Description
Technical field
The present invention relates to a kind of method of resolving synthetic-ammonia transformation gas decarbonization absorbent rich solution, also relate to the application of high-gravity technology in the absorbent rich solution is resolved.
Background technology
In the Ammonia Production technical process, two sections reformed gas of natural gas, CO after pyrolytic conversion
2Content is up to 18~19%, because CO
2Can make catalyst poisoning, so conversion gas must be removed thoroughly before entering synthesis loop; CO in addition
2Be again the raw material of urea plant, must be reclaimed CO
2Remove and reclaim the Carbon balance that is directly connected to the ammonia synthesis process system, therefore, CO
2Remove and reclaim most important.Decarburization energy consumption accounts for about 10% of whole ammonia energy consumption, therefore removes CO
2The energy consumption height of technology is very big to the influence of ammonia factory total energy consumption.
The method of present industrial parsing decarburization rich solution is a lot, but principle is all identical, mainly slightly different because of the difference of absorption process, all be to be mass transfer apparatus with the regenerator, low-pressure steam enters from the bottom of tower, and rich solution enters from cat head, gas-liquid is counter current contacting in packing layer, and then reach the purpose of regeneration. still, no matter adopt any method decarburization, the mass-transfer efficiency of tower equipment directly affects and absorbs CO
2After the internal circulating load and the CO of rich solution
2Reclaim, also just affect the regeneration cost of decarbonizing process.The efficient height of resolver, the internal circulating load of rich solution are with regard to corresponding minimizing, and the regeneration load reduces simultaneously, thereby has saved the energy, has reduced the cost of regenerative process.Therefore, the mass-transfer efficiency of raising analyzing device is the most direct valid approach that reduces cost, increases economic efficiency.
In the legacy equipment between the vapour-liquid power resources of reverse contact be gravitational field.Because of gravity acceleration value limited (9.8m/s2), cause the dirty speed of liquid slower, for preventing liquid flooding and serious entrainment, the vapour phase rate of climb is also little, so relative velocity is less between the two-phase, and mass transfer effect is not good.
High-gravity technology is a new technology of utilizing the hypergravity environment more much bigger than terrestrial gravitation acceleration that mass transfer, diabatic process and micro mixing are strengthened, produces the hypergravity environment of simulating by rotation on earth and obtains.It can increase substantially the conversion ratio and the selectivity of reaction, dwindles the volume of reactor significantly, simplifies technology, flow process, and implementation procedure energy-efficient reduces disposal of pollutants.Research and analysis show, under the hypergravity environment, molecular diffusion between different sized molecules and interphase mass transfer process are all than in after the match faster of terrestrial gravitation, produce the contact of flowing in gas one liquid, liquid-liquid, the liquid one solid porous media of two-phase under the hypergravity environment bigger hundreds of times to thousand times than earth gravitational field, great shear forces makes liquid crushing become nano level film, silk and drips, produce boundary huge and that upgrade fast, make and improve 1~3 order of magnitude in the traditional tower of interphase mass transfer speed ratio, mass transport process is greatly strengthened.
Aspect the energy-conservation regeneration techniques of exploitation new technological process, Uop Inc. early develops steam jet ejector flash regeneration lean solution technology, pressure swing regeneration power-saving technology in recent years and towers regeneration technology, and isolate steam in the regeneration gas and other condensable gas with membrane separating method, will return regenerator as thermal source after its compression.
Aspect the high-gravity technology decarburization, U.S. FlourDaniel company is to H
2S and CO
2Selectivity absorbs to be studied, and utilizes the difference of two component reaction rates, has reached better separating effect.Domestic the most representative is Beijing University of Chemical Technology aspect the high-gravity technology research and development, has carried out a series of innovative research work.At first hypergravity water deoxygenation technology was realized industrial applications in the world in 1998; Cooperated with U.S. DOW chemical company in 1999, and successfully high-gravity technology was applied to the gas liquid reaction separation process in the chlorine industry.And adopt high-gravity technology to resolve the research that synthetic ammonia process purifies the rich solution in the part solution recycle system, be not reported so far both at home and abroad.

Embodiment 2-5
Remove the gas liquid ratio in the Change Example 1, all the other are by example 1 conditional operation, and experimental result sees Table 2.
The different gas liquid ratio regeneration test of table 2 result
As can be seen from Table 2, along with reducing gradually of gas liquid ratio, KHCO3 concentration raises gradually in the regeneration lean solution, that is to say, the regeneration of absorbent rich solution is more and more not thorough.At steam/rich solution mass ratio is 1: when (25~50), and KHCO in the lean solution
3Concentration can be reduced to below 10%.Compare with tower equipment, under the equal conditions, reach same parsing effect, tower equipment steam/rich solution mass ratio is generally 1: (18~30), hypergravity equipment steam consumption is compared with tower equipment, obviously reduces.
Embodiment 6-9
Adopt the method for example 1, change regeneration temperature, all the other are by example 1 conditional operation, and experimental result sees Table 3.
Table 3 different temperatures regeneration test result
As can be seen from Table 3, along with the rising of temperature, KHCO3 concentration descends gradually in the solution, that is to say that the resolution ratio of KHCO3 improves; When reaction temperature reaches after 120 ℃, curve tends to be steady, and absorbent KHCO3 content is reduced to below 10%, has been lower than the tower regeneration lean solution KHCO3 of factory content (the tower regeneration lean solution KHCO3 of factory content 11%~12%), consider that from energy-saving and cost-reducing angle suitable reaction temperature is 120 ℃.

3Concentration, reduce, but when rotor speed is higher than 1200r/min KHCO in the solution gradually with the increase of rotating speed
3Concentration begins to increase.Analyze its reason, because the revolution of rotor is high more, the size of liquid film, brin and the drop that can cut into liquid becomes littler, and the heat absorption effect can be more better, is beneficial to the carrying out of decomposition reaction; But, when rotating speed surpasses 1200r/min, can cause Partial K HCO because the height of rotating speed can influence the time of staying of material in reactor
3Do not have enough time to decompose and just thrown away packing layer, cause KHCO by rotor
3Decomposition efficiency reduces.Relatively Shi Yi rotor speed is 1200r/min.
