Heat exchange apparatus

Abstract

Abstract 1. AN APPARATUS FOR THE CONVERSION OF A HYDROCARBON WHICH COMPRISES: (A) A REACTION CHAMBER HAVING MEANS FOR THE CONVERTING OF SAID HYDROCARBON, (B) HYDROCARBON INLET MEANS CONNECTED TO SAID REACTION CHAMBER FOR INTRODUCING SAID HYDROCARBON THEREIN, (C) VAPOR INLET MEANS CONNECTED TO SAID REACTION CHAMBER FOR INTRODUCING VAPOR WATER AS A HEAT EXCHANGE MEDIUM INTO SAID REACTION CHAMBER TO ADMIX WITH SAID HYDROCARBON AND TO MAINTAIN THE TEMPERATURE OF THE ADMIXTURE AT REACTION CONDITIONS, (D) A HEAT EXCHANGE CHAMBER (WITHIN SAID REACTION CHAMBER), (E) A FLOATING TUBE BUNDLE CONTAINED WITHIN SAID HEAT EXCHANGE CHAMBER COMPRISING A SUBSTANTIALLY HORIZONTAL FIXED TUBE SHEET DISPOSED COMPLETELY ACROSS AND ATTACHED TO THE INTERIOR OF SAID HEAT EXCHANGE CHAMBER, A SUBSTANTIALLY HORIZONTAL FLOATING TUBE SHEET SPACED FROM THE FIRST TUBE SHEET AND DISPOSED SUBSTANTIALLY ACROSS THE HEAT EXCHANGE CHAMBER, BUT UNATTACHED THERETO AND A PLUARLITY OF SPACED APART SUBSTANTIALLY VERTICAL HEAT EXCHANGE TUBES CONNECTED BETWEEN SAID TUBE SHEETS WITH THE INTERIOR OF SAID TUBES COMMUNICATING THROUGH SAID TUBE SHEETS, THE INTERIORS OF SAID TUBES ESTABLISHING MIXTURE PASSAGEWAYS AND THE SPACE AROUND SAID TUBES ESTABLISHING HEAT EXCHANGE PASSAGEWAYS, (F) MEANS CONNECTED TO THE DOWNSTREAM END OF SAID REACTION CHAMBER AND TO THE MIXTURE PASSAGEWAYS OF SAID TUBE BUNDLE FOR INTRODUCING THE TOTAL EFFLUENT FROM THE DOWNSTREAM END OF SAID REACTION CHAMBER INTO SAID MIXTURE PASSAGEWAYS, (G) CONDENSER MEANS DISPOSED WITHIN SAID HEAT EXCHANGE CHAMBER BELOW SAID FLOATING TUBE BUNDLE AND DOWNSTREAM OF SAID MIXTURE PASSAGEWAYS FOR CONDENSING AT LEAST A PORTION OF THE VAPOR WATER IN SAID TOTAL EFFLUENT TO A LIQUID WATER, (H) SETTLING MEANS WITHIN SAID BEAT EXCHANGE CHAMBER BELOW SAID FLOATING TUBE BUNDLE AND DOWNSTREAM OF SAID CONDENSER MEANS FOR SETTLING AND SEPARATING THE LIQUID WATER FROM THE TOTAL EFFLUENT, (I) MEANS FOR CARRYING LIQUID WATER THROUGH THE HEAT EXCHANGE PASSAGEWAYS OF SAID TUBE BUNDLE, WHEREBY SAID LIQUID WATER IS IN INDIRECT HEAT EXCHANGE RELATIONSHIP WITH THE TOTAL EFFLUENT AND WHEREBY THE TEMPERATURE OF SAID WATER IS RAISED AND THE TEMPERATURE OF THE TOTAL EFFLUENT IS LOWERED, (J) HEATER MEANS COMMUNICATING WITH THE DOWNSTREAM END OF SAID HEAT EXCHANGE PASSAGEWAYS FOR HEATING THE WATER THEREFROM TO THE EXTENT WHERE IT MAY BE UTILIZED AS A VAPOR HEAT EXCHANGE MEDIUM FOR SAID REACTION CHAMBER, (K) MEANS FOR TRANSFERRING THE VAPOR WATER FROM SAID HEATER MEANS TO THE VAPOR INLET MEANS OF SAID REACTION CHAMBER, AND, (L) OUTLET MEANS DISPOSED DOWNSTREAM OF SAID CONDENSER MEANS FOR REMOVING SEPARATED FRACTIONS OF SAID TOTAL EFFLUENT.
