Description
The invention belongs to a coke oven gas desulfurization solution and application thereof, and particularly relates to a cobalt phthalocyanine sulfonate (PDS for short) desulfurization solution and application thereof.
At present, the desulfurization of coke oven gas in the world is widely carried out by an improved A, D, A method, and the desulfurization solution comprises the following components:
Na2CO30.1—0.2N，NaHCO30.3—0.4N，
A. d, A3.5.5 g/l, NaVO32 g/l of the total amount of the active ingredients,
NaKC4H4O61 g/l. The desulfurization process comprises the following steps:
(1) the coal gas is in countercurrent contact with the desulfurization solution, and the PH value of the desulfurization solution is 8.5-9.0;
(2) the pressure of coal gas entering the tower is about 600 mm/water column, and the temperature is 25-30 ℃;
the pressure of the coal gas discharged from the tower is about 450 mm/water column, and the temperature is 35-40 ℃;
(3) the empty speed of the gas in the desulfurizing tower is 0.5-0.75 m/s, and the liquid-gas ratio is more than 16L/standard meter3Spray density>27.5 m3Rice/rice2When the regeneration tower is used, the solution stays for 25-30 minutes, and the consumption of the regeneration air is 9-13 meters3One kilogram of sulfur and the blowing intensity of the regenerated air is more than 60 meters3Rice/rice2Then (c) is performed. [1]The desulfurization solution has a higher sulfur capacity, thus allowing the absorption operation to be carried out with more hydrosulfide in the solution，[2]Because sodium vanadate and sodium hydrosulfide react quickly, the alkalinity of the solution can be lower, thus reducing the speed of generating sodium thiosulfate under a certain concentration of hydrosulfide, [3]]Most of the reaction process of absorbing hydrosulfide by solution and separating out sulfur occurs in the desulfurizing tower, and the mass transfer coefficient is also larger. However, this method [1]]There is a side reaction which is a side reaction, 、 ， ， sodium bicarbonate is generated in the process of absorbing hydrogen sulfide, hydrogen cyanide and carbon dioxide, has much lower solubility than sodium carbonate, and is easy to precipitate. [2]Easy corrosion, toxicity and high cost. [3]The primary desulfurization can not stably reach the quality standard of the urban gas. [4]The removal cost of the secondary reaction products in the mother liquor is high, and the environmental pollution is caused.
The invention aims to provide the cobalt phthalocyanine sulfonate desulfurizing liquid which has low desulfurizing cost, simple desulfurizing process, no corrosion, no blockage, no toxicity, low cost for removing side reaction products in liquid after desulfurization and no environmental pollution, can be used for achieving the quality standard of urban coal gas by one-time desulfurization, and the desulfurizing process of the cobalt phthalocyanine sulfonate desulfurizing liquid in coke oven gas.
In order to achieve the purpose, the cobalt phthalocyanine sulfonate doctor solution comprises the following components in percentage by weight:
sodium carbonate 2.0-3.5 g/l sodium bicarbonate 5.0-10.0 g/l
PDS 0.5-25 PPM (weight)
The PDS desulfurizing liquid of the present invention may also contain quinone assistant in 0.05-0.29 g/L.
The PDS desulfurization solution preferably further contains 40 to 60 mg/L of a divalent metal ion.
The PDS desulfurization solution of the invention has quinone additives such as benzoquinone, anthraquinone and the like.
The PDS desulfurization solution of the invention has Fe as the divalent metal ion++、Mg++And the like.
The pH value of the PDS desulfurizing liquid is 8.0-8.7.
The preparation method of the desulfurization solution comprises the following steps: weighing the components according to the above amount, dissolving with a small amount of water, mixing, and diluting with water to the above concentration.
In order to achieve the purpose, the desulfurization process comprises the following steps:
1. the solution temperature of the desulfurization solution is 30-50 ℃;
2. the gas temperature is controlled at 25-30 ℃, and the gas and the liquid are in reverse contact.
3. The content of imported hydrogen sulfide is less than 3.5 g/standard meter3The content of hydrogen sulfide at the outlet is 20 mm/standard meter3In the following, the continuous addition method is adopted to control the concentration of PDS in the desulfurizing liquid to be 0.5-1.5 PPM (weight). The content of imported hydrogen sulfide is mixed with 3.5 g/standard meter3The content of hydrogen sulfide at the outlet is 20 mg/standard meter3In the following, the continuous addition method of PDS is used to control the concentration of PDS in the desulfurizing liquid to 1.5-2.5 PPM (weight).
4. The gas ratio of the desulfurization liquid to the coal gas is 25-36L/standard meter3When in use, the spraying density is 28-32 m3Rice/rice2Then (c) is performed.
The invention adopts PDS desulfurizing liquid.
1. The ADA, vanadium pentoxide and potassium sodium saccharate in the ADA method are omitted, so the cost is low, and the cost is only 30-40% of that in the ADA method.
2. The oxidation speed is high, so that sulfur foams are more, the required regeneration air quantity is correspondingly reduced by 30-40%, and the reaction process is as follows:
3. besides the general chemical adsorption, the catalyst also has the catalytic chemical absorption function, and the principle is as follows:
NaHS＋NaHCO3＋(x－1)S→Na2Sx＋CO2＋H2o (3) wherein (1) and (2) are chemical absorption, and (3) is a catalytic chemical absorption reaction specific to PDS. Thus, the desulfurization solution of the present invention has a high sulfur capacity, thereby allowing the absorption operation to be carried out in the presence of lower hydrosulfide in the solution.
4. The pH value of the solution can be controlled at a lower value, the absorption of the desulfurization solution to the hydrosulfide is not influenced, side reactions can be reduced, and the precipitation of sodium bicarbonate is reduced. In addition, the pH value of the desulfurization solution is low, so that the corrosion to equipment can be reduced, and the generation speed of sodium thiosulfate can be reduced.
5. The problem of cyanide poisoning is solved, the removal efficiency of the cyanide in the coal gas is up to more than 95%, and the reaction process is as follows:
6. side reaction is reduced, after the equilibrium is reached, the side reaction is basically not generated, and the desulfurization efficiency is not highAnd the yield of the sulfur is increased, and the alkali consumption is reduced. Thus, Na2s2O3Is actually consumed.
Due to NaSCN and Na2S2O3Is actually consumed in the reaction process, and avoids NaSCN and Na in the factor circulation process2S2O3The accumulation of (b) causes a problem of lowering the desulfurization efficiency.
7. Because the PDS desulfurization solution is adopted in the invention, sodium bicarbonate is not separated out or is less separated out after the desulfurization solution absorbs sulfide, therebyThe decarbonization treatment can be carried out without adding equipment to extract part of the solution. As the invention adopts PDS desulfurization solution, NaSCN and Na are added in the solution circulation process2S2O3Is actually consumed without having to draw solution to extract the crude baking soda and crude sodium hydrosulphate, thereby simplifying the process of the invention.
8. The continuous addition method of PDS can ensure the PDS concentration in the desulfurizing liquid to be 0.5-2.5PPM, and this can stabilize the desulfurizing rate.
