METHOD FOR PREPARING NATURAL GAS FOR TRANSPORTATION Russian patent published in 2023 - IPC E21B43/34 

FIELD: gas industry.

SUBSTANCE: invention can be used in field preparation of gas condensate deposits. In one of the options, a method for preparing natural gas is claimed, including transportation of the produced fluid along pipelines from gas well clusters to complex gas treatment plants (CGTP), gas separation in inlet separators and plug traps, compression at a booster compressor station (BCS) in several stages and cooling at gas cooling plants after each compression stage. At the same time, in the section between the pipeline leading from the gas cluster pipelines and the entrance to the first separation stage of the CGTP, a trestle gas collection ring is installed, which is a closed pipeline circuit, located so that one section of the trestle gas collection ring is located above the other. Moreover, the separator inlet is connected to the upper section of the trestle gas collection ring, and the cork trap inlet is connected to the lower section of the trestle gas collection ring. In this case, the cork trap and the separator are connected in parallel to each other. According to the second variant of the method, the upper section of the trestle gas collection ring is connected to the separator inlet, and its lower section is connected to a pipeline to direct the liquid separated in the separator for further separation or disposal.

EFFECT: independence of the operation of the CGTP production line from the volumes of accumulated condensate in the pipelines and from changing the operating modes of the gas well pipelines, as well as to significantly simplify the method for removing gas-liquid plugs.
