Abstract

Se describe un proceso para recuperar etano, etileno, propano, propileno y componentes de hidrocarburo más pesados de un flujo de gas de hidrocarburo. El flujo se divide en un primer y segundo flujo, y el segundo flujo se expande a la presión de la torre fraccionadora y se suministra a la columna en una posición de alimentación y se suministra a la columna en una posición de alimentación en la parte media de la columna. Un flujo de reciclaje se extrae de vapor saliente de la parte alta de la torre después de haberse calentado y comprimido, y se combina con el primer flujo. El flujo combinado se enfria para condensar sustancialmente todo este flujo y, luego, se expande a la presión de la torre fraccionadora y se suministra a esta última en una posición de alimentación en la parte superior de la columna. La presión del flujo de reciclaje comprimido y las cantidades y temperaturas de las alimentaciones de la columna son efectivas para hacer que la temperatura del vapor saliente de laparte alta de la columna se mantenga a un grado tal que permita recuperar la principal porción de los componentes deseados.A process for recovering ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is described. The flow is divided into a first and second flow, and the second flow expands at the pressure of the fractionating tower and is supplied to the column in a feeding position and is supplied to the column in a feeding position in the middle part of the column. A recycle stream is drawn from outgoing steam from the top of the tower after it has been heated and compressed, and combined with the first stream. The combined flow is cooled to condense substantially all of this flow, and then expands under pressure from the fractionating tower and is supplied to the fractionating tower at a feed position at the top of the column. The pressure of the compressed recycle stream and the amounts and temperatures of the column feeds are effective in keeping the temperature of the outgoing steam from the top of the column maintained to such a degree as to allow the main portion of the desired components to be recovered .
