Abstract:

According to the analysis of benzol scrubbing process,the main factors influencing the scrubbing efficiency are found out.For the problems of high benzol content after the scrubber,low benzol content in rich oil and low spray density,an additional circulating stage of semi-rich oil is provided in the benzol scrubber.The problem of high gas temperature at downstream of the scrubber is solved by adjusting the chilled water quantity and establishing regular cleaning rule for the cooler.
