Mexico’s Petroleos Mexicanos (Pemex), through a contractor, has let a contract to a subsidiary of Yokogawa Electric Corp., Tokyo, for automation work at an ultralow-sulfur diesel (ULSD) fuel plant to be built at its 275,000-b/d Hector R. Lara Sosa refining complex in Cadereyta, Nueva Leon, in northeastern Mexico.
Yokogawa de Mexico SA will provide installation and engineering for an integrated monitoring and control system for the diesel plant’s hydrodesulfurization (HDS) and sulfur recovery units, the company said.
The company said it expects to complete installation of all systems and products for the project by first-half 2015.
The diesel plant, which will have the capacity to produce 35,000 b/d of ULSD from naphtha purified at the Cadereyta refinery, is slated to be commissioned during first-half 2017, Yokogawa said.
Pemex previously awarded a $390 million engineering, procurement, and construction contract for the Cadereyta ULSD plant to Cobra Instalaciones Mexico SA, a subsidiary of Spanish EPC-firm ACS Group, ACS said.
In addition to the HDS plant, Cobra will provide a 120,000-tonnes/day sulfur recovery unit as well as a 10,000-b/d wastewater treatment plant, ACS said.
Pemex also commissioned an ULS gasoline unit at the Cadereyta refinery in September 2013 as part of its company-wide Clean Fuels Project. The unit, which has a ULS gasoline nameplate production capacity 42,500 b/d, will be able to produce gasoline with a 30 ppm sulfur content, down from a previous 800 ppm, Pemex said in its 2013 annual report, which was released earlier this year.
