Lukoil commissions Kstovo refinery’s deep-processing complex

PJSC Lukoil subsidiary LLC Lukoil Nizhegorodnefteorgsintez (NNOS) has completed construction and initiated startup of the operator’s long-planned deep conversion, delayed coking complex at its 17-million tonne/year (tpy) Kstovo refinery in central Russia’s Nizhny Novgorod region (OGJ Online, Mar. 24, 2021).

Once fully operable, the new 2.11-million tpy delayed coking plant will increase the refinery’s production of Euro 5-quality diesel production by 1.1 million tpy, as well as slash its production of fuel oil by 2.6 million tpy, Lukoil said.

Previously scheduled for startup in fourth-quarter 2021, Nizhny Novgorod’s new deep conversion, delayed coking complex also includes a:

• 2.11-million tpy delayed coker.
• 1.5-million tpy combined diesel fuel and gasoline hydrotreater.
• 50,000-cu m/hr hydrogen production unit.
• 425,000-tpy gas fractionator.
• 81,000-tpy combined elemental sulfur-sulfuric acid production unit (OGJ Online, Apr. 6, 2022).
