Field hydrocarbon gas treatment for transportation at regions of permafrost soils propagation

Authors: S.S. Ivanov, M.Yu. Tarasov, I.Z. Fakhretdinov (Giprotyumenneftegaz OAO, HMS Group, RF, Tyumen)

Key words: gas treatment, separation, gas complex treatment unit.

At designing systems of gas gathering, treatment and transportation in an oil-gas condensate fields in the conditions of permafrost soils propagation, it is necessary to provide for technological solutions, ensuring the integrity of soils in the frozen state. So, to avoid thawing of permafrost soils the temperature of transported hydrocarbon gas shall not exceed 2 °C, that causes cooling plant appearance in the structure of the gas treatment complex. The basic flow diagram of hydrocarbon gas treatment for transportation, allowing to apply compressing units of less power due to increase of efficiency of use of domestic energy resources of the gas treatment complex, is presented.
