At the end of 2023, forty Grasys-made membranes for the Membrane Helium Concentrate Recovery Unit (MHCRU) were delivered to the Chayanda field of Gazprom Dobycha Noyabrsk LLC. All membrane elements have passed the incoming inspection. Each element has been subjected to individual testing on the test bench. The principle purpose is to check the membrane gas separation properties before starting operation.
The membrane technology for helium concentrate recovery makes it possible to recover helium from the extracted crude hydrocarbons. The process of helium recovery from natural gas using a two-stage membrane unit has never previously been used in the world on the implementable scale, which makes it a breakthrough. Currently production infrastructure of the field includes six process trains of the MHCRU membrane separation skid. They ensure fulfillment of contractual obligations in terms of gas composition.
The elements supply has been provided by JSC Grasys. It is the company that was the first in Russia to start the production of hollow fiber gas separation membrane elements for helium concentrate recovery. In line with the import substitution policy, Gazprom Dobycha Noyabrsk LLC makes a choice of the best process engineering solutions among Russian manufacturers. Ground-breaking home equipment ensures the reliability of all production processes without any supply risk.
Background information
The Chayanda oil and gas condensate field is one of the largest in Eastern Russia. It is home for formation of the Yakut gas production center and the resource base for the Power of Siberia gas pipeline (together with the Kovykta field in the Irkutsk region).
The Chayanda field was discovered in 1983 (Gazprom received a development license in 2008). Gazprom Dobycha Noyabrsk LLC took on the role of the job requester, and is the operating company now.
The field is located in the Lensky district of the Republic of Sakha (Yakutia). In terms of supply level (B1+B2) it belongs to the one-of-a-kind category - 1.2 trillion cubic meters of gas. Design annual capacity is 25 billion cubic meters of gas. The gas features a complex blend composition, including vast amounts of helium.
The Chayanda oil and gas condensate field has a complex geological structure and special thermobaric formation conditions (pressure and temperature). Accordingly, Gazprom puts in the practice cutting-edge engineering achievements for its development.
