Abstract: - 23 - PREPARATION OF PROPME FROM.-PROPANE ABSTIACT THE INVENTION RELATES TO A PROCESS FOR PIEPARIN,O PIOPENE FROM PROPANE, COMPRISING THE 5 STEPS: A) A FEED GAS SIREARN A COMPSING PROPANE IS PROVIDED; B) THE FEED PAS STREAM A COMPRISING PROPANE AND AN OXYGENOUS -AS STREARN ARE FED 10 INTO A DEHYDRO.-ENATION ZONE AND PROPANE IS SUBJECTED TO A NONOXIDATIVE CAIALYLIC, AUTOTHEIRRIAL DCHYDROGENATION TO PROPENE TO OBTAIN A PI ODUCI GAS STREAM B CORNPRIS- ING PROPANE, PIOPENE, METHANE. ETHANE. ETHENE, C4' HYDROCWBOJIS, CARBON NIONOX- IDE, CAIBON DIOXIDE, STEAM AND LWDRO2CN, 15 Q THE PRODUCT OAS STREAM B IS COOLED AND SICAM IS IERNOVED BY CONDENS3TION LO OB- IAIN A SICARRI-DEPLETED PRODUCT GAS STICARN C, D) CARBON DIOXIDE IS IENIOVED BY OAS SCRUBBJN2 TO OBTAIN A CARBON DIOXIDE-DEPLETED PRODUCT GAS STREAM D, 20 E) THC PRODUCT -AS STICARN D IS COOLED AND A LIQUID HYDIOCAIBON STREAM EL CORNPLISINO PROPANE, PROPENE, METHANE, ETHANE. ETHERIC AND C@' LI@,DROCARBONS IS IEMOVED BN CONDENSATION IO LEAVE A RESIDUAL GAS STREAM E2 CORNPIISIN.- METHANE, HYDJO,GEN AND CARBON MONOXIDE. 25 F) THE LIQUID HYDROCARBON STREAM EL IS FED INTO A FIRST DISTILLATION ZONE AND SEPARATED DISTILLAIIVELY INTO A STREAM 1-1 COMPIISING PROPANE. PROPENE AND THE C4' HYDIOCAR- BONS AND A STREAM 1`2 COMPRISING ETHANE AND CIHENE. 30 G) THE STICARN FJ IS FED INTO A SECOND DISIFLLANON ZONE AND SEPARATED DISTILLANVELY INTO A PIODUCT STREAM 21 CORNPIISIN2 PROPENE AND A STREAM G2 COMPIISING PROPANE AND THE C4' HYDI OCAI BONS.
