Zusammenfassung: | PROCESSES AND HYDROCARBON PROCESSING APPARATUSES (12) FOR PREPARING MONO-OLEFINS ARE PROVIDED. AN EXEMPLARY PROCESS INCLUDES SEPARATING A HYDROCARBON FEED (14) INTO A FIRST FRACTION (16A, 16B) OF CARBON-CONTAINING COMPOUNDS HAVING LESS THAN OR EQUAL TO 5 CARBON ATOMS AND A SECOND FRACTION (18) OF COMPOUNDS THAT HAVE A LOWER VAPOR PRESSURE THAN THOSE IN THE FIRST FRACTION. DIENES AND/OR ACETYLENES FROM THE FIRST FRACTION ARE SELECTIVELY HYDROGENATED INTO CORRESPONDING MONO-OLEFINS. PARAFFINS FROM THE FIRST FRACTION ARE CONVERTED INTO CORRESPONDING MONO-OLEFINS. THE CONVERTED MONO-OLEFINS ARE CONTACT COOLED WITH AN IMPURITY-CONTAINING LIQUID HYDROCARBON STREAM (46), WITH THE IMPURITIES IN THE IMPURITY-CONTAINING LIQUID HYDROCARBON STREAM HAVING A LOWER VAPOR PRESSURE THAN COMPOUNDS IN THE FIRST FRACTION. THE DIENES AND/OR ACETYLENES FROM THE FIRST FRACTION ARE SELECTIVELY HYDROGENATED PRIOR TO CONVERTING THE PARAFFINS FROM THE FIRST FRACTION INTO MONO-OLEFINS AND AFTER SEPARATING THE FIRST FRACTION FROM THE HYDROCARBON FEED.
