Abstract

Se divulga un proceso para la recuperación de etano, etileno, propano, propileno y componentes hidrocarburicos más pesados a partir de un flujo de gas hidrocarburo. En años recientes, el método recomendado para separar un flujo de gas de hidrocarburo por lo general a incluido suministrar al menos porciones del flujo de gas de una torre de fraccionamiento que tiene al menos un hervidor, y a menudo uno o más hervidores laterales, para proporcionar calor a la columna retirando y calenrtando parte de los líquidos de la torre para producir vapores separados que dividen los componentes más volátiles de los componentes deseados. El hervidor y los hervidores laterlaes (si los hubiera generalmente están integrados en el esquema de enfriamiento de flujo de alimentación para proporcionar al menos una proción de la refrigeración necesaria para condensar los componentes deseados para un posterior fraccionamiento en la columna de destilación. En el proceso que se divulga, el esquema de hervidorde la torre se ha modificado para usar uno o mas flujos de destilación de liquido de la torre desde un punto más alto en la columna del que se usa en el esquema de hervidor convencional, proporcionando un flujo (o flujos) de menor temperatura al hervidor, lo cual permite un enfriamiento más efectivo de los flujos de alimentación y de este modo mejora la eficacia con la cual se recuperan los componentes deseados. Asi mismo, los flujos de líquido de la torre que se retiran desde un punto más alto en la columna contienen mayores cantidades de componentes más volátiles, que cuando se vaporizan proporcionan una mejor separación de los componentes indeseables como dióxido de carbono, sin reducir la recuperación de los componentes deseados. El flujo de destilación calentando regresa a un punto inferior en la torre de fraccionamiento que está separado del punto de extracción al menos en una fase teórica.A process is disclosed for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream. In recent years, the recommended method of separating a stream of hydrocarbon gas has generally included supplying at least portions of the gas stream from a fractionation tower that has at least one boiler, and often one or more side boilers, to provide Heat to the column by removing and heating part of the tower liquids to produce separate vapors that divide the most volatile components from the desired components. The kettle and later kettles (if any are generally integrated into the feed flow cooling scheme to provide at least a portion of the cooling needed to condense the desired components for further fractionation in the distillation column. In the process disclosed, the tower kettle scheme has been modified to use one or more tower liquid distillation flows from a higher point in the column than is used in the conventional kettle scheme, providing a flow (or flows) of lower temperature to the kettle, which allows a more effective cooling of the feed flows and thus improves the efficiency with which the desired components are recovered.Also, the tower liquid flows that are removed from higher points in the column contain higher amounts of more volatile components, which when vaporized provide better se stop undesirable components such as carbon dioxide, without reducing the recovery of the desired components. The heating distillation flow returns to a lower point in the fractionation tower that is separated from the extraction point in at least one theoretical phase.
