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.

The project aims to replace the temporary Let Down Station, installed in 2015, with permanent pressure reduction facilities at the expansion area of GS. This upgrade is intended to transport gas to the local market and supply the existing Sirte Oil Company (SOC) coastal gas pipeline with an increased capacity of 19.5 MSm3/d of sales gas at a higher pressure of 51 Bar.
