Mexican state oil company Pemex's refining subsidiary Pemex Refinación this month will launch the engineering and construction tender for gasoline desulfurization plants at its Cadereyta refinery in Nuevo León state and Madero refinery in Tamaulipas state.
The plants aim to reduce the sulfur content of gasoline in order to lower emissions, Pemex CEO Jesús Reyes Heroles told correspondents.
Following the tender, Pemex Refinación will tender low-sulfur gasoline plants at its Minatitlán and Salina Cruz refineries in Veracruz and Oaxaca states.
Pemex will launch the tenders between April and May, Reyes said, adding it will be the final package in the company's gasoline quality project.
The company has a tender out for desulfurization units at its Tula refinery in Hidalgo state and Salamanca refinery in Guanajuato state, with bids due on February 12.
Pemex Refinación will invest US$250mn in its gasoline quality project in 2009, and roughly US$1.98bn through 2012, Reyes Heroles said.
Meanwhile, the subsidiary will invest US$76mn in its project to improve diesel quality in 2009 and some US$2.60bn through 2012.
The project entails building five new desulfurization units and four storage tanks as well as modernizing 18 processing and 21 complementary plants.
