Dehydrogenation process

Claim 1

AN IMPROVED PROCESS FOR THE DEHYDROGENATION OF ORGANIC COMPOUNDS WHICH COMPRISES: HEATING IN A DEHYDROGENATION ZONE AT A TEMPERATURE OF AT LEAST 400* C. A MIXTURE OF AN ORGANIC COMPOUND TO BE DEHYDROGENATED, OXYGEN, AND AT LEAST ABOUT 0.001 MOL OF AMMONIUM HALIDE PER MOL OF SAID ORGANIC COMPOUND TO FORM A GASEOUS DEHYDROGENATION ZONE EFFLUENT AT A TEMPERATURE OF GREATER THAN 400*C., SAID EFFLUENT COMPRISIN DEHYDROGENATED ORGANIC COMPOUND, STEAM AND AMMONIUM HALIDE; QUENCHING THE SAID EFFLUENT WITH AN AQUEOUS QUENCH IN A FIRST SEPARATING STEP SEPARATING FROM THE QUENCHED EFFLUENT A NON-GASEOUS PHASE COMPRISING AT LEAST ABOUT 25 MOL PERCENT OF THE AMMONIUM HALIDE AND A GASEOUS PHASE COMPRISING STEAM, THE UNSATURATED ORGANIC COMPOUND AND THE REMAINDER OF THE AMMONIUM HALIDE; IN A SECOND STEP CONDENSING FROM ABOUT 20 TO 75 MOL PER CENT OF THE STEAM FROM THE SAID GASEOUS PHASE TO FORM A CONDENSATE CONTAINING CONDENSED STEAM AND AMMOUNIUM HALIDE AND A VAPOR PHASE COMPRISING THE UNSATURATED ORGANIC COMPOUND AND THE UNCONDENSED STEAM, THE RATIO OF THE MOLS OF AMMONIUM HALIDE CONTAINED IN THE SAID CONDENSATE TO THE MOLS AMMONIUM HALIDE REMAINING IN THE SAID VAPOR PHASE BEING AT LEAST 10 PERCENT GREATER THAN THE RATIO OF THE MOLS OF STEAM CONDENSED IN SAID SECOND STEP TO THE MOLS OF STEAM REMAINING IN SAID VAPOR PHASE, AT LEAST 80 MOL PERCENT OF THE AMMONIUM HALDIE ORIGINALLY PRESENT IN THE SAID DEHYDROGENATION ZONE EFFLUENT HAVING BEEN REMOVED FROM THE GASEOUS PHASE IN THE FIRST AND SECOND SEPARATION STEPS AND SEPARATING THE UNSATURATED ORGANIC COMPOUND PRODUCT FROM THE SAID VAPORPHASE OF THE SECOND STEP.
