Grasys membrane plant to support petroleum gas conditioning for Rosneft

11 September 2013

As part of the Rosneft program for gas conditioning up to the pipeline parameters of the Gazprom unified gas transportation system, the membrane gas treatment plant of Grasys was selected for operation in the Krasnodar Territory, which is expected to come on stream in 2014.

The membrane plant is designed for production of dry stripped gas (DSG) ensuring compliance with the STO Gazprom 089–2010 requirements through preferential selection on the polymer membrane of the compressed gas mixture from the Smolenskaya and Klyuchevaya groups of the RN-Krasnodar fields.

The project specifics is associated with the conditions warranting significant changes in the gas flow. The Grasys plant is easily adaptable to gas flow variations within 30 to 100%. The specialists of the Grasys Engineering Center offered a high-tech solution allowing for complete disposal of gas treatment products.

Continuous control of the gas treatment quality at the Grasys equipment is carried out by the advanced dew point analyzer for water and hydrocarbons installed in the treated gas line at the plant output.

The plant combines the Grasys best experience in design, testing, invention and operation of various type membrane plants and stations dedicated for conditioning of natural and associated petroleum gases», underlined the Deputy Head of the Hydrocarbon Projects Department of Grasys Dmitry Solodov.
