McDermott International Inc. said PJSC Lukoil subsidiary OOO LUKOIL-Nizhegorodnefteorgsintez granted it a significant contract for the engineering, procurement and construction of a delayed coker unit in Kstovo, Russia, according to an Oct. 16 release.

The delayed coking complex, which will have the capacity to process 2.1 million tons of refinery residues per year, will be built at the 17 million-ton-per-year Kstovo refinery in central Russia's Nizhny Novgorod region. The complex will also include a diesel hydrotreater, gas fractionation unit, sulfur and hydrogen production units along with associated systems.
