Currently, the share of produced together with oil in the fields gas usage does not reach the levels determined at the legislative level. According to official data, no more than 80% of the produced gas is used advantageously (the normative value is 95%). Combustion of associated petroleum gases is accompanied by the consumption of oxygen and the release of excess heat. This is detrimental to the ecology of the Earth, contributes to the greenhouse effect.

On the other hand, the combustion of gas produced with oil is irrational in the use of raw materials and creates lost commercial profit. The article considers the direction of utilization of associated gas as a raw material for obtaining high-quality motor fuel and other hydrocarbons, including synthetic oil. The process consists of autothermal reforming and the Fischer-Tropsch process.

A brief review of the experience of using such plants abroad is presented. The characteristics of plants for the production of ultra-clean diesel fuel with the use of APG gas caps for the fields of the Near Abroad of Russia are used as raw materials for APG.

The results of the analysis of the economic feasibility of the installation with a minimum consumption of associated gas of 50 million m³/year are shown. The main technical parameters of the plant are presented: productivity for the main product – diesel ultrapure fuel of the Arctic grade – and associated hydrocarbon products.

The dependence of the main performance indicators of the plant on its main product productivity is constructed. The range of productivity from 7000 tons/year to 141500 tons/year is considered. It is shown that with an increase in the capacity of the installation, the payback period, taking into account the discounting, is reduced, reaching 4 years at maximum power. At the same time, CAPEX costs about 180 million US dollars.
