Vapor-Liquid Interface Condensation via Diffusion Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional condensing systems are energy and cost intensive due to the need for expensive chilling equipment and limited scalability, as they rely on chilling a solid surface area that restricts the condensation rate of volatilized substances.
Innovation Solution
A system that uses a cooled reservoir of liquid to condense volatilized substances by passing vapor bubbles through it, increasing the cooled surface area and reducing the need for low-temperature cooling, thereby eliminating the requirement for power-hungry chillers and allowing for scalable expansion with larger heat exchangers and pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a chilled substance is circulated through a jacketed vessel to condense vapor, then the vapor condensation function is achieved, but the available chilled surface area limits the condensation rate
Solution Approach 1:
The patent uses a liquid reservoir instead of a solid chilled surface, allowing vapor to bubble through the liquid and condense. This hydraulic approach provides vastly increased surface area for heat transfer compared to traditional jacketed vessels, directly resolving the contradiction between limited surface area and required condensation rate.
Solution Approach 2:
The invention transitions from a two-dimensional solid surface (jacketed vessel) to a three-dimensional liquid volume (reservoir). By allowing vapor to penetrate into the liquid phase rather than just contacting a surface, the effective heat transfer area increases dramatically, solving the surface area limitation.
2Temperature
If refrigerant compressor systems or liquid nitrogen/CO2 are used to chill surfaces, then condensation capability is improved, but the process becomes cost and energy intensive
Solution Approach 1:
The liquid reservoir serves a dual function: it provides the cooling medium and simultaneously acts as the condensation surface. The liquid absorbs heat from condensing vapor and is naturally circulated back through the heat exchanger, creating a self-sustaining cycle that eliminates the need for external refrigerant compressors or expensive chilling agents.
Solution Approach 2:
The invention changes the temperature parameter of the cooling medium from extremely low temperatures (liquid nitrogen/CO2) or refrigerant temperatures to near-ambient temperatures. The liquid reservoir operates effectively at temperatures close to room temperature, dramatically reducing energy consumption while maintaining adequate condensation performance.
3Productivity
If conventional chillers are used to increase condensation rate, then more vapor can be condensed, but scalability is limited by high energy costs and water capacity requirements
Solution Approach 1:
The system is divided into modular components: the liquid reservoir, heat exchanger, and circulation pump. This segmentation allows the system to be scaled by adding parallel reservoirs or increasing the size of individual components without requiring complete system replacement, enabling flexible adaptation to different production requirements.
4Productivity
If a larger heat exchanger or radiator is used in the liquid reservoir system, then the condensation rate can be increased, but the system complexity increases
Solution Approach 1:
The liquid reservoir performs multiple functions simultaneously: it serves as the cooling medium storage, the condensation chamber, and the heat transfer surface. This multi-functionality eliminates the need for separate chilled surfaces, refrigerant systems, and circulation mechanisms, keeping the system simple despite increased condensation capacity.

This approach enhances the efficiency of the condensation process, reduces energy costs, and eliminates the need for expensive chilling equipment, while maintaining comparable condensation rates and allowing for scalable solutions that do not require significant water resources.
Implementation Method 1
The vapor condenses rapidly as soon as it comes into contact with the cooled liquid, due to the large cooled surface area available for condensation
Implementation Method 2
the circulation pump pumps the cooling liquid from the condenser vessel through the heat exchanger and back to the condenser vessel
Implementation Method 3
a heat exchanger connected in fluid communication with the circulation pump and the condenser vessel

AI summary
A volatilized substance is condensed using a vapor-liquid interface. The volatilized substance is diffused into a condenser vessel containing a cooling liquid via a diffusion device. When the volatilized substance comes into contact with the cooling liquid it is condensed. The large vapor-liquid surface area created by the diffusion device enhances the rate of condensation. The cooling liquid is circulated through a heat exchanger to remove heat introduced by the condensing vapor. The temperatures of the cooling liquid leaving and entering the condenser vessel are monitored.
