Use of treating elements to facilitate flow in vessels
A method for facilitating the distribution of the flow of one or more streams within a bed vessel is provided. Disposed within the bed vessel are internal materials and structures including multiple operating zones. One type of operating zone can be a processing zone composed of one or more beds of solid processing material. Another type of operating zone can be a treating zone. Treating zones can facilitate the distribution of the one or more streams fed to processing zones. The distribution can facilitate contact between the feed streams and the processing materials contained in the processing zones.
1. A method of improving flow distribution of one or more streams in a process vessel comprising:
passing the one or more streams through more than one processing zone within the process vessel, wherein each processing zone contains processing materials; and
passing the one or more streams through a redistribution treating zone located within the processing vessel and between an upstream processing zone and a downstream processing zone, wherein the redistribution treating zone comprises at least one layer of fixed material which provides porous structures to facilitate stream flow redistribution by laterally dispersing the one or more streams to provide improved contact between the one or more streams and the downstream processing materials within the processing vessel,
wherein certain of the processing materials from the upstream processing zone mix into the redistribution treating zone to create a combo-zone having both processing zone functionality and treating zone functionality,
wherein there is no space between the upstream processing zone and the redistribution treating zone, and
wherein the redistribution zone is located adjacent to both the upstream processing zone and the downstream processing zone.
2. The method of claim 1 , wherein a bed zone is disposed upstream of the upstream processing zone.
3. The method of claim 1 , wherein the fixed material is composed of a single layer.
4. The method of claim 1 , wherein the depth of the redistribution treating zone is two feet or less.
5. The method of claim 1 , wherein the depth of the redistribution treating zone is one foot or less.
6. The method of claim 1 , wherein the depth of the redistribution treating zone is 4 foot or less.
