ASSOCIATED PETROLEUM GAS TOPPING PLANT Russian patent published in 2019 - IPC F25J3/02 

FIELD: refrigerating equipment.

SUBSTANCE: invention relates to refrigeration engineering, and in particular to devices for separating gases using cold treatment, and can be used in oil fields to create mobile modular complexes for separating associated petroleum gas into gas condensate, which can be compounded with mineral oil, and into dry gas, which can be transported to the main gas pipeline, or can be used for personal needs or burned in a flare. Associated petroleum gas topping plant includes a refrigerating unit, a distillation column, a three-phase separator, a multi-flow heat exchanger, separator, a hydrate inhibitor injection system, or an adsorption drying system. Refrigerating unit operates in a single-stage cycle on a mixed refrigerant whose components are hydrocarbons.

EFFECT: improved weight and size characteristics, simplified design, reduced power consumption and increased thermodynamic efficiency.
