FIELD: transportation. ^ SUBSTANCE: at compressor station for gas conditioning before its delivery to gas-main pipeline which station contains gas-compressor plants including centrifugal boosters driven by gas-turbine engines, heat exchangers for gas cooling, pipelines and locking elements, in each of gas-compressor plants on one shaft and in one housing with centrifugal booster driven by gas-turbine engine, gas turboexpander, at that, outlet of gas cooling heat exchanger which inlet is connected with booster output is connected with inlet of gas turboexpander outlet of which is connected by pipeline with gas-main pipeline, at that, gas-compressor plants with gas turboexpander are collected in pairs in block-containers with possibility for each of gas-compressor plants of one block-container to work in parallel or in series. ^ EFFECT: gas-main pipelines reliability enhancement by means of supplying to them compressed air of reduced temperature. ^ 3 dwg |
