Description
Technical field
The utility model relates to a kind of gas dehydration treatment unit, relates in particular to well head, does not build the natual gas dehydrate unit in places such as the gas gathering and transportation station of purifying processing device and associated gas treatment station.
Background technology
Sweet natural gas from the reservoir extraction generally all contains saturated steam, in the defeated process of collection, when temperature decline or pressure rising, water in the Sweet natural gas can be liquid phase and separate out, in pipeline and equipment, cause hydrops, not only increase flow pressure drop, even form slug flow, also can quicken in the Sweet natural gas acidic components the corrosion of pipeline and equipment.Liquid water not only can freeze in freezing point, and, even liquid water also can form the solid hydrate of ice and snow shapes with some components in the Sweet natural gas when temperature of Sweet natural gas was higher than the freezing point of water, can stop up pit shaft, valve, pipeline and equipment when serious, influence the normal operation of the steady air feed and the production equipment of gas pipe line.Therefore, must remove moisture wherein outward before the regulation and stipulation Sweet natural gas is defeated, make its water dew point be reduced to prescribed value or safety value.
At some well head Sweet natural gases and small-sized gas gathering and transportation station, because the tolerance of handling is smaller, available general facilities seldom, adopt dehydration of conventional dehydration technique such as triglycol absorption process and molecular sieve adsorption dehydration to cause to invest and running cost too high, technical uneconomical.
Summary of the invention
In view of existing in prior technology the problems referred to above, it is simple that the utility model aims to provide a kind of treatment scheme, do not have the general facilities requirement, the embrane method natual gas dehydrate unit that investment, occupation of land and working cost are low.
Technical solution of the present utility model is achieved in that
A kind of embrane method natual gas dehydrate unit is characterized in that comprising:
By strainer, well heater, the membrane separation apparatus that air delivering pipeline is connected in series successively, described membrane separation apparatus is held back side at its film and is connected with air delivering pipeline;
Also comprise the vacuum pump, water cooler, branch flow container, the natural gas engine that are connected in series in turn by pipeline in its membrane permeation side with described membrane separation apparatus, and generator and electrical control cubicles;
Flow container was sent gas-phase product into described natural gas engine at its top in described minute, the latter's power output shaft is connected with the power shaft of described vacuum pump, generator respectively by transmission mechanism, generator is connected by cable with electrical control cubicles, and electrical control cubicles is connected with consumer in the device by power switch and lead;
Flow container connected the waste water pipeline at its bottom liquid phases exit end in described minute;
Described natural gas engine tail gas outlet is connected with well heater through air delivering pipeline, and well heater also is connected with exhaust pipe.Natural gas engine tail gas is connected in series well heater by the road, then through the exhaust pipe emptying.
Compared with prior art, the utlity model has following beneficial effect:
(1) adopt the separatory membrane technology of selective permeation water vapour that Sweet natural gas is dewatered, investment, the working cost of whole device is low, occupation of land is little.
(2) be fuel as natural gas engine with the infiltration gas of film, gas engine is the drive source of vacuum pump and generator, all facilities all do not need external power supply as power, has solved the difficult problem that places such as well head do not have electric operation.Also solved simultaneously the problem that membrane permeate gas is utilized again.
(3) well heater before the membrane separation apparatus adopts natural gas engine tail gas as thermal source, need not to increase extra thermal source.
(4) do not need the scene that extra general facilities is provided.
(5) adopt air cooled chiller, solved the difficult problem of the anhydrous operations in place such as well head.
