The calculations of energy efficiency of the power capacity of the fuel gas using a two-line circuit expander-generator set (DGS) with parallel distribution of gas flow between the cylinders of the unit as part of the utilization expansion turbine installation (UTDU). It is shown that taking into account of the assumptions is provided as a capacity increase of DGS, and, accordingly, the development of their energy and a reduction in the unit cost of fuel.
the utilization turboexpander unit, the two-cylinders UTDU, the variable work mode, the energy efficiency, the fuel gas, the specific consumption of heat, the production of electricity.
