A compact high performance mass transfer device capable of producing very high interfacial area and turbulence is described. Interfacial areas as high as 106 m2/m3 of absorber can be obtained which is considerably higher than coventional mass transfer devices. This allows the absorber to be compact and therefore makes it suitable for use in small scale gas fields and in remote field operations where conventional gas processing technology is not economical. This paper provides the theoretical basis of mass transfer enhancement, experimental mass transfer and fluidodynamic data for this absorber. Design equations are provided and other potential applications are discussed.
