Claim 1
Independent Claim
147 words
A METHOD FOR AVOIDING UNDESIRED REACTIONS OF A CONTINUOUS BODY OF A FIRST LIQUID WHILE INTRODUCING SAID FIRST LIQUID AS A FEED STREAM INTO A TURBULENT BODY OF A SECOND LIQUID, SAID LIQUIDS CAUSING AN UNDESIRABLE REACTION WHEN THE SECOND LIQUID ENTERS THE FIRST LIQUID FEED STREAM, SAID METHOD COMPRISING FEEDING A STREAM OF GAS INTO THE CONTINOUS BODY OF SAID FIRST FEED STREAM AND FEEDING SAID STREAM OF GAS TOGETHER WITH SAID FIRST LIQUID TOWARD THE TURBULENT BODY OF SAID SECOND LIQUID, INTERRUPTING THE FLOW OF SAID FIRST LIQUID WHILE CONTINUING THE FLOW OF GAS AT SUFFICIENT VELOCITY TO PREVENT ENTRY OF SAID SECOND LIQUID INTO FIRST LIQUID FEED STREAM, SAID STREAM OF GAS BEING FED IN STREAMLINE FASHION AND AT A SLOWER RATE OF FEED THAN THE FEED RATE OF SAID FIRST LIQUID TO THEREBY AVOID INTRODUCING ANY TURBULENCE IN SAID FIRST LIQUID FEED STREAM.
Claim 2
Independent Claim
147 words
A METHOD FOR AVOIDING UNDESIRED REACTIONS OF A CONTINUOUS BODY OF A FIRST LIQUID WHILE INTRODUCING SAID FIRST LIQUID AS A FEED STREAM INTO A TURBULENT BODY OF A SECOND LIQUID, SAID LIQUIDS CAUSING AN UNDESIRABLE REACTION WHEN THE SECOND LIQUID ENTERS THE FIRST LIQUID FEED STREAM, SAID METHOD COMPRISING FEEDING A STREAM OF GAS INTO THE CONTINOUS BODY OF SAID FIRST FEED STREAM AND FEEDING SAID STREAM OF GAS TOGETHER WITH SAID FIRST LIQUID TOWARD THE TURBULENT BODY OF SAID SECOND LIQUID, INTERRUPTING THE FLOW OF SAID FIRST LIQUID WHILE CONTINUING THE FLOW OF GAS AT SUFFICIENT VELOCITY TO PREVENT ENTRY OF SAID SECOND LIQUID INTO FIRST LIQUID FEED STREAM, SAID STREAM OF GAS BEING FED IN STREAMLINE FASHION AND AT A SLOWER RATE OF FEED THAN THE FEED RATE OF SAID FIRST LIQUID TO THEREBY AVOID INTRODUCING ANY TURBULENCE IN SAID FIRST LIQUID FEED STREAM.
Claim 3
Dependent Claim
106 words
IN A PROCESS FOR REACTING LIQUID CYCLOHEXANONE OXIME WITH A MIXTURE OF SULFURIC ACID AND CAPROLACTAM, WHEREIN LIQUID CYCLOHEXANONE OXIME IS FED INTO A TURBULENT MIXTURE OF SULFURIC ACID AND CAPROLACTAM, THE METHOD OF AVOIDING UNDESIRED VIOLENT REACTIONS WHILE FEEDING LIQUID CYCLOHEXANONE OXIME INTO SAID TURBULENT MIXTURE WHICH COMPRISES FLOWING LIQUID CYCLOHEXANONE OXIME IN THE FORM OF A NON-TURBULENT FEED TOWARD THE TURBULENT MIXTURE INTRODUCING A RELATIVELY SLOW STREAM OF INERT GAS INTO SAID CYCLOHEXANONE OXIME IN STREAMLINE FASHION WITHOUT INTRODUCING ANY TURBULENCE THEREIN WHEREBY SAID CYCLOHEXANONE OXIME IS INTRODUCED INTO SAID TURBULENT MIXTURE WITHOUT THE OCCURENCE OF UNDESIRABLE VIOLENT REACTIONS IN SAID CYCLOHEXANONE OXIME FEED.
Claim 4
Dependent Claim
