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.

This article presents the results of testing a horizontal tubular reactor for pyro-gasification of pulverized oil shales to obtain shale gas. The parameters characterizing the thermokinetics of pyro-gasification and heat exchange between the chemically reacting flow of shale gas suspension and the wall of the reactor have been obtained. The algorithm for the reactor design, and the inherent calculation data are provided: residence time for particles in the reactor 0.3-0.4 s and thermal stress volume of reaction 18-27.2 GJ/(m 3 •h). It is shown that a unit having a tubular reactor exhibits higher performance characteristics compared to existing systems for thermal processing of solid fuels.
