  • Gas Separation By Absorption (AREA)

Abstract

En una unidad de hidrocraqueo, se alimentan los gases vaporizados (flash gases) provenientes del separador de alta presion al fondo de una zona de absorcion en la cual los gases entrantes son puestos en contacto a contracorriente con un solvente pobre. El solvente pobre elimina por absorcion el contenido de metano, etano, propano, butanos y pentanos (c1+) del contenido de hidrogeno. La corriente de gas que sale de la parte superior de la zona de absorcion contiene tipicamente hidrogeno con una pureza de 90 a 98 mol%, o aun mayor, hidrogeno que es alimentado a la corriente de gas reciclado para proveer hidrogeno con una pureza en la gama de 96 a 99 mol%, con lo cual se provee un aumento de la eficiencia total de la unidad hidroprocesadora.In a hydrocracking unit, the vaporized gases (flash gases) from the high pressure separator are fed to the bottom of an absorption zone in which the incoming gases are brought into countercurrent contact with a poor solvent. The poor solvent removes the content of methane, ethane, propane, butanes and pentanes (c1 +) from the hydrogen content by absorption. The gas stream leaving the upper part of the absorption zone typically contains hydrogen with a purity of 90 to 98 mol%, or even greater, hydrogen that is fed to the recycled gas stream to provide hydrogen with a purity in the range from 96 to 99 mol%, which provides an increase in the total efficiency of the hydroprocessor unit.
