Description

The technology of absorbing and producing carbon dioxide by alcohol amine method
Affiliated technical field
The present invention relates to a kind of technology of extracting the collection production method, particularly a kind of absorbing and producing carbon dioxide by alcohol amine method of the carbon dioxide that discharges in the industrial processes, be suitable for collecting the production carbon dioxide.
Background technology
At present, the CO that discharges because of combustion of fossil fuels global every year 2Reach about 20,000,000,000 t, by the CO of fossil energy burning generation 2Total amount accounts for 82% of greenhouse gases total amount.Along with the concern of countries in the world to the global greenhouse effect problem, CO 2Reduce discharging and cause global attention day by day.Reclaim CO 2Be not only and alleviate CO 2The most direct effective means of discharging crisis can also reduce production costs, and owing to the demand of economic development to industrial carbon dioxide constantly increases, the method will be brought considerable economic.But it is not perfect to collect production technology, and problem is many, therefore, has brought bigger trouble to the user.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of technology of absorbing and producing carbon dioxide by alcohol amine method is provided.This technology not only technology is reasonable, and preparation is simple, and good product quality, and has solved problem of environmental pollution.
The technical solution used in the present invention is: cooling tower, blower fan, absorption tower, rich solution pump, 1# cooler, 1# container, regenerator, lean pump, 2# cooler, 3# cooler, reboiler, separator, underground tank, hydramine reclaim heater, filter is assembled into one by connecting line by its systemic-function and constitutes.
During use, the technology of the present invention device is connected in the CO2 emission commercial plant, the technology of the present invention device is that absorbability is strong, is suitable for from normal pressure and low CO 2Reclaim CO in the flue gas of content 2, control CO 2The saturated absorption amount is at 0.35mol CO 2In/mol the amine.A kind of hydramine method absorbs the technology that reclaims carbon dioxide, utilize carbon dioxide and a certain absorbent chemically reactive, generate intermediate compound, and other gases do not react with this absorbent, after decomposing, the intermediate compound that generates generates carbon dioxide and absorbent again in the another one device, absorbent is recycled, and carbon dioxide is discharged continuously, thereby makes carbon dioxide and other mixed gas separation.This method absorption process does not need to add high pressure or reduce temperature, and the selectivity height, and the gas concentration lwevel of discharge can reach more than 98%, and the desorb carbon dioxide needs Steam Heating from middle compound.Water and flue gas are through the cooling tower collection and treatment, with blower fan intermediate compound is squeezed into the absorption tower, through Steam Heating, carbon dioxide gas goes out the rich solution on absorption tower and squeezes into regenerator with the rich solution pump, lean solution after the regeneration is squeezed into the absorption tower again with lean pump and is continued to repeat to synthesize, then, through the operation operation of each program element, reclaim and produce the carbon dioxide finished product.
The invention has the beneficial effects as follows, reasonable in design, easy to use, be that desirable carbon dioxide recovery prepares production Technology.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Accompanying drawing number is: 1, cooling tower, 2, blower fan, 3, the absorption tower, 4, rich solution pump, 5, the 1# cooler, 6, heat exchanger, 7, regenerator, 8, lean pump, 9, the 2# cooler, 10,3# cooler, 11, reboiler, 12, separator, 13, underground tank, 14, hydramine reclaims heater, and 15, filter, 16, connecting line.
The specific embodiment
With reference to Fig. 1, cooling tower (1), blower fan (2), absorption tower (3), rich solution pump (4), 1# cooler (5), 1# container (6), regenerator (7), lean pump (8), 2# cooler (9), 3# cooler (10), reboiler (11), separator (12), underground tank (13), hydramine reclaim heater (14), filter (15) is assembled into one by connecting line (16) by its systemic-function and constitutes.
During use, the technology of the present invention device is connected in the CO2 emission commercial plant, the technology of the present invention device is that absorbability is strong, is suitable for from normal pressure and low CO 2Reclaim CO in the flue gas of content 2, control CO 2The saturated absorption amount is at 0.35mol CO 2In/mol the amine.A kind of hydramine method absorbs the technology that reclaims carbon dioxide, utilize carbon dioxide and a certain absorbent chemically reactive, generate intermediate compound, and other gases do not react with this absorbent, after decomposing, the intermediate compound that generates generates carbon dioxide and absorbent again in the another one device, absorbent is recycled, and carbon dioxide is discharged continuously, thereby makes carbon dioxide and other mixed gas separation.This method absorption process does not need to add high pressure or reduce temperature, and the selectivity height, and the gas concentration lwevel of discharge can reach more than 98%, and the desorb carbon dioxide needs Steam Heating from middle compound.Water and flue gas are through cooling tower (1) collection and treatment, with blower fan (2) intermediate compound is squeezed into absorption tower (3), through Steam Heating, carbon dioxide gas goes out the rich solution on absorption tower (3) and squeezes into regenerator (7) with rich solution pump (4), lean solution after the regeneration is squeezed into absorption tower (3) again with lean pump (8) and is repeated to synthesize, then, through the operation operation of each program element, reclaim and produce the carbon dioxide finished product.
