Description
Technical field
This utility model belongs to Petro-Chemical Machinery, specifically extracts light oil from natural gas, relates to a kind of natural gas
Petroleum vapor recovery light oil device.
Background technology
Oil field region, gas delivering pipe net, the natural gas discharged by well head all contains substantial amounts of light oil, if not
Reclaim, natural gas will be had a strong impact on and carry gentle Geological Problems, as long as the clean gas after Hui Shouing, be just conducive to environmental protection.China is the most all
Being large-scale fixed, PROCESS FOR TREATMENT mode is aging, and floor space is big, and energy consumption is big, expensive, and investment is big, and is unsuitable for resettlement, in
Small business cannot use again.As few because of tolerance in current field area, pressure is little, it is impossible to input pipe network, only emptying are burnt, therefore
Torch gas firing is found everywhere, and not only wastes resource but also causes environmental pollution, the most unfortunately.
Petroleum collection, transport and store during, be required for using various tun that crude oil is loaded.For
Various tuns, for safety and the consideration of stress, all can only use normal pressure to store, and make tun communicate with the external world,
To keep the pressure reduction inside and outside storage tank substantially zeroed.But owing to there being multiple hydrocarbon component in crude oil, when storing, there is quite a few
Light oil evaporates from crude oil, for keeping pressure of storage tank not increase, it is necessary to discharge it into air.Based on crude character and collection
The difference of defeated flow process, this waste be from ten thousand/to one of percentage.This not only causes waste, and pollutes ring
Border.Big tank air extractor is used to solve this problem now with individual other oil storage tank.But owing to equipment is complicated, operation requires height,
Management controls difficulty, uses few in practice.Due to the development of petrochemical industry, the commodity value of lighter hydrocarbons carries increasingly in recent years
Height, reclaiming lighter hydrocarbons from big tank will put on the agenda.
In order to improve emptying waste, domestic primarily now have two ways.(1) domestic existing large-scale technical matters, need to have
Substantial amounts of source of the gas, such as collection transmission pipe network, large-scale gas station, it is necessary to have high tower edema caused by disorder of QI, uses light gas to rise, and the principle that heavily gas falls is divided
From natural gas, again must the equipment such as supporting boiler, molecular sieve dehydration, but the few region of tolerance is difficult to use.(2) domestic another kind
Technology, can separate without high tower, boiler is dried, molecular sieve dehydration, but must use substantial amounts of industrial chemicals, as antifreezing agent it
The compound of class, such as industrial methanol etc., has corrosiveness in various degree to steel metal, and the quality of oil is brought very big shadow
Ringing, light oil contains these chemical agents, and the color of oil there will be change, muddiness, has viscous thing floating, and these unfavorable factors are to oil
Selling price impact greatly, too increases energy consumption and cost simultaneously.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of light oil recovery devices from natural gas, this device
