Description
Technical Field
The invention relates to the technical field of flue gas desulfurization, in particular to a method for predicting sulfur content in coke oven gas.
Background
At present, the sulfur dioxide emission of heat treatment furnaces such as heating furnaces and the like is definitely required to be not more than 50mg/m 3 in China; for kilns using only mixed gas or coke oven gas as fuel, the sulfur dioxide content is only related to the sulfur elements in the fuel. The coke oven gas contains not only hydrogen sulfide but also organic sulfur such as carbon disulfide, carbonyl sulfide, methyl mercaptan and the like, and the organic sulfur can generate sulfur dioxide after combustion. Some enterprises are provided with hydrogen sulfide detection equipment aiming at the flue gas, and can also remove hydrogen sulfide in the flue gas, so that the hydrogen sulfide can be removed from 3-6 g/m 3 to below 200mg/m 3, even below 20mg/m 3. However, the method generally has no detection means and no danger escaping means for the organic sulfur in the coke oven gas, and along with the increasingly strict environmental protection requirements, the content of the organic sulfur has influenced whether downstream users can realize up-to-standard emission.
The Chinese patent application with publication number of CN110554136A discloses a method for detecting the sulfur content in blast furnace gas, which mainly solves the technical problem that the sulfur content in the existing blast furnace gas cannot be accurately detected. The method comprises the following steps of sampling; the method comprises the steps of burning a sample, transferring the blast furnace gas sample into a combustion tube for burning, controlling the temperature of the combustion tube to be 800-900 ℃ and simultaneously introducing oxygen and hydrogen into the combustion tube in the combustion process of the blast furnace gas, wherein the oxygen flow is 1.0-2.0L/min and the hydrogen flow is 2.0-3.0L/min; detecting a fluorescence integral response value of sulfur in the sample; and calculating the mass content of sulfur in the blast furnace gas. The technical scheme mainly realizes accurate determination of the sulfur content in the blast furnace gas, is simple and convenient to operate, has low detection cost, and is suitable for detecting the sulfur content in the blast furnace gas, the coke oven gas and the converter gas.
The Chinese patent application with publication number CN110849984A discloses a method for detecting sulfide in industrial gas, firstly, a microsyringe is used for extracting sample gas in the industrial gas and discharging the sample gas, after repeating the steps for 2 to 3 times, 100 to 200ml of gas to be detected containing sulfide is extracted, and then an autosampler is used for constant-speed sample injection; in the process, high-purity nitrogen is used as carrier gas, gas to be detected containing sulfide is carried, the gas is separated by chromatographic columns filled with stationary phase under certain chromatographic conditions, then the gas is measured by a flame photometry detector, the corresponding gas chromatograph obtained by the flame photometry detector is recorded by a computer, the retention time of chromatographic peaks is used for qualitative analysis, and the area of the chromatographic peaks is used for quantitative analysis. The method can accurately detect the components and the content of sulfide in the industrial gas, thereby realizing the purposes of energy conservation and emission reduction by continuously monitoring and improving. The technical scheme can analyze total sulfur in the coal gas, and the main method is that the coal gas is combusted in high-purity hydrogen, sulfide after combustion completely produces hydrogen sulfide, and then the hydrogen sulfide is detected by a chromatographic method.
The Chinese patent application with publication number of CN108490148A discloses an on-line detection device and a detection method for total sulfur content in fuel gas, wherein the on-line detection device comprises a combustion reaction furnace, an on-line gas flue gas detection system and a data acquisition and processing system; can accurately and timely guide the production of the gas desulfurization process and guide the production control of fuel. The technical scheme is that a certain amount of coke oven gas is oxidized and combusted in a combustion reaction furnace, and the total sulfur content in the gas is calculated through the amount of generated sulfur dioxide.
It can be seen that if the content of organic sulfur is to be detected, the method commonly used at present is to burn coal gas under the condition of hydrogen to generate hydrogen sulfide, and detect the hydrogen sulfide through chromatography. Or burning coal gas under oxygen, and detecting the amount of generated sulfur dioxide. But the speed of detecting sulfur element in the blast furnace gas by adopting the gas chromatography is low, and the operation is complex. For field workers, the operation difficulty is high and the efficiency is low. For enterprises with a plurality of coke ovens, the sulfur content detection in each coke oven gas cannot be included in daily detection. And the gas chromatograph is expensive, which can undoubtedly increase production and operation costs for enterprises. Therefore, development of a method for rapidly and simply detecting the sulfur content in coke oven gas is imperative.
