Polygeneration plants in the energy complex of oil and gas enterprises: the concept of synthesis and a method for assessing efficiency

Abstract

Abstract The article proposes a concept for the synthesis of polygeneration plants as part of the energy complex of oil and gas enterprises, which expands the possibilities of inter-industrial integration of energy and technological systems in the direction of creating closed utilization cycles. An example of a complete set of equipment for an installation for the combined generation of energy resources, water and carbon black, utilization of wastewater and low-pressure hydrocarbon gases is given. A two-dimensional model of a multi-criteria efficiency index is proposed for the analysis of performance indicators and the efficiency of integration of polygeneration units with energy technology systems of oil and gas enterprises.
