Petrobras Ltd planned to develop Rio de Janeiro Petrochemical Complex – COMPERJ Project in Itaborai, Rio de Janeiro, Brazil. Skanska Inc was the designer. WorleyParsons Ltd (FEED contract), Axens Ltd, ExxonMobil Chemical
Ltd, Uhde Ltd, Shaw Energy and Chemicals
Inc, Emerson Process Management Regulator Technologies Inc were the technical consultants. A consortium of Skanska Inc, Promon Ltd, and Engevix Ltd was the EPC contractor of the atmospheric vacuum distillation unit. Alusa Engenharia Ltd was the EPC contractor of the catalytic hydrocracking unit. A consortium of Techint Engenharia Ltd and Andrade Gutierrez Ltd was the construction contractor of a coking unit. Cadae Corp was the supplier of treated water to the refinery. China National Oil & Gas Exploration & Development Co Ltd
(CNODC) was the construction contractor. The project covered the construction of a land area of 45 sq. km with a refinery facility that could process 150000 bbls/day of domestic heavy crude, which would form the basis of the feedstock for 1300000 t/y ethene, 880000t/y propane, 600000t/y benzene, 700000t/y paraxylene (PX), and 157,000t/y butadiene. In addition, the facility would to produce 50000t/y styrene, 600000t/y ethylene glycol (EG), 80000t/y polyethylene (PE), 850000t/y polypropylene (PP), 500000t/y purified terephthalic acid, and 600000t/y polyethylene terephthalate (PET). The project also included the construction of an integration center and a liquid distribution center. The project was one of the largest industrial/petrochemical projects in the world in terms of the cost. It aimed at increasing the production of basic petrochemical feedstock and operating in petrochemicals on an integrated basis with the Petrobras Group’s other businesses. It promoted the Belt and Road Initiative cooperation between Brazil and China. The project was first initiated in 2004. It got resumed at the end of 2014 and again in April 2015 because of Petrobras Ltd.’s financial troubles, company corruption, and associated government investigations. At the end of 2019, it was found not economically feasible to complete by China National Oil and Gas Exploration and Development Co. After the cancellation of the project, Petrobras Ltd requested a survey of alternatives for the Comperj area and studied the integration of its 232,000-b/d Duque de Caxias (Reduc) refinery in Rio de Janeiro state with some mothballed Comperj units for production of high-quality basic lubricants and fuels from Reduc intermediate products sent for processing at Comperj via pipelines. The study also included the possibility of building a thermoelectric plant using natural gas from Brazil’s pre-salt with other investors.
