Abstract
The work is devoted to the urgent problem of using an alternative energy source of biomethane for gas supply to settlements. The effective use of biomethane in gas supply systems requires scientific substantiation, considering the entire range of technological parameters and operating conditions. The methods of graphs and parametric optimization are used to minimize the total reduced costs to the gas supply system to carry out the research. Based on the analysis of gas consumption by the municipal districts of the Belgorod region, a graphical dependence is built and an expression is obtained to determine the annual gas consumption by the population on the population size. The calculation of the mass of organic waste and the density of substrate formation is made, on the basis of which the potential for biomethane production in the municipal districts of the Belgorod region is determined. It has been established that the potential volume of biomethane in the Belgorod region is 633194 thousand m3 / year, or 11% of the total gas consumption. A diagram of the location of biomethane plants and gas pipelines for supplying biomethane to gas networks has been built. The optimal values of the technological parameters of the biomethane gas supply system have been established: the operating range of the biomethane plant depending on the substrate formation density, the length of the gas network for biomethane supply, depending on the gas consumption density.

Summary
Произведен расчет массы органических отходов и плотности субстратообразования, на основании которого определен потенциал производства биометана по муниципальным округам Белгородской области. Установлены оптимальные значения технологических параметров системы газоснабжения биометаном: производительность и радиус действия биометановой установки в зависимости от плотности субстратообразования, протяженность газовой сети для подачи биометана в зависимости от плотности газопотребления. Для оценки возможности получения и использования биометана в системах газоснабжения Белгородской области был произведен анализ потребления природного газа и расчет потенциала производства биометана на территории области. Для определения зависимости потребления газа от численности населения рассмотрим газопотребление муниципальными округами Белгородской области
