A kind of water washing liquid for primary treatment of exhaust gas in refinery

Abstract

The invention discloses washing liquor for refinery waste gas primary treatment, and relates to the technical field of waste gas treatment. The washing liquor is prepared from, by weight, 15-20 parts of fumed silica, 10-15 parts of nanometer montmorillonite powder, 10-15 parts of polyaluminum chloride, 8-12 parts of sodium carboxymethyl cellulose, 6-10 parts of molecular sieve raw powder, 6-10 parts of polyoxyethylene lauryl ether, 5-8 parts of silica-gel powder, 5-8 parts of ferric sulfate, 4-6 parts of glucoside, 4-6 parts of polyacrylamide, 3-5 parts of calcium stearate, 2-4 parts of sodium silicate, 1-2 parts of urea, 100-150 parts of n-butanol and 800-1,000 parts of water. According to the washing liquor for the refinery waste gas primary treatment, by means of flocculation and adsorption principles, partial organic matter in waste gas is removed to the maximum extent, the purpose of primary treatment is achieved, and therefore aftertreatment difficulty and aftertreatment cost are reduced.

Description

Technical field: [0001] The invention relates to the technical field of waste gas treatment, in particular to a water washing liquid for primary treatment of waste gas in a refinery. Background technique: [0002] Refinery exhaust gas is mainly discharged from heating furnaces and chimneys, as well as the exhaust gas discharged by heating and burning fuel through oil refining. The main pollutants are nitrogen oxides and sulfur dioxide. If the exhaust gas is directly discharged into the air, it will directly affect the air quality and pollute the environment. Therefore, in recent years, the treatment and emission standards for the refinery exhaust gas have become stricter. At present, there are many treatment methods for refinery exhaust gas, but most of them have the problems of complicated treatment steps and poor treatment process stability, resulting in different component content of the final treatment exhaust gas, and even some of the exhaust gas cannot meet the emission sta...

Problems solved by technology

At present, there are many treatment methods for refinery waste gas, but most of them have the problems of complicated treatment steps and poor stability of the treatment process, resulting in different component contents of the exhaust gas after final treatment, and even some of them fail to meet the emission standards and need to be treated again, thereby increasing the treatment cost.
