Claim 1
Independent Claim

IN A PROCESS WHEREIN HIGH TEMPERATURE ARE PRODUCED BY INTRODUCING REACTANTS INTO A REACTION ZONE MAINTAINED AT ELEVATED PLRESSURE AND EFFECTING REACTION SAID ZONE, AND PRODFUCT GASES ARE CONTACTED IN A COOLING ZONE MAINTAINED AT SUBSTANTIALLY SAID ELEVATED PRESSURE WITH A VOLATDILE COOLING LIQUID HAVING A BOILING POINT BELOW THE TEMPERATURE AT WHICH SAID GASES ARE PRODUCED, THE METHOD OF SHUTTING DOWN THE GAS GENERATION SYSTEM WHICH COMPRISES DISCONTINUING THE INTRODUCTION OF REACTANTS TO SAID REACTION ZONE WITHOUT SUBSTANTIAL REDUCTION IN PRESSURE THEREIN, CONTINUOUSLY SUPPLYING SAID COOLING LIQUID TO SAID COOLING ZONE ASSOCIATED WITH SAID REACTION ZONE AT A TEMPERATURE BELOW TH TEMPERATURE CORRESPONDING TO THE BOILING POINT OF SAID LIQUID AT THE EXSISTING PRESSURE, AND REDUCING THE PRESSURE IN SAID GAS GENERATDION SYSTEM BY WITHDRAWAL OF GAS THEREFROM AT A RATE SUCH THAT THE PRESSURE IN SAID REACTION ZONE IS MAINTAINED IN EXCESS OF THE VAPOR PRESSURE OF THE COOLING LIQUID IN SAID COOLING ZONE.
