PJSC Lukoil subsidiary LLC Lukoil Nizhegorodnefteorgsintez (NNOS) is nearing completion 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.

NNOS is currently finishing related construction works for the new 2.11-million tpy delayed coking plant, which once in operation, will increase he refinery’s overall product yield to 97%, with yield of light products reaching 74%, Lukoil said on Apr. 6.

Lukoil did not disclose a specific timeline for when it plans to officially commission the new plant, which previously was scheduled for startup in fourth-quarter 2021.

Separately, Lukoil also said NNOS is continuing to prepare design documentation for its earlier announced plan to add a new polypropylene complex at the Kstovo refinery. Upon formally breaking construction groundwork for the project last July, Lukoil said the planned polypropylene complex will process a feedstock of propylene supplied by the refinery’s two existing catalytic crackers to produce 500,000-tpy of product for other plastic manufacturers in the region.

Further details regarding the proposed petrochemical complex, however, have yet to be disclosed.

Deep conversion complex overview

Alongside its primary 2.11-million tpy delayed coker, Lukoil has said the new Nizhny Novgorod deep conversion complex also will include the following major units:

  • A 1.5-million tpy combined diesel fuel and gasoline hydrotreater.
  • A 50,000-cu m/hr hydrogen production unit.
  • A 425,000-tpy gas fractionator.
  • An 81,000-tpy combined elemental sulfur-sulfuric acid production unit.
