The new unit at the Corpus Christi refinery is reducing the sulfur content of the diesel transportation fuel produced at the facility by 99.7%.
The steps involved in producing ULSD include adding hydrogen to remove the sulfur from the diesel and then recovering and converting those sulfur compounds into elemental sulfur, which is then sold into the fertilizer market.
Houston-based Citgo is a refiner, transporter and marketer of transportation fuels, lubricants, petrochemicals and other industrial products.
The company is owned by PDV America, subsidiary of Petroleos de Venezuela, the national oil company of the Bolivarian Republic of Venezuela.
