Abstract
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.
Claims20
A method of improving flow distribution of one or more streams in a process vessel comprising:
- passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials;
- and
- passing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone has a depth of four feet or less and contains treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone.
A method of improving flow distribution of one or more streams in a process vessel comprising:
- passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials;
- and
- passing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone contains a plurality of treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone,
- and wherein the redistribution treating zone is adjacent to the upstream processing zone and a permeable membrane is disposed between the treating elements in the redistribution treating zone and the processing materials in the upstream processing zone such that the processing materials from the upstream processing zone cannot migrate into the redistribution treating zone but the stream flow may pass through the membrane.
A method of improving flow distribution of one or more streams in a process vessel comprising:
- passing the one or more streams through an upstream processing zone and a downstream processing zone within the process vessel, the upstream processing zone and downstream processing zone each containing one or more beds of processing materials;
- and
- passing the one or more streams through a redistribution treating zone located between the upstream processing zone and downstream processing zone, wherein the redistribution treating zone contains packed treating elements and wherein the redistribution treating zone mitigates stream channeling of the streams exiting the upstream processing zone and affects lateral redistribution of the flow of the one or more streams within the downstream processing zone,
- and wherein the redistribution treating zone is directly adjacent to the upstream processing zone such that certain of the processing materials from the upstream processing zone are capable of migrating into the redistribution treating zone to create a combo-zone having both processing zone functionality and treating zone functionality, and wherein the redistribution treating zone contains a plurality of treating elements.

- and wherein the processing materials occupy at least 20% of the volume of that portion of the layer of treating elements contained in the redistribution treating zone into which the processing materials have migrated.
