The presented paper describes energy saving technology of biogas purification by microbubling method Description of a new design of microbubling equipment for gas-liquid solution and mathematical simulation of a process during chemisorption of carbon dioxide are presented. Experimental studies of mass transfer characteristics of microbubling equipment, based on model systems, were conducted with an aim to define a possibility of application of microbubling process for removal of carbon dioxide from biogas in order to obtain highly concetrated metane. As a result of the study optimal process parameters are defined, key factors affecting mass transfer characteristics of membrane microbubling method are also established. Efficiency of membrane microbubling equipment from the point of view of interphase mass transfer is assessed.
