Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for separating multiphase fluids, such as oil and water, in hydrocarbon processing plants are inefficient and often rely on gravity or coalescence, which are not effective for all conditions and require multiple stages or complex designs.
Innovation Solution
A phase separation reactor equipped with a switchable separation layer that can be oleophilic/hydrophobic or oleophobic/hydrophilic, allowing for efficient separation of oil and water phases based on pH conditions, enabling the same reactor to be used for both oil and water separation by switching its surface properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional gravity separation or coalescence methods are used, then oil-water separation can be achieved, but the process requires multiple stages or complex designs and is not effective for all conditions
Solution Approach 1:
The patent applies parameter changes by utilizing pH-responsive materials that switch their surface properties (oleophilic/hydrophobic or oleophobic/hydrophilic) based on pH conditions. This allows a single separation stage to adapt its separation mechanism according to the fluid conditions, eliminating the need for multiple fixed-stage designs while maintaining high separation effectiveness across varying oil-water emulsion conditions.
Solution Approach 2:
The invention implements dynamics through switchable separation layers that can dynamically change their surface characteristics in response to pH changes. This dynamic adaptation enables the same reactor to handle different types of oil-water separations (oil-through or water-through modes) without requiring multiple static separation stages, thereby reducing device complexity while improving reliability.
2Device complexity
If a single separation stage is used, then device complexity is reduced, but separation effectiveness for all conditions is limited
Solution Approach 1:
The patent achieves universality through a single separation stage equipped with pH-responsive switchable materials that can perform multiple separation functions. By adjusting pH conditions, the same separation layer can operate in different modes (oleophilic or hydrophobic), making the single-stage device universally effective for various oil-water separation conditions without requiring multiple specialized stages.
Solution Approach 2:
The invention uses parameter changes (pH adjustment) to enable a single separation stage to adapt its separation characteristics. The pH-responsive materials change their surface properties based on pH conditions, allowing one stage to achieve separation effectiveness that would traditionally require multiple stages with different configurations.
3Adaptability or versatility
If pH-responsive switchable materials are used, then a single reactor can perform both oil and water separation, but material complexity increases
Solution Approach 1:
The patent employs parameter changes by using pH-responsive materials that alter their surface properties in response to pH conditions. This allows the separation layer to switch between oleophilic and hydrophobic modes using a simple pH adjustment parameter, achieving high adaptability without significantly increasing overall device complexity. The material complexity is managed by selecting from known pH-responsive material classes.

AI summary
A phase separator apparatus includes a fluid flow pathway and a phase separator. The fluid flow pathway includes a fluid inlet and a fluid outlet. The fluid flow pathway is configured to flow multiphase fluid including an oil phase and a water phase from the fluid inlet to the fluid outlet. The phase separator is spatially positioned relative to the fluid flow pathway to receive the multiphase fluid flowing from the fluid outlet. The phase separator includes a mounting substrate and a separation layer attached to the mounting substrate. The separation layer includes a material switchable between oleophilic and hydrophobic under a first condition and oleophobic and hydrophilic under a second condition. The separation layer is configured to separate the oil phase and the water phase when the separation layer is under either the first condition or the second condition.
