Abstract

The invention discloses an indirect condensation type oil-gas recovery unit with a self-defrosting function. The unit comprises a primary direct-expansion type condensing system, a secondary indirectcondensing system, a third indirect condensing system and a waste cold recovery system connected through an oil-gas pipeline. By organically combining a direct-expansion type refrigerating technologywith an indirect condensing technology, secondary and third systems easy to be frozen and condensed have low voltage and oil deficient problems as a refrigerant migrates easily as the refrigerating and defrosting modes are switched. By adopting the indirect condensing technology, a refrigerant system of a compressor is in a single refrigerating cycle all the way, so that the problem that the refrigerant migrates is solved thoroughly, and therefore, the low voltage of the system and oil deficiency of the compressor are further solved, and the operating reliability of the condensing unit is improved greatly.

Description

technical field [0001] The invention relates to the technical field of industrial organic compound recovery equipment, in particular to an indirect condensation type oil and gas recovery unit with a self-defrosting function. Background technique [0002] Liquid oil will generate a large amount of harmful oil and gas in the storage of tank farms, oil production operations, and oil refinery processing. Substandard oil and gas will be released into the atmosphere, which will not only cause energy waste, but also pollute the environment, damage human health, and cause fire hazard. Under the national environmental protection strong pressure policy, the state and local governments have formulated mandatory standards requiring that oil and gas must be recovered in occasions with oil and gas emissions to ensure that the exhaust gas meets the standards. [0003] At present, the main methods of oil and gas recovery are absorption method, adsorption method, membrane separation method ...
