Description

technical field

[0001] The invention relates to the technical field of oil and gas recovery systems, in particular to an oil and gas recovery device with heat recovery condensation and temperature-swing-pressure-swing adsorption combined process. Background technique

[0002] To meet the oil and gas discharge standards stipulated by the state, oil and gas recovery and treatment devices must be installed to recover and process the light hydrocarbon components in oil and gas. The existing oil and gas treatment methods include condensation, absorption, adsorption and membrane methods. Among them, the condensation method can liquefy and recover most of the light hydrocarbon components in oil and gas, but to meet the increasingly stringent national and local emission standards, a high degree of cryogenic cooling is required, but this method will pay a large price for power consumption; and The activated carbon adsorption method can just complete the deep purification of the conde...
