Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas liquid separators are prone to unbalanced states due to fixed restrictions, leading to inadequate separation and loss of samples under varying system flow conditions, as they fail to maintain the integrity of the solvent and gas phases.
Innovation Solution
Incorporating sensors to monitor solvent and gas levels within the chamber, coupled with a pressure regulator or on/off valve to adjust pressures and flows, ensuring balanced separation by regulating the solvent and gas levels dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed restrictions are used in conventional gas liquid separators, then the device structure is simple, but the separation becomes unbalanced under varying system flow conditions leading to sample loss
Solution Approach 1:
The patent applies dynamics by replacing fixed restrictions with adjustable flow control valves that can dynamically adapt to varying system flow conditions. The controller receives feedback from level sensors and adjusts the valve positions in real-time to maintain balanced separation between gas and solvent phases, transforming a static system into a dynamic one that responds to changing conditions.
Solution Approach 2:
The patent implements feedback control by using level sensors to continuously monitor the positions of the solvent-gas interface and gas-liquid interface in the separation chamber. The controller processes this feedback information and adjusts the flow control valves to maintain optimal separation balance, ensuring that the separator adapts to varying inlet flow conditions while preventing sample loss.
2Reliability
If manual adjustment is used in conventional gas liquid separators, then the device complexity is low, but the response to varying flow conditions is slow and inadequate
Solution Approach 1:
The patent implements feedback control by using level sensors to continuously monitor the positions of the solvent-gas interface and gas-liquid interface in the separation chamber. The controller processes this feedback information and adjusts the flow control valves to maintain optimal separation balance, ensuring that the separator adapts to varying inlet flow conditions while preventing sample loss.
Solution Approach 2:
The system performs self-service by automatically monitoring its own operational state through level sensors and making self-adjustments via the controller and flow control valves. This eliminates the need for manual intervention while maintaining reliable separation integrity under varying flow conditions, with the system regulating its own flow distribution based on real-time feedback.
3Measurement precision
If no level monitoring is implemented, then the device complexity is minimal, but the separation balance cannot be maintained under varying conditions
Solution Approach 1:
The patent implements feedback control by using level sensors to continuously monitor the positions of the solvent-gas interface and gas-liquid interface in the separation chamber. The controller processes this feedback information and adjusts the flow control valves to maintain optimal separation balance, ensuring that the separator adapts to varying inlet flow conditions while preventing sample loss.
Solution Approach 2:
The patent replaces mechanical level indication methods with electronic level sensors that provide precise measurement of solvent and gas levels. This substitution enables accurate detection and automated control, transforming the system from a purely mechanical operation to one that incorporates electronic sensing and control for enhanced measurement precision.
