Keywords: Urengoy oil and gas condensate field, integrated gas treatment units, ethane-containing gas, formation fluid preparation of Achimov deposits, low-temperature separation of gas, hydrate formation inhibitor, reduction of dropping liquid carryover at natural gas treatment units, measurement devices for measuring dropping liquid carryover, determination of dropping liquid carryover from separators, measurement of dropping liquid carryover from low-temperature separators, cyclone – a dropping liquid carryover meter, indirect methods for determining dropping liquid carryover, chromatographic method for determining dropping liquid carryover

Annotation:

The quality of field-treated gas largely depends on the efficiency of liquid separation in gas separators of complex gas treatment plants. Imperfect design of drying units leads to the carryover of dropping liquid, deterioration of commercial gas quality and irreversible losses of valuable hydrocarbon components C3+. In this regard, an urgent task is to monitor the operation and evaluate the efficiency of technological equipment. The article discusses the problem of the accuracy of measuring the droplet liquid carryover when using the equipment of complex gas treatment plants. Information is presented on some methods that are applied for determining droplet carryover, both direct and indirect, schematic images of the structural elements of dropping liquid carryover meters are given, and the optimized design of a device for measuring dropping liquid carryover, developed by specialists of Gazprom dobycha Urengoy LLC, is described.
