Abstract
Processes and hydrocarbon processing apparatuses for preparing mono-olefins are provided. An exemplary process includes separating a hydrocarbon feed into a first fraction of carbon-containing compounds having less than or equal to 5 carbon atoms and a second fraction 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, 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.
