Abstract

In gas condensate fields, low-temperature separation process is mainly used for primary processing of gas. Cooling of well products in gas preparation systems is achieved by throttling them. As the reservoir pressure decrease, the amount of energy obtained decreases. This worsens the conditions for the preparation of gases. Therefore, raises a need to use additional energy sources. Analysis of the operating modes of gas treatment plants has shown that the energy obtained during the expansion of gas can be used rationally. Calculations have shown that the gas temperature at the outlet of turbodetander units during adiabatic expansion provides the required dew point for water and hydrocarbons. Keywords: gas; condensate; turbodetander; gas expansion; polytrophic; adiabatic; cold productivity; dew point.
