Description
Technical field
The invention belongs to chemical industry, environmental technology field, relate to distillation desorb reaction tower, especially a kind of eddy flow distillation desorber and application.
Background technology
Research shows that the excessive emissions of carbon dioxide is the major reason that causes the environmental problems such as global warming.China is also increasingly strict to the control of CO2 emission.In many CO2 emissions source, the most concentrated with the carbon dioxide of burning and exhausting, and concentration is higher, more for the benefit of absorbs.
For the improvement of carbon dioxide, adopt at present more method, be that the carbon dioxide in combustion product gases is absorbed, then the absorption liquid of enrichment is resolved, by the higher carbon dioxide collection of purity, carry out corresponding after-treatment, reach the target of the comprehensive regulation.
The technological process of carbon dioxide absorption and desorb is technology ripe and that realize commercial Application, adopting MEA or MDEA is absorbent, in solution after absorption, contain the carbon dioxide of 20% left and right, claim that this solution is rich solution, rich solution is passed in stripping apparatus, distill desorb, isolate carbon dioxide, in solution under residue, gas concentration lwevel is 7% left and right, claims that this solution is lean solution.Lean solution passes in absorption equipment, as absorbent, recycles.
In whole flow process, distillation desorption process is the key that can this technology recycle absorbent, and the height of its desorption efficiency has directly affected the effect of absorption and the energy consumption of desorb height simultaneously, and different desorption methods has directly affected the cost of operation.Distillation desorption process is mainly to rely on steam to contact with liquid, and the heat of steam, by the material evaporation to be separated in solution, forms gaseous material and enters in follow-up flow process, to reach the object of solute and separated from solvent.Therefore, the power of the size of gas-liquid contact area, gas-liquid exchange has directly affected the efficiency of distillation desorb.
Distillation desorption apparatus is generally desorber, and conventional desorber form mainly contains packed tower and plate column at present, and plate column is divided into again sieve-plate tower, valve tray tower etc.Packed tower is to utilize the surface area of filler large, the principle that gas-liquid contact area is large realizes desorb, treat the stripping workshop filling surface of flowing through from top to bottom, steam flows through filler from bottom to top, and two media contacts at filling surface, realize still-process, its gas-liquid contact face is large, but its gas-liquid mass transfer intensity a little less than, cause packed tower volume huger, from great, and easily there is the problems such as obstruction in filler.Plate column is to utilize flow of solution through tray surfaces, through installing to strengthen gas-liquid mass transfer intensity on plate, thereby realizes the turriform of still-process, and multilayer column plate is wherein set, and template has multiple pattern optional.On column plate tower, height of liquid layer needs more strictly to control, and the situation of flooding easily occurs, and individual layer plate efficiency is lower, needs series connection to compare multilayer column plate and just can reach target efficiency.
Known according to the principle of existing distillation desorption apparatus, increase gas-liquid contact surface area or increase gas-liquid mass transfer intensity, can improve the effect of distillation desorb, improve desorption efficiency.
