Comprehensive Prevention And Control Technology For Petroleum Sulfonate Production Process Pollution

In this paper, the petroleum sulfonate production process pollution were analyzed, and studied the sulfonated exhaust gas and solid waste pollution prevention and control technology, sodium hydroxide concentration, gas flow is studied through experiments and the influence of SO2 concentration on desulfurization efficiency, and the alkali absorption method of removal of sulfur dioxide in the study of engineering application. The following conclusions:(1) The main petroleum sulfonate production craft waste gas pollution from gas liquid mixture gas liquid separation process, the main pollutant for SO2, SO3, and organic acid droplets, the SO2 emissions, the biggest pollution to the environment is the most serious; Solid waste pollution mainly comes from air drying system to produce waste silica gel, occurring in the process of catalytic oxidation of sulfur dioxide waste V2O5.(2) Sodium hydroxide on the removal rate of sulfur dioxide has a great influence, when sodium hydroxide concentration is 10%, sulfur dioxide removal rate as high as 86.4%; When sodium hydroxide concentration is 30%, sulfur dioxide removal rate increased to 98%. SO2 removal rate increased with the increase of flue gas flow presents the first rise again to reduce the tendency, the flue gas flow is 200L/min, the SO2 removal rate as high as 97.1%.12 min SO2 concentration was 1%, desulfurization desulfurization rate was 95.1%, the concentration increases to 4%, the desulfurization rate decreased obviously, dropped to 78.1%. Sodium hydroxide method to remove sulfur dioxide best experiment condition is:the sodium hydroxide concentration is 30%, the flue gas flow is 200L/min, sulfur dioxide concentration was 1%, the desulfurization efficiency of 98%.(3) V2O5 and silica gel storage, transportation, receiving, etc. Shall be carried out in accordance with the measures for the management of hazardous waste management, Comprehensive utilization of waste V2O5 particles return to suppliers to reproduce. Desiccant silica gel, entrust a qualified units waste for disposal.(4) The research results show that SO2 removal rate increased with the increase of liquid gas ratio increase, when the liquid gas ratio increases to 4L/m3, the removal rate of sulfur dioxide leveling off; Absorption tower air velocity increases, the desulfurization efficiency is lower; The desulfurization rate and decreased with the increase of inlet concentration of sulfur dioxide. Studies have found that the best industrial application conditions for alkali absorption desulfurization method: 3-4L/m3, liquid absorption tower air velocity control in 0.5-1.5m/s best, best inlet SO2 concentration to 1200 ppm Of sulfonated exhaust inlet, outlet monitoring, results show that the inlet concentration of sulfur dioxide in 1200-1400mg/m3, the alkali absorption of SO2 removal efficiency as high as 96.2%.
