection system, leading to reduced processing capacity.
