WebThe plant will be built at Yaraktinsky field, approximately 200 km north of the city of Ust-Kut, in Irkutsk Region, Russia. The plant is expected to be commissioned in the beginning of 2024. Prior, in 2024, Cryo Technologies prepared a FEED (Front-End Engineering and Design) Study report for the helium purification and liquefaction facilities ... WebCryogenic separation units compress the crude Helium, cooling the gases at subzero temperatures until they are liquified. Once liquified, the Nitrogen and methane gases are drained. After this cooling process, heat and Oxygen are added to remove any Hydrogen left over. When Hydrogen and Oxygen molecules meet, they create water.
WebHelium has a very low viscosity, a high diffusion coefficient, and the smallest atom of any element. These characteristics make helium very hard to contain. If a system has a leak, helium will escape. Helium gas is therefore used to test for leaks in high vacuum systems, fuel systems, and other containments.
