METHOD OF OIL COOLING IN OIL SYSTEM OF GAS TRANSFER SET AND GAS-OIL HEAT EXCHANGER FOR IMPLEMENTING THE METHOD Russian patent published in 2004 - IPC

FIELD: gas transfer systems. SUBSTANCE: method is designed for cooling oil in oil system of gas transfer set provided with gas-oil heat exchanger with possibility of using natural gas transferred along pipeline as cooling medium and using as intermediate heat carrier water solution of substance neutral to oil and gas featuring low freezing temperature, for instance, water solution of ethylene glycol. Gas-oil heat exchanger for cooling of liquid forming fire-and explosion-hazard mixture with gases, for instance, oils, has first circuit made in form of plate channels for cooled medium and second circuit in form of tubular channels for gas, interconnected by intermediate circuit for neutral heat carrier. EFFECT: provision of simple and reliable method of oil cooling. 3 cl, 1 dwg
