Abstract

Se proporcionan procesos y aparatos de procesado de hidrocarburos para la preparación de mono-olefinas. Un proceso ejemplar incluye separar una corriente de alimentación de hidrocarburos para dar lugar a una fracción de compuestos que contienen carbono que tiene una cantidad menor o igual a 5 átomos de carbono y una segunda fracción de compuestos que tienen una presión de vapor menor que la de la primera fracción. Se hidrogenan selectivamente dienos y/o acetilenos a partir de la primera fracción para dar lugar a las correspondientes mono-olefinas. Las parafinas procedentes de la primera fracción se convierten en las correspondientes mono-olefinas. Las mono-olefinas convertidas se enfrían por contacto con una corriente líquida de hidrocarburos que contiene impurezas, presentando las impurezas de la corriente líquida de hidrocarburos que contiene impurezas una presión de vapor menor que los compuestos de la primera fracción. Los dienos y/o acetilenos de la primera fracción se hidrogenan selectivamente antes de la conversión de las parafinas procedentes de la primera fracción en mono-olefinas y después de separar la primera fracción de la corriente de alimentación de hidrocarburos.Processes and apparatus for processing hydrocarbons for the preparation of mono-olefins are provided. An exemplary process includes separating a hydrocarbon feed stream to give rise to a fraction of carbon-containing compounds having an amount less than or equal to 5 carbon atoms and a second fraction of compounds having a vapor pressure less than that of The first fraction. Dienes and / or acetylenes are selectively hydrogenated from the first fraction to give rise to the corresponding mono-olefins. The paraffins from the first fraction become the corresponding mono-olefins. The converted mono-olefins are cooled by contact with a liquid hydrocarbon stream containing impurities, the impurities of the liquid hydrocarbon stream containing impurities having a vapor pressure lower than the compounds of the first fraction. The dienes and / or acetylenes of the first fraction are selectively hydrogenated before the conversion of the paraffins from the first fraction into mono-olefins and after separating the first fraction of the hydrocarbon feed stream.
