In order to reduce the gas pressure level of the main gas pipeline to a safe level, it is customary to use a gas distribution station. GDS differ in performance, purpose, and gas consumption.

The supply of gas to enterprises and populated areas is ensured through the following operations:

gas purification from impurities;

decrease in blood pressure;

odorization;

Maintaining gas reporting before its supply.

All stages of gas processing must be monitored by a specially trained person - a gas distribution station operator.
