Abstract

A three-stage cross-flow Venturi jet reactor was innovatively designed in this study to conduct an experimental study on the physical simulation of the carbonization process of calcified slag. The pH changes during CO2 absorption by NaOH were measured by a pH meter. The influence law of superficial gas velocity, superficial liquid velocity, and inlet pressure on CO2 absorption rate and utilization rate were investigated. The results show that the volumetric mass transfer coefficient with the increase of superficial gas velocity first remains unchanged and then increases, decreases with the increase of superficial liquid velocity, and increases with the increase of inlet pressure, and the latter stage is greater than the previous stage. The CO2 utilization rate does not change with the increase of superficial gas velocity and inlet liquid velocity but increases with the increase of inlet pressure and remains unchanged afterwards. This result provides support for the design and industrial application of carbonization reactors.
