In compliance with Environmental Protection Agency (EPA) standards, the unit is equipped with the latest technology designed to reduce by 98%, the sulfur content of diesel transportation fuel produced at the refinery.

The new unit has a production capacity of 42,500 barrels per day (bpd) of ULSD, which constitutes the majority of Lemont’s overall distillate production of 55,000bpd refined from heavy crude.

The CITGO Lemont Refinery will now be able to produce 100% ULSD, in addition to other high-quality refinery products such as gasoline, jet fuel and other specialty middle distillate products.

In addition to Lemont, the CITGO Corpus Christi, Texas refinery will soon introduce their own upgraded ULSD facility that will be able to produce 100% ULSD.

The CITGO Lake Charles Manufacturing Complex in Louisiana has been producing ULSD since 2006.
