Analysis of Gas Utilization Efficiency in Injection Refining Process

Abstract:

According to practical situation of Mg-based desulphurization, this paper has defined the formula of bubble effectiveness with low ratio of height to diameter, and derived the theoretical formula of the bubble utilization rate relating to gas flow rate, bubble diameter and mass transfer coefficient. When the absorption rate is treated as first order reaction, the theoretical formula is presented which includes physical conditions, equipment conditions and operating conditions. It indirectly reflects the three conditions on the effective of bubble utilization rate. The calculation formula of bubble utilization rate at different sizes and different residence time distribution is derived.
