PJSC Gazprom Neft has completed installation of the main section for its project to expand delayed coking capacity at its 430,000-b/d Omsk refinery in Western Siberia as part of the operator’s second phase of its ongoing modernization program to reduce environmental impacts and improve processing capacities, conversion rates, energy efficiency, and production qualities at the site (OGJ Online, Feb. 15, 2018).
A reinforced concrete frame construction standing more than 28 m high and supporting main equipment—including two coking ovens weighing 1,200 tonnes—for the future 40,000-b/d coking complex has now been installed, Gazprom Neft said.
The revamped coking complex, which will reduce environmental impacts and improve refining efficiency at the site, is scheduled to be commissioned in 2021.
Once in operation, the reconstructed delayed coking unit will enable full processing of heavy oil fractions to increase gasoline and diesel production at the refinery, as well as produce 38,700 tonnes/year of needle coke, the operator said.
Together with other projects forming the second phase of the Omsk refinery’s modernization project, the revamped coking complex will increase the site’s conversion rate to 97% and increase light-product yield to 80%, Gazprom Neft said.
Gazprom Neft—which confirmed it already has completed installation of three major coking ovens, each 28.5 m long and weighing 197 tonnes—said it also will replace process heaters and secondary refining columns, as well as add an additional tank farm and automated control system, as part of the coking reconstruction project.
The company said its current investment in the project stands at 5.2 billion rubles.
As part of its first and second-phase modernization works at the site that started in 2008, Gazprom Neft has, to date, invested a total of 300 billion rubles at the Omsk refinery (OGJ Online, July 26, 2017; July 12, 2017).
