Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jet loop reactors face limitations in scalability and efficiency due to low volumetric mass transfer coefficients, heat dissipation issues, and high energy dissipation at high production capacities, particularly with a narrow height-to-diameter ratio that restricts reactor design and performance.
Innovation Solution
Interconnecting multiple jet loop reactors in parallel with common outer liquid recirculation allows for high production capacities, maintaining intensive mass transport and heat dissipation while reducing capital and operating costs by using a single pump for recirculation, and eliminating the need for internal heat exchangers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the height-to-diameter ratio of a single jet loop reactor is increased to improve heat dissipation and mass transfer, then heat exchange efficiency and mass transfer coefficients are improved, but reactor installation height increases and capital costs increase
Solution Approach 1:
The patent divides a single tall reactor into multiple shorter reactors connected in parallel. Each reactor maintains an optimized height-to-diameter ratio for effective heat dissipation and mass transfer, while the parallel configuration achieves the required production capacity without excessive installation height. The reactors share common outer liquid recirculation systems, reducing overall system complexity.
2Productivity
If multiple jet loop reactors are connected in parallel to increase production capacity, then productivity increases and heat dissipation is maintained, but device complexity and capital costs increase
Solution Approach 1:
The patent combines multiple jet loop reactors in parallel configuration while merging their outer liquid recirculation systems into a single shared system. This approach increases production capacity through parallel reaction volumes while reducing device complexity by eliminating redundant pumps and external recirculation loops. The shared recirculation system reduces capital costs and simplifies operation compared to individually recirculating each reactor.
3Temperature
If internal heat exchangers are installed in jet loop reactors to improve heat exchange, then heat dissipation efficiency is improved, but device complexity and design outlay increase
Solution Approach 1:
The patent extracts the heat exchange function from the internal reactor structure and relocates it to the outer liquid recirculation system. By using the external recirculation loops as heat exchange pathways, the system achieves effective heat dissipation without installing complex internal heat exchanger equipment within the reactors. This approach simplifies reactor design while maintaining thermal management efficiency.
