Abstract
The invention discloses a method for eliminating natural gas hydrate from a natural gas pipeline. The method comprises the following steps of: preparing a cylindrically-structured array carbon nanotube film, namely, selecting a substrate which is a substance attached onto the cylindrical array carbon nanotube film and may be a metal sheet, an aluminum sheet, a ceramic sheet and the like, putting the treated substrate into a quartz tube, taking FeC32N8H16 as a carbon source and ACROS as a catalyst, cracking for 15min by using a high-temperature tube furnace at the temperature of 900 DEG C in the flowing atmosphere of argon and hydrogen (in the volume ratio of 1:1), and thus obtaining the cylindrical array carbon nanotube film on the substrate; manufacturing a nano super hydrophobic material by using the cylindrical array carbon nanotube film; and coating the nano super hydrophobic material on the inner wall of the pipeline and the inner hole of a valve by a special process so as to prevent ice-like natural gas hydrate from forming and ensure the smoothness of a well hole and the pipeline.
Description
Affiliated technical field
The present invention relates to method of gas hydrate in a kind of elimination natural gas line.
Background technique
At present; In the process in producing oil gas field; Because the variation of temperature and pressure usually forms the gas hydrates of avenging shape in pit shaft or conveyance conduit, this gas hydrates can stop up pit shaft and pipeline; Have a strong impact on the normal operation of gas production and gas transmission work, strengthening the cost of manufacturing enterprise.
Summary of the invention
For overcoming under the existing situation, in the process in producing oil gas field, because the variation of temperature and pressure; Usually in pit shaft or conveyance conduit, form the gas hydrates of snow shape; This gas hydrates can stop up pit shaft and pipeline, are having a strong impact on the normal operation of gas production and gas transmission work, have strengthened the deficiency of the cost of manufacturing enterprise; The invention provides method of gas hydrate in a kind of elimination natural gas line; It can stop gas hydrates attached on the pipeline, prevents that gas hydrates from stopping up pit shaft and pipeline, reduced the cost of production of enterprise.
The technical solution adopted for the present invention to solve the technical problems is: produce column structure array carbon nano tube film earlier, method is to select substrate earlier; The material that substrate adheres to for the columnar arrays carbon nano-tube film can be tinsel, aluminium flake or ceramic plate etc., and the substrate after will handling is again put into quartz tube; (FeC32N8H16 is ACROS) as carbon source and catalyzer, in the mobile atmosphere of argon gas and hydrogen (volume ratio is 1: 1) with FePC; With high temperature process furnances at 900 ℃ of following cracking 15min; Can on substrate, obtain the columnar arrays carbon nano-tube film, make the nano superhydrophobic material with the columnar arrays carbon nano-tube film again, be coated in the place that forms gas hydrates in the pipeline easily to this nano superhydrophobic material with special process; Just can stop the formation of the gas hydrates of ice and snow shape, guarantee the unimpeded of pit shaft and pipeline.
The invention has the beneficial effects as follows, can stop gas hydrates to stop up pit shaft and pipeline, reduced the cost of production of enterprise.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the natural gas line organigram.
Fig. 2 is sectional view and the nano superhydrophobic material coating key plan of Fig. 1.
1. natural gas lines among the figure, 2. valve endoporus, 3. valve seat, 4. handle, 5. inner-walls of duct nano coating, 6. valve endoporus nano coating.
Embodiment
In Fig. 1, natural gas line has valve on (1), and handle (4) and valve seat (3) are arranged on the valve, and the center of valve is valve endoporus (2).
In Fig. 2, valve endoporus (2) is arranged on the natural gas line (1), produce column structure array carbon nano tube film earlier; Method is to select substrate, the material that substrate adheres to for the columnar arrays carbon nano-tube film earlier; Can be tinsel, aluminium flake or ceramic plate etc., the substrate after will handling be again put into quartz tube, with FePC (FeC32N8H16; ACROS) as carbon source and catalyzer, in the mobile atmosphere of argon gas and hydrogen (volume ratio is 1: 1), with high temperature process furnances at 900 ℃ of following cracking 15min; Can on substrate, obtain the columnar arrays carbon nano-tube film, make the nano superhydrophobic material with the columnar arrays carbon nano-tube film again, be coated in this nano superhydrophobic material on the inwall and valve endoporus (2) of natural gas line (1) with special process; So just formed inner-walls of duct nano coating (5) and valve endoporus nano coating (6); Owing to applied the nano superhydrophobic material, just can stop the formation of the gas hydrates of ice and snow shape, guarantee the unimpeded of pit shaft and pipeline.
