Abstract
A method of separating a feed stream in a distillation tower. Vapor is permitted to rise upwardly from a distillation section of the distillation tower. A feed stream is introduced into a controlled freeze zone section of the distillation tower, the controlled freeze zone section being situated above the distillation section. The feed stream is released above a level of a liquid retained by a melt tray assembly in the controlled freeze zone section. Vapor from the distillation section is directed into the liquid retained by the melt tray assembly. A solid is formed from the feed stream in the controlled freeze zone section.
Claims8
A distillation tower for separating a feed stream, the distillation tower comprising:
- a distillation section permitting vapor to rise upwardly from said distillation section;
- a controlled freeze zone section situated above the distillation section, the controlled freeze zone constructed and arranged to form a solid from a feed stream, the controlled freeze zone section including
- a spray assembly in the controlled freeze zone upper section, and
- a melt tray assembly in the controlled freeze zone lower section;
- wherein the melt tray assembly includes
- a feed stream manifold that directs the feed stream into the distillation tower,
- at least one vapor stream riser that directs the vapor from the distillation section into liquid retained by the melt tray assembly, wherein the at least one vapor stream riser passes through the feed stream manifold without mixing the feed stream with the vapor stream from the distillation section, and
- at least one feed stream riser, each feed stream riser having a lower end operationally connected to the feed stream manifold and an upper end positioned above a level of the liquid retained by the melt tray assembly, wherein the feed stream is released above the level of the liquid retained by the melt tray assembly.
