Yokogawa to control new Pemex diesel plant

Yokogawa Electric has received an order from Spanish engineering and construction firm ACS to supply an integrated control and safety instrumented system solution for an ultra-low-sulfur diesel fuel plant that is being built for Pemex Refinacion.

To reduce air pollution caused by emissions of sulfur oxide, nitrogen oxide, and particulate matter, Pemex is promoting the use of low-sulfur diesel fuel and gasoline. 

This project involves the construction of an ultra-low-sulfur diesel fuel plant at the Pemex Cadereyta refinery complex, which is located in Nuevo Leon state in northeastern Mexico. The new plant will produce ultra-low-sulfur diesel fuel from naphtha purified at the Cadereyta refinery. 

This facility will have the capacity to produce 35,000 bpd of the desulfurized fuel, and is scheduled to come online in the first half of 2017.

For the monitoring and control of this plant's hydrodesulfurization unit and sulfur recovery unit, Yokogawa will deliver the CENTUM VP integrated production control system, the STARDOM network-based control system, the ProSafe-RS safety instrumented system for shutting down the plant under abnormal conditions, the Exaquantum plant information management system and other solution-based software packages, the GC8000 process gas chromatograph for analyzing gas composition, and a variety of field instruments for flow measurement.

Yokogawa de Mexico will be responsible for installation and engineering, and will also provide support with commissioning and the training of plant operators. 

Installation of these systems and products is scheduled to be completed by the first half of 2015.
