Total Claims: 2
Claim 1
Independent Claim
83 words
A METHOD FOR CONTINUOUSLY HEAT-TREATING LIQUIDS SENSITIVE TO HEAT, WHICH COMPRISES VAPORIZING PART OF THE LIQUID AT A TEMPERATURE BELOW THE TEMPERATURE DETRIMENTAL TO THE LIQUID, CONDENSING THE RESULTING VAPOR BY COOLING, HEATING THE RESULTING CONDENSATE UNDER ELEVATED PRESSURE SUFFICIENTLY TO TRANSFER SAID CONDENSATE INTO VAPOR, FEEDING SAID LAST VAPOR TO LIQUID WHICH IS TO BE HEAT-TREATED THEREBY HEATING SAID LIQUID, AND RAPIDLY BOILING OFF VAPOR FROM SAID HEATED LIQUID SUFFICIENTLY TO COOL SAID LAST LIQUID TO A TEMPERATURE BELOW SAID DETRIMENTAL TEMPERATURE.
