Description
Technical field
The invention belongs to chemical industry, environmental technology field, relate to distillation desorb reaction tower, especially a kind of filler eddy flow composite steam stripping tower and application.
Background technology
Research shows, the excessive emissions of carbon dioxide, is the major reason causing the environmental problems such as global warming.China is also increasingly strict to the control of CO2 emission.In many CO2 emission sources, 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, adopting more method at present, is absorb the carbon dioxide in combustion product gases, then the absorbing liquid of enrichment is resolved, by carbon dioxide collection higher for purity, carry out corresponding after-treatment, reach the target of the comprehensive regulation.
The technological process of carbon dioxide absorption and desorb is ripe and realizes the technology of commercial Application, employing MEA or MDEA is absorbent, containing the carbon dioxide of about 20% in solution after absorption, this solution is claimed to be rich solution, rich solution is passed in stripping apparatus, carry out distillation desorb, isolate carbon dioxide, in solution under residue, gas concentration lwevel is about 7%, claims this solution to be lean solution.Lean solution passes in absorption equipment, recycles as absorbent.
In whole flow process, distillation desorption process is the key that can this technology recycle absorbent, and the height of its desorption efficiency directly affects the effect of absorption and the energy consumption height of desorb simultaneously, and different desorption methods directly affects the cost of operation.Distillation desorption process mainly relies on steam and liquid comes into contact, 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 size of gas liquid interfacial area, the power of gas-liquid exchange directly affects the efficiency of distillation desorb.
Stripper form conventional at present mainly contains plate column and packed tower, and plate column is divided into again sieve-plate tower, valve tray tower etc.Packed tower utilizes the surface area of filler large, and the principle that gas liquid interfacial area is large realizes desorb, treats that desorb is held liquid and flowed through filling surface from top to bottom, steam flows through filler from bottom to top, two media contacts at filling surface, realizes stripping process, and its gas-liquid contact face is large, but its gas-liquid mass transfer intensity is more weak, cause packed tower volume huger, from great, filler easily blocks, opereating specification is little, and complex structure.Plate column utilizes solution to flow through tray surfaces, and on plate, device is to strengthen gas-liquid mass transfer intensity, thus realizes the turriform of still-process, wherein arranges multilayer column plate, 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 and resistance is larger.
According to the principle of existing stripper plant, increase gas-liquid contact surface area or increase gas-liquid mass transfer intensity, the effect of distillation desorb can be improved, improving desorption efficiency.
By retrieval, not yet find the patent publication us relevant to patent application of the present invention.
