Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If batch or semi-batch separation methods are used in laboratory-scale equipment, then hydrate formation can be achieved, but continuous production of purified gas cannot be realized and water solution cannot be recycled
Solution Approach 1:
The patent implements continuous operation by designing a single reactor system where gas-liquid slurry flows continuously through the reaction vessel. The system maintains continuous hydrate formation and separation without requiring multiple batch reactors, achieving uninterrupted production of purified gas while enabling water solution recycling through the continuous flow configuration.
Solution Approach 2:
The reactor is divided into multiple functional zones including a gas-liquid mixing section, a hydrate formation section, and a separation section. This segmentation allows different processes to occur simultaneously in different parts of the same continuous system, enabling continuous production without requiring multiple separate reactors.
2Quantity of substance
If conventional gas-liquid mixing is used, then hydrate formation occurs, but gas-liquid mass transfer efficiency is insufficient leading to residual target gas in the gas phase
Solution Approach 1:
The patent introduces a vibration device that generates radial vibrations in the reaction vessel, creating strong turbulence and enhancing gas-liquid mass transfer. This mechanical vibration increases the contact between gas and liquid phases, improving hydrate formation efficiency and ensuring complete capture of target gas without residual gas remaining in the gas phase.
Solution Approach 2:
The system uses a gas-liquid jet mixer that utilizes high-velocity gas and liquid jets to create intense mixing and mass transfer. The pneumatic-hydraulic interaction generates turbulence and enhances the formation of gas hydrates, significantly improving the quantity of target gas captured and the efficiency of hydrate formation.
3Manufacturing precision
If separation conditions are made more rigorous to capture more target gas, then gas separation efficiency improves, but the process becomes more complex and less suitable for industrial application
Solution Approach 1:
The patent replaces complex separation conditions with a mechanical vibration-based approach. Instead of requiring rigorous control of temperature, pressure, and composition parameters, the system uses radial vibrations to enhance mass transfer and hydrate formation. This substitution maintains high gas separation efficiency while significantly simplifying the operational conditions and making the process more suitable for industrial application.

AI summary
A disturbance device has two jet mixers, which are oppositely disposed in the horizontal direction; a mixing chamber, which is connected between the two jet mixers; and mixing pipes, which are connected below the mixing chamber. The mixing pipes comprise: a central pipe, which is a vertical straight pipe; multiple helical pipes, which are wound in multiple layers and provided outside the central pipe, the diameters of the multiple helical pipes gradually increasing from the inner to outer layers, and multiple flow deflector assemblies being provided at intervals in each helical pipe; and an outer sleeve, which is a straight pipe, the outer sleeve being sleeved outside the outermost helical pipe. A continuous gas separation system combines a hydrate-based process and a reverse osmosis process, using the disturbance device, enables continuous gas separation.
