A novel design for the nozzle of a laminar jet absorber has been produced and used to obtain high-quality absorption-kinetics data devoid of interfacial resistance and interfacial turbulence. The nozzle design consists of a circular hole in a 0.07 ± 0.005 mm thick stainless steel sheet having an inside diameter of between 0.50 and 0.65 mm. The hydrodynamics of the various jets produced from this nozzle were checked by studying the physical absorption of carbon dioxide into water and nitrous oxide into monoethanolamine. Wetting of the orifice face, oscillations in the jet, and interfacial resistance were completely absent. In addition, the new nozzle design was tested by comparing the measured kinetics data with published data for carbon dioxide reactive absorption in monoethanolamine solutions. The measured kinetic data were in excellent agreement with literature data obtained over a period of four decades. This shows that the nozzle design produces high-quality absorption data, and that the kinetic data obtained were accurate and not subject to any interfacial turbulence.
