Gazprom Neft’s Omsk Refinery has completed works on modernising the filtration system at its small cat-cracking facility, with the production complex now being equipped with a modern water treatment block. This new equipment, which guarantees zero atmospheric emissions, has made possible the dismantling of the flue fume stack. The project, involving total investment of RUB2.5 billion, is a key element in the second stage of the Omsk Refinery’s modernisation programme, being implemented by Gazprom Neft since 2008.
The main purification unit is a large-scale “scrubber” (a gas-purification or “wash” column), with a total height of 70 metres and weighing more than 200 tonnes, specially designed to remove production-related impurities from flue gases. The scrubber’s operation involves a modern steam “wet purification” system, with water subsequently undergoing filtration and being returned to the production cycle. The equipment emits no industrial effluents or wastes, all systems operate in “closed” mode, and there are no environmental emissions. The purification process is fully automated, with the filtration system being fully equipped with in-line control analysers, thanks to which data are transmitted for technological monitoring online.
Oleg Belyavsky, CEO of Gazprom Neft’s Omsk Refinery, commented: “Ecology is an absolute priority for the Omsk Refinery. Technologies to reduce environmental impacts are being systemically introduced at the plant. The Omsk Refinery was one of the first in Russia to use this cutting-edge gas-purification method in cat-cracking regeneration. This is an exclusively environment-focussed project, which supports our high standards in environmental safety.”Oleg Belyavsky CEO of Gazprom Neft’s Omsk Refinery
Gazprom Neft is continuing the full-scale modernisation programme at its Omsk and Moscow refineries, involving cumulative investment of more than RUB550 billion. The first stage of this modernisation has involved the construction and reconstruction of key technological facilities, allowing the complete transition to the production of Euro-5 fuels, significantly improving energy efficiency and environmental friendliness in production. The implementation of the second phase of the modernisation programme is ongoing, as a result of which conversion rate and the yield of light petroleum products will increase.
