Reviewed are technologies and technical means, used in JSC "Tatneft" for treatment of petroleum gas, it is stated, that application of preliminary evacuation of gas from pipelines has enabled to sharply increase capacity and reduce material consumption of separators, and using of pipelines end parts design parameters as technological ones - not only to withdraw gas, but also to dispose of water, with simultaneous reduction of energy consumption for ballast pumping and decrease in the number of pipelines bursts. Given are studies results on petroleum gas utilization by using it as a fuel for power generation and by joint transportation together with oil through multiphase pumps.
