Coke oven gas analysis

Coking plants (coke oven gas oxygen content analyzer) TR-9200 series oven, gas furnace, hot stove gas analysis system, in order to reduce gas emissions pollution, improve combustion efficiency, recovering sensible heat, improve product quality and special purpose design and analysis system, as coke oven gas, flue gas, coke dry quenching gas, gas furnace gas, furnace gas stove isometric indecent varying degrees contain tar, dust, low-boiling organic matter, H2S and other sulfur composition or water vapor, has a high viscosity, easy to crystallize, corrosive, etc., so gas complex composition analysis system could easily lead to blockage, corrosion. For the above, we use the system more targeted design of new technology is safe and reliable, corrosion-resistant, non-blocking, sampling authentic, fast response, high precision analysis, configuration, and selection of the best, and many other features. Coke oven gas, also known as coke oven gas. It refers to several bituminous coking coal formulated as, after high temperature carbonization in coking furnace in output [wiki] coke [/ wiki] a flammable gas and tar products produced at the same time, is the coking industry products. Coke oven gas is a mixture, its yield and composition vary depending on the quality of coking coal and coking process conditions vary, generally dry ton of coal to produce coke oven gas 300 ~ 350m3 (standard state). ● coke oven gas sample state measuring range Operating pressure -10MPa ~ + 15 MPa O2 0.00 ~ 2.00% Operating Temperature 80 ~ 150 ℃ sampling locations around electrical tar precipitation composition of the sample (former gas purification) sample composition (after gas purification) CO2 1.5% ~ 3% CO2 1.5% ~ 3% N2 3% ~ 7% N2 3% ~ 7% O2 0.3% ~ 0.8% O2 0.3% ~ 0.8% CH4 23% ~ 27% CH4 23% ~ 27% CO 5% ~ 8 % CO 5% ~ 8% H2 50% ~ 60% H2 50% ~ 60% NH3 6g / m3 NH3 0.05g / m3 H2S 6g / m3 H2S 0.2g / m3 HCN 1.5g / m3 HCN 0.3g / m3 benzene 334g / m3 benzene 4g / m3 naphthalene 23g / m3 naphthalene 0.3g / m3 tar tar saturated 0.5g / m3
