340,000bpd Dos Bocas Refinery, the Biggest Refinery Project in Mexico

The Dos Bocas refinery is a 340,000 barrels per day (BPD) oil refinery, the biggest of its kind in Mexico, under construction on a 566ha piece of land near Dos Bocas maritime terminal, in the Paraíso municipality of Tabasco, the southeast region of the North American country.

The engineering and construction work for the refinery is divided into six packages the first of which at estimated to cost US$ 1.7bn involves the construction of distillation and coking plant facilities, while the second package whose cost is US$ 1.79bn includes the construction of a diesel hydro desulphurization (DHDT) unit, a Gasoil hydro desulphurization (HDS) unit, a naphtha hydro-treating (NHT) unit and a naphtha reformer.

The third involves the construction of fluid catalytic cracking (FCC) unit at an estimated cost of US$ 1.41bn while the fourth package involves the sulphur recovery plant, the gas recovery and treatment plant, and the hydrogen-producing plant for US$ 351.4M. The fifth and sixth packages involve respectively the construction of storage facilities and refinery integration services.

In total, the Dos Bocas Refinery will have 17 processing units including a combined distillation plant, a delayed coking unit, a fluid catalytic cracker unit, a naphtha hydro-treating unit, a naphtha reforming unit, a sulphur recovery plant, a gas recovery, and treatment facility, as well as a hydrogen-producing plant.

The delayed coking unit will convert the residue from the combined distillation plant into higher-value products, while the fluid catalytic cracker unit will use catalysts to break large distillation fractions into lighter products.

The hydro-treating unit will remove sulphur, nitrogen, and some aromatic compounds from the distillation fractions.

Mexicana de Recipientes a Presión is working with KBR and Constructora Hostotipaquillo, on package-6 of the Dos Bocas refinery project.

Van Oord in consortium with Grupo Huerta Madre received a contract for land reclamation works for the Dos Bocas refinery, the scope of which included the creation of 600ha of new land, 400ha of dynamic compaction, and 6 million m3 of dry earth movement.

China’s state-owned Bank of China and the Industrial and Commercial Bank of China (ICBC) are partly financing the construction of the Dos Bocas refinery whose cost is approximately US$ 8bn.

Project timeline

2019

In June the site preparation work for the refinery project began.

In July the contracts for five work packages including packages 1-4 and package-8 were rewarded and the following month i.e., August 2019, Mexico’s environmental regulator ASEA granted a construction permit for the project.

2020

By the end of 2020, the project was reportedly between 20 and 25% complete, with a 2022 start date.

In the same year, it was announced that the Dos Bocas refinery project could cost up to US$ 12.4bn, up from the latest US$ 8.9bn budget, which was already adjusted from the original US$ 8bn cost.
