METHOD FOR HEAT DEMERCURIZATION OF MERCURY CONTAINING MATERIALS AND APPARATUS FOR PERFOMING THE SAME Russian patent published in 2001 - IPC

FIELD: procession of mercury containing materials, particularly evaporation of mercury out of zinc cementate. SUBSTANCE: method comprises steps of distilling mercury in circulating stream of inert gas in closed contour. Apparatus for performing the method includes reservoir with processed material, heater, entrainment unit and pump; it is provided in addition with jet pump arranged in front of entrainment unit having separator with cyclone, heat exchanger joined with jet pump and separator through pump. All units of apparatus form two closed contours, namely: gas stream contour including jet pump, separator, heater and reservoir with processed material and liquid phase contour including separator, pump, heat exchanger, jet pump. EFFECT: enhanced ecological properties of system due to improved design of apparatus. 2 cl, 1 dwg
