Thermosiphon Cooling System for a Methanation Reactor: An Experimental Assessment

Jan Van Herle, Philippe Aubin

Operating the cooling system of a methanation reactor using an open-loop two-phase thermosiphon with evaporating water as the cooling liquid is an effective way to ensure safe operation as it does not rely on a recirculating pump. The aim of the reactor de ...
