METHOD OF MAINTAINING QUALITY OF GAS DEW POINT TEMPERATURE IN PROCESS PIPELINES OF COMPRESSOR SHOP WHICH IS IN RESERVE FOR LONG TIME Russian patent published in 2025 - IPC F17D1/02 F17D3/14 

FIELD: transportation.

SUBSTANCE: invention relates to pipeline transport and can be used in operation of compressor stations with a scheme of parallel piping of a group of gas compressor units (GCU) with individual gas air coolers. Objective of the invention is to maintain the quality of water dew point temperature (WDPT) of natural gas in accordance with the requirements of regulatory documents without launching a group of gas compressor units on the shop "ring" and removing moisture from the gas by blowing dust traps (DT) of the shop gas cleaning unit through plugs. Technical result is achieved by changing the existing flow pattern of natural gas from the connection unit (CU) through the input loop to the DT and then to the fuel and pulse gas preparation unit (FPGPU). According to the new scheme, gas passes from the CU through all process gas pipelines, including the inlet manifold, the outlet manifold, the outlet manifold of the DT, gas passes to FPGPU for use in own process needs. This ensures constant replacement of gas in process pipelines of the compressor shop with “fresh” gas from the linear part of the main gas pipeline.

EFFECT: thus, constant temperature is maintained and formation of moisture in internal cavities is prevented, which allows not to start GCU on shop "ring" with subsequent blowing of DT for moisture removal from process gas.
