摘要
A method for circuit-parametric analysis of the efficiency of the heat-and-power system of the energy complexes at gas and natural-gas condensate processing plants is proposed. An energy complex of an alternative structure with an independent source of thermal and electric energy integrated into the production line has been developed. The energy carriers are produced accompanied by recovery of the secondary energy resources, waste, and effluents. Using the developed information-analytical software, multicriterion assessment of the efficiency of the alternative energy complexes and its systems based on independent energy sources of the combined-cycle cogeneration plant type has been performed for the gas processing plant in Astrakhan and the most effective equipment composition variant has been determined. The effect of the basic technical and economic factors on the economic efficiency has been established. The investments in construction of the power- and water-supply system within the plant’s energy complex pay off in 8- years.
