Mass transfer during bubbling in single and multi-orifice absorbers

Abstract An experimental study is described of the process of mass transfer during continuous bubbling in single and multi-orifice plates. The regions of bubble formation and bubble rise are considered separately and the values of the corresponding interfacial areas, gas side and liquid side transfer coefficients are determined. For the multi-orifice absorbers the values of these parameters per orifice are compared with the corresponding values for single orifice absorbers. This provides a reasonable test of the idea that a multi-orifice absorber may be regarded as a set of single orifice absorbers operating in parallel.
