According to the compound type plate absorption tower for alcohol amine natural gas desulfurization and decarbonization, provided by the utility model, by transforming the internal structure of the absorption tower, the compound type plate absorption tower can effectively realize the alcohol amine natural gas desulfurization and decarbonization and better defoaming performance; and simultaneously, the stability in operation of the absorption tower can be improved, and the working efficiency of the absorption tower can be ensured.
Description
Technical field
The utility model relates to the gas field purifying device for natural gas, the compound board-like absorption tower of particularly a kind of hydramine selexol process decarburization.
Background technology
In hydramine selexol process carbon rejection process, finish the mass transfer and the heat transfer process of Sweet natural gas and alkanolamine solution by the absorption tower, and then realize the desulfurization and decarburization of Sweet natural gas.In this mass-and heat-transfer process, influenced with solution composition by tray structure influences, and problems such as foaming inevitably take place alkanolamine solution, causes the liquid that blocks on absorption tower when serious.
At present, single tray column is all adopted on hydramine selexol process decarbonization device absorption tower, is mainly float valve type tray column.Be subjected to the float valve structure influence, the impurity such as solid particulate in the circulation amine liquid very easily stop up float valve, cause that the column plate differential pressure increases, and it is frequent that liquid is blocked on the absorption tower.The rich solution that has absorbed acid gas and part hydrocarbon gas simultaneously directly enters the downstream flash evaporation unit at the bottom of tower, especially the content fluctuation of hydrocarbon component is bigger to make gaseous fraction in the flash distillation solution, the fluctuation of flash distillation tolerance and pressure, cause the fluctuation of whole desulfurization unit system liquid level, the device fluctuation of service.
The utility model content
Technical problem to be solved in the utility model provides a kind of compound board-like absorption tower that can effectively realize decarburization of hydramine selexol process and resistance bubble better performances.
For solving the problems of the technologies described above, the utility model provides the compound board-like absorption tower of a kind of hydramine selexol process decarburization, comprise absorber tower cylinder, be arranged on two kinds of structure formations in the absorber tower cylinder tower tray, be installed in the filler of absorber tower cylinder bottom and be arranged on tower at the bottom of rich solution go out the isolated gate of Ta Kouchu.
Further, the described tower tray vertical sieve tray tower tray or the radial side that comprise the valve tray that is arranged on absorber tower cylinder top and be arranged on the absorber tower cylinder middle and lower part led jet tray.
The compound board-like absorption tower of a kind of hydramine selexol process decarburization that the utility model provides, by the absorption tower internal structure is transformed, can effectively realize the decarburization of hydramine selexol process, and resistance bubble better performances, simultaneously can also improve the operational stability on absorption tower, guarantee the absorption tower working efficiency.
Description of drawings
The structural representation on the compound board-like absorption tower of the hydramine selexol process decarburization that Fig. 1 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1, the compound board-like absorption tower of a kind of hydramine selexol process decarburization that the utility model embodiment provides, rich solution went out the isolated gate 5 at tower mouth 12 places at the bottom of vertical sieve tray tower tray 3 or the radial side that comprises absorber tower cylinder 1, is arranged on the valve tray 2 on absorber tower cylinder 1 top and is arranged on absorber tower cylinder 1 middle and lower part led jet tray 3, is filled in the filler 4 of absorber tower cylinder 1 bottom and is arranged on tower.Wherein, valve tray 2, vertical sieve tray tower tray 3 and radial side are led jet tray 3 and are included seal pot 6, overflow weir 7 and liquid discharging plate 8, and the upper portion side wall of absorber tower cylinder 1 is provided with lean solution tower entrance 9, lower sides and is provided with unstripped gas tower entrance 10, top and is provided with that wet purification gas goes out tower mouth 11, the bottom is provided with rich solution and goes out tower mouth 12 and sewage draining exit 13.
The compound board-like absorption tower of a kind of hydramine selexol process decarburization that the utility model provides, the bottom of adopting EA-3 conjugate ring filler 4 to load in the absorption tower, and rich solution goes out tower mouth 12 places isolated gate 5 is set at the bottom of tower, prevents that filler 4 flows out the absorption tower and blocking pipeline with rich solution in the solution circulated process.By filler 4 is set at the bottom of tower, the solution in the absorption tower goes out before the tower and in filler 4 contact processes, the hydrocarbon gas that carries in the solution is further separated, and makes flash distillation tolerance and system's liquid level maintain a stable range, improves system operation stability.
The middle and lower part that material stops up easily taking place in the absorption tower, adopt vertical sieve tray tower tray or radial side to fall jet tray 3, former valve tray column column plate is transformed, increase the mass transfer space, suppresses material and stop up.On the column plate, the membrane of gas and liquid, fragmentation, at most, return, to spray, separates 6 steps and in the solid space that column plate to cover pushes up, carries out, in this spatial dimension, gas is external phase, liquid is disperse phase---be tiny drop, liquid is supernatant liquid on the plate face, does not have foaming mechanism on the column plate, is particularly suitable for handling easy foamed material.
On relatively cleaner top, absorption tower, still adopt part valve tray 2, valve tray 2 keeps the number of plies can be regulated according to the efficient of acidic components characteristics and absorption tower absorption acidic components, general for the higher Sweet natural gas of carbon-sulfur ratio, the number of valve tray 2 should suitably increase, to improve column plate decarburization efficient.The principle of work of valve tray 2 is: liquid is by the liquid discharging plate 8 places inflow seal pot 6 of upper strata tower tray by the left side, transverse flow is crossed on the tower tray then, it is bubbling area herein, the bubble that is used for initial gross separation liquid simultaneously, liquid flow is crossed the liquid discharging plate 8 that overflow weir 7 enters the right side then, the vapor removal of being carried secretly in liquid discharging plate 8 comes out to rise and returns tower tray, clear liquid then flows to lower floor's seal pot 6, meanwhile, gas rises from valve opening, backs down valve block, passes annular backlash, blow to liquid layer with horizontal direction, form foam.Float valve is along with increase and decrease lifting in quite wide gas speed scope of gas speed, to keep stable operation.When hydramine lean solution temperature and viscosity are suitable, can obtain better mass-transfer efficiency.
The compound board-like absorption tower of a kind of hydramine selexol process decarburization that the utility model provides is by the improvement to the absorption tower internal structure, be applicable to composite board type absorption tower desulfurization and decarburization in the hydramine selexol process decarbonization process, can guarantee device steady running and good desulfurization and decarburization effect.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
