Claim 1
Independent Claim
150 words
A PROCESS FOR CONTROLLING AT A PREDETERMINED TEMPERATURE LEVEL THE TEMPERATURE OF A FLUID STREAM PASSED TO AN EXOTHERMIC CHEMICAL REACTION WHEREIN THE HEAT OF REACTION IS CONTINUOUSLY REMOVED FROM SAID ZONE, SAID LEVEL BEING AUTOMATICALLY RESET RESPONSIVE TO MEASURED TEMPERATURE CHANGES IN SAID REACTION, WHICH COMPRISES CONTINUOUSLY MIXING A COLD PORTION OF SAID FLUID WITH A HEATED PORTION OF SAID FLUID AT A PREDETERMINED RATIO TO FORM SAID STREAM, CONTINUOUSLY MEASURING THE TEMPERATURE OF SAID STREAM AND REGULATING THE AMOUNT OF HEATED AND COLD FLUIDS MIXED RESPONSIVE TO CHANGES IN THE MEASURED TEMPERATURE SO AS TO MAINTAIN SAID STREAM AT SAID PREDETERMINED TEMPERATURE LEVEL, AND AUTOMATICALLY ADJUSTING THE TEMPERATURE OF THE HEATED STREAM RESPONSIVE TO A NEW RATIO OF SAID COLD AND HEATED PORTIONS BEING MIXED SO AS TO READJUST THE AMOUNT OF HEATED AND COLD FLUIDS MIXED TO THE ORIGINAL RATIO AND THEREBY MAINTAIN SAID PREDETERMINED DESIRED TEMPERATURE.
