<p>Proteins are prepared in reactor A by the reaction of a hydrocarbon utilizing microbe on a low molecular weight hydrocarbon, such as methane, in an aqueous medium in the presence of oxygen and a fixable nitrogen compound. Protein is recovered in Unit B, and a gaseous dioxide is passed from the reactor A to the separator C where it is separated by pressure swing adsorption in one or two stages, so as to form a carbon dioxide stream and to recycle unreacted hydrocarbon and oxygen to the reactor A. Sufficient hydrocarbon is introduced into the system to prevent the formation of a flammable mixture therein. Part or all of the hydrocarbon can be introduced into the system downstream of the reactor A, where the propensity for forming a flammable gas mixture is greatest. <IMAGE></p> |
