Abstract

The article describe technological scheme of low-temperature separation of natural gas, intended for separation of low-boiling hydrocarbons fields with wells, having high and low reservoir pressure of natural gas. Proposed method of improvement of the technological scheme to increase the pressure of low-pressure gas wells in front of devices low-temperature separation through the use of the compressor, which is driven by the turboexpander. In the turboexpander gas due to the overpressure of the gas produced from high-pressure wells, extended to gas pressure, providing the temperature of the dew point in the low-temperature separation devices. The dependence of the gas pressure of low-pressure from high-pressure wells in three gas ration three gas ratios of costs to meet the low-temperature separation of natural gas. The proposed solution allows to produce gas from low-pressure wells without the use of a booster compressor station. Determined the gas temperature after mixing, high-pressure and low-pressure flows, which is lower than the temperature of the produced gas at the wellhead, which gives an additional positive effect in the process of low-temperature separation. Shows the dependence of the gas temperature after mixing, high-pressure and low-pressure flows from the pressure of low-pressure wells in three ratios of gas flow rate.
