At the moment, dozens of specialists from the customer of the Gazprom Pererabotka Blagoveshchensk project, NIPIGAZ, the supplier of Linde equipment, are involved in commissioning tests.
в Ђ ) are the longest and take about 30 days.

The height of the methane recovery column вЂ“ 88 meters, almost a thirty-story building. Its maximum diameter is 6 meters, weight вЂ“ over a thousand tons. The demethanizer operates at a pressure of 30 atmospheres, and the temperature in the process of cooling down the gas drops to minus 110 degrees Celsius.
в Ђ
The processes of separation of dried natural gas in the demethanizer are provided by the interconnected operation of multi-flow cold block heat exchangers and feed gas expanders. A mixture of liquid hydrocarbons (C2+ fraction) from the bottom of the demethanizer column is sent to the deethanizer, where it is separated into ethane, which will be supplied to the Amur GCC, and a wide fraction of light hydrocarbons for further processing.
в Ђ
The mixture of methane, nitrogen and helium from the top of the demethanizer column is sent to the denitrogenation section to recover the nitrogen-helium mixture in the nitrogen removal columns. Further, the purified methane fraction as a commercial gas is supplied to the Ladoga gas compressor units. for transportation along the Eastern route.
в Ђ
In turn, the nitrogen-helium mixture will go to the helium purification, liquefaction and packaging unit, where nitrogen and other impurities will be removed, and ultrapure helium (99, 95%) will be shipped in ISO containers for shipment by road to the helium hub in Vladivostok.
в Ђ
In 2021, the first and second feed gas processing lines will be put into operation at the Amur GPP ( each with a capacity of 7 billion cubic meters of gas per year) and one helium purification and liquefaction unit with a capacity of 20 million cubic meters. m of gas per year.
