    摘要： The proposed method and the installation are intended for application in systems of reduction of natural gas from high—e.g. in a borehole or in a main pipeline down to the pressure value required for the consumer.The essence of the proposed method is that in the known method of utilization of natural gas energy in the process of gas pressure drop from increased, e.g. in a gas main pipeline down to the required value by conversion of natural gas expansion energy to mechanical energy with the aid of the gas cooled down in the process of pressure drop as a cooling agent, the innovation is multi-stage gas pressure drop and multi-stage take-off of generated cold.The essence of the proposed method is that a utilization power installation the inlet of which is connected to high pressure gas borehole or main pipeline (3) and the outlet—to low pressure natural gas pipeline or to low pressure natural gas consumer (7, 9), comprises a gas expansion machine (e.g. expansion gas turbine) consisting of two or more components (1, 2), arranged in the direction of pressure drop, converter (4) of mechanical energy, e.g. an with the gas expansion machineOM, and two or more heat exchangers (6, 8).
