The utility model relates to the natural gas conditioning apparatus field, specifically a kind of Sweet natural gas degree of depth deacidifying device of skid-mounted.

Background technology

Natural gas liquids (LNG) is as the energy of a kind of cleaning, high-efficiency high-quality, China and even the fastest field of world energy supplies rate of growth have been become, LNG is except can be used on industrial fuel and industrial chemicals, can also make domestic fuel, especially in municipal gas distribution system as the means of peak regulation, can fully guarantee urban safety, air feed stably.

Comprise a large amount of scattered gas fields Sweet natural gas, gas field, border Sweet natural gas, associated gas and coal-seam gas etc. in China's natural gas upstream resource, for cost consideration, a lot of discomforts are built the transport pipe of long distance jointly, also discomfort is built fixed large-scale natural gas liquefying plant jointly, so should consider to build small-sized sledge dress natural gas liquefaction device.Compare with large-scale liquefying plant, small-sized sledge dress natural gas liquefaction device not only has raw material advantage, the market advantage, and invest low, can move, handiness is big, and very wide application prospect is arranged.Part as small-sized sledge dress natural gas liquefaction device, the Sweet natural gas degree of depth deacidifying device of front end also should be the sledge dressization, and can adapt to the variation of multiple source of the gas, but traditional hydramine absorption unit is difficult for into sledge and transportation, device according to the fixed gas source design, does not have enough suitabilities to multiple source of the gas yet.

Summary of the invention

Technical assignment of the present utility model is at above weak point, and a kind of fast, Sweet natural gas degree of depth deacidifying device fast, that transport convenient removal, adaptable a kind of skid-mounted of going into operation of installing is provided.

The technical scheme that its technical problem that solves the utility model adopts is: this deacidifying device comprises unstripped gas separator, pre-extracting tower, degree of depth extracting tower, purge gas separator, rich solution flash tank, poor rich liquid heat exchanger, lean solution water cooler, lean pump, amine liquid regenerator column, reboiler, carbon dioxide cooler, carbonic acid gas gas-liquid separator and reflux pump, it is characterized in that above-mentioned each device all is installed on the sledge piece base.

Described unstripped gas separator is communicated with pre-extracting tower, degree of depth extracting tower respectively by pipeline, and amine liquid regenerator column is communicated with pre-extracting tower, degree of depth extracting tower respectively by pipeline.

On described amine liquid regenerator column and the pipeline that pre-extracting tower, degree of depth extracting tower are communicated with poor rich liquid heat exchanger, lean solution water cooler and lean pump are installed successively.

The bottom of described amine liquid regenerator column is connected with reboiler.

On the pipeline between described pre-extracting tower and degree of depth extracting tower and the amine liquid regenerator column rich solution flash tank is installed.

The top of described degree of depth extracting tower is connected with purge gas separator by pipeline.

The top of described amine liquid regenerator column connects carbon dioxide cooler, carbonic acid gas gas-liquid separator and reflux pump successively by pipeline.

The Sweet natural gas degree of depth deacidifying device of a kind of skid-mounted of the present utility model is compared with prior art, has characteristics such as reasonable in design, that installation is fast, it is fast to go into operation, transport convenient removal, adaptability is strong.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The Sweet natural gas degree of depth deacidifying device of a kind of skid-mounted of the present utility model, its structure comprises unstripped gas separator 1, pre-extracting tower 2, degree of depth extracting tower 3, purge gas separator 4, rich solution flash tank 5, poor rich liquid heat exchanger 6, lean solution water cooler 7, lean pump 8, amine liquid regenerator column 9, reboiler 10, carbon dioxide cooler 11, carbonic acid gas gas-liquid separator 12 and reflux pump 13, and above-mentioned each device all is installed on the sledge piece base 14.

Unstripped gas separator 1 is communicated with pre-extracting tower 2, degree of depth extracting tower 3 respectively by pipeline, and amine liquid regenerator column 9 is communicated with pre-extracting tower 2, degree of depth extracting tower 3 respectively by pipeline; On amine liquid regenerator column 9 and the pipeline that pre-extracting tower 2, degree of depth extracting tower 3 are communicated with poor rich liquid heat exchanger 6, lean solution water cooler 7 and lean pump 8 are installed successively, on the pipeline between extracting tower 2 and degree of depth extracting tower 3 and the amine liquid regenerator column 9 rich solution flash tank 5 are installed also in advance in addition; The top of degree of depth extracting tower 3 is connected with purge gas separator 4 by pipeline; The bottom of amine liquid regenerator column 9 is connected with reboiler 10; The top of amine liquid regenerator column 9 connects carbon dioxide cooler 11, carbonic acid gas gas-liquid separator 12 and reflux pump 13 successively by pipeline.

When acid gas components content is at 20~10%V in the unstripped gas, be introduced into pre-extracting tower 2, unstripped gas is carried out pre-depickling handle, acid gas components is reduced to enters degree of depth extracting tower below 10% again; When acid gas components content in the unstripped gas when 10%V is following, then directly enter degree of depth extracting tower 3 and remove sour gas, its content is removed to≤50ppm, satisfy the natural gas liquefaction requirement.
