Feed section of a separation column

摘要

A feed distribution device in separation columns and a method of operation for such a device. In particular, distillation columns in which the feed stream is substantially liquid phase, or a mixture of gas and liquid upstream of the column, but where the feed vaporizes or partially vaporizes prior to or as it enters the column. More specifically, the feed distribution device contains a plurality of opening which allow the feed to vaporize prior to or as it enters the column and where the openings are maintained in critical condition during operation. Significant advantage is achieved through the implementation and use of the present feed distribution devices.

主权项

1. A contacting column section comprising a feed distribution device comprising;
a feed line inlet for introducing a feed which is at least partially liquid to the feed distribution device, a chamber between the feed line inlet and the column, said chamber having a cross-sectional area, a means for causing the flow to be in choked condition and to simultaneously at least partially vaporize before entering the interior portion of the section of the column, and wherein the chamber at least partially surrounds a portion of the outer wall of the contacting column.
