Solution Overview

Problem

Bed vessels in the process industry face challenges with inadequate stream flow distribution, leading to channeling and inefficient utilization of internals, resulting in underexposed and overexposed materials, reduced productivity, and safety risks from conventional structured engineering devices.

Innovation Solution

Implement redistribution treating zones with treating elements, such as quasi-ellipsoid shaped ceramic reticulates, that facilitate the migration and commingling of solid processing material elements with treating materials to form combo-zones, improving stream flow distribution and contact with processing materials without the need for costly and risky conventional devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional structured engineering devices are used to facilitate flow distribution, then stream flow distribution is improved, but device complexity and operational risks increase due to the need for complex containment systems

Engineering Contradiction:

Improvestream flow distributionVSAvoidcontainment systems

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the complex containment systems from the flow distribution device, extracting only the essential flow distribution function. The treating elements are designed to perform flow redistribution without requiring external containment structures, thereby simplifying the overall device complexity while maintaining operational effectiveness.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The treating elements within the bed vessel perform the flow distribution function autonomously without requiring external containment systems or complex mechanical structures. The elements self-organize to create flow pathways and redistribute streams based on their inherent physical properties, eliminating the need for additional containment infrastructure.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If conventional structured engineering devices are installed to improve flow distribution, then stream contact with processing materials is enhanced, but space consumption increases

Engineering Contradiction:

Improvestream contact with processing materialsVSAvoidspace consumption

Core Design Contradiction:

Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent merges the flow distribution function with the existing bed vessel internals by installing treating elements directly within the bed material. This integration allows the same space to serve dual purposes: processing and flow redistribution, thereby enhancing stream contact without increasing overall space consumption.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The treating elements are distributed throughout the three-dimensional bed volume rather than being concentrated in a separate structural device. This dimensional distribution allows flow redistribution to occur across multiple spatial dimensions within the existing vessel volume, improving stream contact efficiency without requiring additional macroscopic space.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If bed vessels operate for extended periods, then productivity is maintained, but channeling occurs due to inadequate flow distribution leading to underexposed and overexposed materials

Engineering Contradiction:

Improveoperational continuityVSAvoidflow distribution uniformity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The treating elements are pre-installed within the bed vessel before operation begins, creating a flow distribution network in advance. This preliminary configuration ensures uniform stream distribution from the start of operation, preventing channeling issues that would otherwise develop during extended operational periods and maintain both productivity and reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The treating elements modify the physical parameters of flow pathways within the bed, creating optimized channels that maintain uniform velocity and distribution characteristics. These parameter modifications ensure consistent flow patterns over time, preventing the development of channeling issues that would compromise reliability during long-term operation.

Inventive Principle:

Principle #35Parameter changes

AI summary

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.
