Embodiment
[0027] The natural gas enters from the transmission pipeline 1, is pretreated through the pretreatment pipeline 6, and flows out from the transmission pipeline 1 at the other end.
[0028] The fixed pipe 17 and the flexible pipe 15 are respectively screw-fixed at both ends of the double-way pipe 16 , and the diameter of the flexible pipe 15 is 1 / 2 of the diameter of the fixed pipe 17 .
[0029] The mercury removal tray 18 and the drying tray 19 are arranged at intervals, which improves the purification efficiency of natural gas.
[0030] The diameter of the ventilation holes 20 is 2-3 mm, and the drying tray 19 is filled with a regenerated mercury adsorbent, specifically HgSIV.
[0031] The regenerated mercury sorbent HgSIV can play the dual role of mercury removal and drying.
[0032] Described mercury removal plate 18 is provided with several mercury adsorption plates 21, and described mercury adsorption plate 21 is welded on the inner side wall of described mercury removal...

Abstract
The invention discloses a natural gas liquefaction, separating and pretreatment technology. The natural gas liquefaction, separating and pretreatment technology comprises conveying pipelines, connection plates are arranged at an outer rim of two ends of the conveying pipeline, bolt apertures are arranged at the connection plate, bolt studs are fixed at the bolt apertures, a protecting pipeline anda pretreatment pipeline are arranged between two conveying pipelines, the pretreatment pipeline is spirally fixed between two conveying pipelines, the pretreatment pipeline is sleeved in the protecting pipeline, and the protecting tube is fixed between two connection plates. According to the disclosed natural gas liquefaction, separating and pretreatment technology, through pretreatment simplification operation and reduction of a volume of pretreatment equipment, the natural gas liquefaction, separating and pretreatment technology is suitable for low-flow natural gas, and increases the mercury-removal efficiency.
Description
technical field [0001] The invention relates to a natural gas liquefaction separation treatment, in particular to a natural gas liquefaction separation pretreatment device, which belongs to the application field of natural gas liquefaction equipment. Background technique [0002] Natural gas liquefaction mainly includes natural gas pretreatment process and natural gas liquefaction process. The natural gas from the pipeline network must be pretreated and purified before liquefaction, including drying, mercury removal, etc., to prevent these impurities from freezing at low temperatures and causing blockage and corrosion. equipment and piping. [0003] The existing natural gas liquefaction pretreatment equipment has a large volume and is not suitable for low-flow natural gas liquefaction pretreatment processes. Contents of the invention [0004] The object of the present invention is to provide a natural gas liquefaction separation pretreatment device in order to solve the a...
