[Nigeria] Dangote Refinery Contracts DuPont Technology for Clean Emission

DuPont Clean Technologies announced that Dangote Oil Refinery Company Limited has commissioned a range of advanced proprietary equipment from DuPont for the construction of a new refinery in Lekki, an emerging seaport and manufacturing hub, located in the east of Lagos, Nigeria’s top commercial city.

Construction of the new refinery is part of a strategy to boost the country’s refining capacity. Dangote plans to turn 650,000Barrels of crude oil per day into 59 Million litres of gasoline; 20Million litres of Kerosine and 29Million litres of diesel per day, at peak performance.

“The innovative DuPont technology will allow Dangote to maximize quality and profitability while minimizing its environmental impact”, DuPont Clean Technologies says in a statement. “DuPont will be supplying Dangote with proprietary equipment for STRATCO® alkylation unit, MECS® sulfuric acid regeneration (SAR) unit, MECS® DynaWave® sulfur recovery unit (SRU) tail gas scrubbing, and BELCO® EDV® fluid catalytic cracking unit (FCCU) stack scrubbing that will help Dangote meet gasoline pool octane and emissions requirements”. The MECS® DynaWave® and BELCO® EDV® scrubbing technologies are leading refinery scrubbing technologies, also licensed and designed by DuPont. They offer ultimate emission control reliability and continuous operation.

At 650,000BOPD input, the Dangote refinery, on course for commissioning in 2020, is set to become the largest single-train refinery in the world. Within the same complex in Lekki, a petrochemical plant delivering 1Million Tonnes of polypropylene, a fertiliser plant with capacity for 3Million Tonnes of Urea Per Annum and a 3Billion cubic feet per day gas project pumped through 1,100km of subsea pipelines from the country’s south east to Lagos, are collocated.

“We are delighted to be supporting Dangote on a project that is of such critical importance to creating economic growth and opportunity in Nigeria,” said Eli Ben-Shoshan, global business leader, DuPont Clean Technologies. “Our aim is always to enable our customers to meet their emissions targets easily and efficiently with the help of cost-effective technologies and services that offer them value and flexibility while minimizing the impact on the environment.”

The new 27,000 Barrels Per Stream Day (BPSD or1,060 KMTA) alkylation unit and the 260 Metric Tonnes Per Day (MTPD) SAR unit will allow the facility to produce high octane, low sulfur, low RVP alkylate with zero olefins. Designed to meet world standards for particulate matter and SOx emissions, the DynaWave® wet gas scrubber will ensure full-time compliance with emissions regulations on both 115 ton per day SRUs, and the BELCO® EDV® wet gas scrubber will reduce the stack emissions from the FCCU as well as provide a purge treatment to condition the scrubber effluent. Both of the SRUs and the FCCU are supplied by other licensors.

Despite producing 2.12MM BOPD crude oil in 2015, Nigeria traditionally imports 80% of domestically consumed refined product, as national refining capacity is low, at 0.002BPD per capita.

“Licensed and designed by DuPont, the STRATCO alkylation technology is the established global leader in the industry with over 90 units licensed worldwide and more than 850,000 BPSD (33,300 KMTA) of installed capacity. For over 80 years, the STRATCO technology has helped refineries safely to produce cleaner-burning fuel with high octane, low RVP, low sulfur and zero olefins”, DuPont explains in its statement.
