Water in the crude gasoline from the absorption tower
Thread Content
What is the impact of water in crude gasoline on the absorption efficiency of the absorption tower? How to conduct theoretical analysis?
According to the emergency knowledge questions and answers for catalytic cracking units, the presence of water in crude gasoline can lead to water accumulation in the absorption stabilization unit, when the level detection systems in the distillation tower and the liquid separation tank at the exit of the compressor fail, which in turn affects the vapor pressure of the stabilized gasoline. According to theoretical analysis, high pressure and low temperature are favorable for the absorption process. Moreover, crude gasoline already contains some moisture; therefore, the main impact is on the subsequent steps, with little effect on the absorption process itself.
