Problems solved by technology

[0004] When the oil and gas are condensed through the heat exchanger, the water vapor in the oil and gas will condense into frost, and the frost layer will gradually thicken with time, and the oil and gas channels of the heat exchanger will gradually be blocked, resulting in an increase in the resistance of the oil and gas side, thus affecting oil and gas recovery normal operation of the device

Abstract

The invention discloses an oil gas defrosting system and method for a condensation method oil gas recovery device. The oil gas recovery device comprises an oil gas inlet and an oil gas outlet and further comprises a heat exchange module installed between the oil gas inlet and the oil gas outlet and used for condensing oil gas, and the defrosting system comprises a heat exchange branch A and a heatexchange branch B which are arranged in the heat exchange module and connected in parallel. The oil gas defrosting system further comprises an induced draft fan, a heat exchanger, a defrosting inletvalve A, a defrosting inlet valve B, a defrosting outlet valve A and a defrosting outlet valve B. By means of branch switching, frosting of the heat exchanger is avoided, and normal operation of the recovery device is guaranteed.

Description

technical field [0001] The invention relates to an oil and gas defrosting system for an oil and gas recovery device, and also relates to a defrosting method based on the system. Background technique [0002] In the process of production, transportation and sales of petroleum and its products, some light liquid components will be vaporized, and if they are discharged into the atmosphere, they will cause loss of oil products, environmental hazards and potential safety hazards. In view of the importance of oil and gas recovery to production safety, energy conservation and emission reduction, and environmental protection, the Ministry of Environmental Protection has successively issued a series of oil and gas pollutant emission standards, and put forward specific requirements for oil and gas emission concentration and oil and gas treatment efficiency. [0003] Existing commonly used oil and gas treatment methods include adsorption method, absorption method, membrane separation m...
