Capture of Particles of Benzene in the Coke Oven Gas by Packed-Type Scrubbers


Abstract. In this paper, we consider the peculiarities of capture of the particles of benzene in coke oven gas by a packed-type scrubber. Experimental and theoretical data on the dependence of the number of particles on temperature and pressure were analysed and processed. The regression equation is obtained, which allows calculating the efficiency of capturing of benzene particles as a function of temperature and pressure. Based on the statistical analysis of the equation of regression of experimental data, the factor that most influences the efficiency of capturing of benzene particles is revealed. This factor is the temperature. The point elasticity coefficient for this factor exceeds three, and for other factors, this coefficient is much less than one. It is shown that in order to intensify the capturing it is necessary to minimize the process temperature as much as possible. The graph is built by the regression equation.


Key words: scrubber, coke oven gas, benzene, emissions, cap, coke industry
