Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pressure is reduced to approximate zero bar absolute to extract all gases, then gas removal is improved, but water begins to boil causing excessive energy loss and water vapor release
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the pressure in the reservoir based on temperature measurements. Instead of maintaining a fixed low pressure (approximating zero bar absolute), the system modifies the pressure parameter according to the relationship between temperature and boiling point, ensuring pressure stays above the boiling threshold while still enabling effective gas extraction through controlled pressure reduction cycles.
Solution Approach 2:
The patent implements feedback control by continuously monitoring temperature in the reservoir and using this information to regulate pressure. The control system receives temperature data and adjusts pressure accordingly to maintain the optimal operating window where gas can be extracted without causing water to boil, thereby preventing excessive energy loss and water vapor release.
2Quantity of substance
If pressure is reduced to approximate zero bar absolute to extract all gases, then gas removal is improved, but water vapor is released causing damage to degassers
Solution Approach 1:
The patent changes the pressure parameter dynamically based on temperature conditions. By calculating and maintaining pressure above the boiling threshold corresponding to the reservoir temperature, the system prevents water from vaporizing while still achieving effective gas extraction. This parameter adjustment eliminates water vapor release and its associated damaging effects on the degasser equipment.
Solution Approach 2:
The patent applies preliminary anti-action by proactively controlling pressure to prevent water vaporization before it can occur. The control system anticipates the boiling condition by monitoring temperature and adjusting pressure in advance to stay above the vaporization threshold, thereby preventing the harmful effect of water vapor release before it can damage the equipment.
3Device complexity
If manual control is used for degassing process, then device complexity is reduced, but degassing takes place for unnecessarily long time
Solution Approach 1:
The patent implements automated feedback control by equipping the system with temperature sensors and control logic that continuously monitor reservoir conditions and automatically adjust pressure parameters. This feedback mechanism enables the degassing process to respond dynamically to actual system state, optimizing gas extraction efficiency and reducing the time required compared to manual control, while the added complexity remains manageable through standardized control components.
Solution Approach 2:
The patent replaces manual mechanical control with an automated control system that uses temperature sensing and electronic regulation. This substitution of manual operation with automated measurement and control mechanisms optimizes the degassing process timing while keeping device complexity at an acceptable level through the use of standard sensors and control logic.
4Productivity
If pump capacity is increased to improve degassing speed, then productivity is improved, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the pump operation variable rather than fixed. The control system dynamically adjusts pump running time and capacity based on real-time temperature and pressure conditions in the reservoir. This dynamic control enables the system to achieve high productivity when gas extraction is needed while minimizing energy consumption during periods when degassing is complete or conditions are favorable, optimizing the balance between speed and energy use.

This approach allows for precise and efficient degassing, reducing energy consumption and preventing damage from boiling, while ensuring the system remains free from harmful gas levels, thereby maintaining optimal energy performance and system integrity.
Implementation Method 1
A part of the water at a time from the installation is here isolated in a reservoir in which its pressure is reduced. Making use of Henry's law, the isolated system water is able to absorb fewer gases at this lower pressure.
Implementation Method 2
Because a pump is necessary for this process
Implementation Method 3
The gases released during this pressure step are discharged via a float vent, which is mounted on the reservoir
