Condensing and membrane separation combined type oil gas reclaiming technical technology

Abstract

The invention relates to a condensation and film separation combination type oil gas recycling art technique which is an improvement of condensation type oil gas art technique. The invention adopts the combined method of condensation technique and film separating technique to reach discharging standards. The problem that the temperature of single condensation type oil gas recycling reaches lowers than 95 DEG C below zero is overcome. The invention belongs to the oil gas recycling technical field, and is mainly used for the oil gas recycling of oil house, city transfer oil house, gasoline and light weight oil loading and unloading process. The invention consists of a refrigeration machine set 16, a pre-cooling box 2, a middle cooling box 3, a liquid ring type compressor 4, a switch 5, a membrane module 6, a vacuum pump 15, a switch 8, a switch 9, an oil water separator 10 and an oil pump 13. According to the art flow sequence in the attached drawing 1, the refrigeration machine set 16, the pre-cooling box 2, the middle cooling box 3, the liquid ring type compressor 4, the switch 5, the membrane module 6, the vacuum pump 15, the switch 8, the switch 9, the oil water separator 10 and the oil pump 13 are connected together and are arranged on a base crowing. The construction is shown in the attached drawing 2. The three-dimensional graph of the modular structure is shown in the attached drawing 2.

Description

technical field [0001] The invention is a new type of oil and gas recovery technology which integrates the respective advantages of the condensing oil gas recovery technology and the membrane separation type oil gas recovery technology, and belongs to the technical field of oil gas recovery. Background technique [0002] According to the research report of Sinopec Fushun Research Institute, in 2004, only gasoline loading and unloading in the whole country was counted, and the loss of oil and gas reached more than 500,000 tons a year. Not only wasting oil resources but also polluting the environment, for this reason the country began to formulate relevant emission standards (draft). The standard (draft) requires an annual turnover of 50,000 m 3 The above oil depots must be equipped with oil and gas recovery equipment. [0003] Oil and gas recovery technology currently has a variety of technical solutions, such as heavy oil absorption, activated carbon adsorption, condensati...
