Technical field
The utility model relates to natural gas extraction technical field more particularly to a kind of natural gases with nanometer dry film
Dehydration device and Gas Dehydration System.
Background technique
Oil and gas is energy form important in the world, is the blood of All Around The World industrial activity.Natural gas is made
Grow steadily for maximally efficient, clean fuel and industrial chemicals, the status in world's energy resource structure in the world.Natural gas is
A kind of fossil fuel is mainly made of the mixing of all kinds of alkane, furthermore usually also contains hydrogen sulfide (H2S), carbon dioxide (CO2), water
With the impurity such as organic sulfur compound.H2S and CO2There is extremely strong corrosivity to equipment and gathering line, especially when depositing in natural gas
In saturated water, this process will be aggravated.However, the wet purification after raw natural gas mined in stratum and desulfurization (carbon)
Natural gas generally all contains saturated water, and main harm is as follows:
(1) presence of saturated water will increase gas flow pressure drop, decline the conveying capacity of gas pipeline, increase gas transmission
Cost；The calorific value of natural gas, which can also be made, to be reduced.
(2) under the action of high pressure or low temperature, saturated water can be precipitated from air-flow becomes liquid water.Liquid water will and air-flow
In other substances such as hydro carbons, acidic components be formed together the hydrate as ice, increase gas transmission pressure drop, reduce appendix
The handling capacity in road can also block pipeline or other process equipments when serious, impact to gas transmission gas supply.
(3) when liquid water and H2S、CO2After equal acidic components mixing, acid solution is formed, tube wall, pipe valve can be generated
Corrosiveness reduces the service life of pipeline.
Therefore, carrying out dehydration to natural gas before natural gas transportation seems particularly significant.It is stored up to reduce moisture in natural gas
It deposits and security risk possible in transmission process, it is necessary to which it is carried out dehydrating.Dewatered natural gas reaches regulation
Water-content indicator after, just allow access into Trunk-line.
