Petroleum refining units According to ExxonMobil's filings with the US DOE's
Energy Information Agency, the unit capacities for the Beaumont Refinery are presented below: The refinery has a
Nelson complexity index of 9.0, making it moderately complex. The refinery has three crude trains. The smallest is CDU A110,000 bpd. The second crude unit is CDU B 274,000 bpd. The newest CDU C was designed for lighter crude oils produced by shale crudes and light tight oils and is of 250,000 bpd of capacity. Starting in 2019, the refinery underwent a major expansion with a 65% increase in its nameplate capacity as part of a $2 billion program.
KBR was contracted to lead the work with a scope that covered offsite facilities and interconnecting units within the expansion This followed ExxonMobil's earlier contract with
TechnipFMC PLC for EPC services on four new units, including an atmospheric pipe still, hydrotreater units, and a benzene recovery system. The refinery has a large lubricants plant located on 27 acres within the refinery. The lubes plant produces 160 million gallons of

Electricity generation The refinery has three power plants that are integrated to provide steam and thermal heating to the refinery, in addition to selling electricity to the grid. These are:
Petrochemical units The refinery is also integrated with a large ExxonMobil petrochemical facility that is collocated on the same plot. Total ethylene cracking capacity for the site is currently 816,000 tons per year according to the
