PEMEX is investing in constructing two new coker plants at the Tula refinery and Salina Cruz refinery, scheduled to go online in 2024, to phase out fuel oil production. The Salina Cruz cracking refinery, located in Oaxaca, Mexico, is a non-integrated cracking facility owned by Petroleos Mexicanos. It commenced operations in 1979 and boasts a Nelson Complexity Index (NCI) of 8.1. Works on the Salina Cruz unit began in 2022. The plant is expected to contribute to the elimination of fuel oil and the increased production of ultra-low sulfur gasoline and diesel at the refinery.
