HEAT EXCHANGER Russian patent published in 2012 - IPC B01D19/00 

FIELD: process engineering.

SUBSTANCE: invention relates to heat exchangers to be used in heat exchange in gas-fluid system in treatment of gas condensate and oil. Proposed heat exchanger comprises degassing tank and shell-and-tube neat exchanger arranged horizontally one above another and communicated via degassing tank vapor-fluid discharge branch pipe and heat exchanger overflow tube to make integral structure. Degassing tank is provided with U-like fluid tubular heater, overflow web, gas-fluid feed branch pipe and fluid discharge branch pipe. Said U-like fluid tubular heater is arranged under overflow web top edge. Said shell-and-tube neat exchanger is provided with coolant inlet and outlet branch pipes, and gas escape branch pipe. Heat-insulated overflow tube has its bottom end located below overflow web top edge.
