With the coming of national and local regulations, the supervision is also upgraded year by year, and more efficient development and application of waste gas treatment technology are urgently needed.
Because the process of the petroleum refining or chemical industry is complex, the source items are numerous, the components of the generated waste gas are complex, and the absorption or absorption means used singly is difficult to meet the current tail gas emission requirement. At present, the incineration technology is still the most efficient means for treating the waste gas so as to meet the increasingly severe requirements for tail gas emission. However, during the actual production operation, the waste gas is not generated at a constant flow rate, for example, when the raw material is added, the gas amount is increased rapidly in a short time; the waste gas generated by the large breath in the feeding process of the storage tank is larger than that generated by the small breath, and the storage tank is in the small breath for most of time; most importantly, when an enterprise performs opening and closing, overhaul and maintenance, the waste gas generation amount can be obviously fluctuated greatly due to intermittent purging on pipelines with different pipe diameters, reaction kettles with different specifications and the like.
