Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reactors for oxidizing organic and inorganic materials in aqueous fluids at elevated pressure and temperature face challenges in terms of high production and maintenance costs, as well as corrosion issues due to supercritical conditions and highly corrosive by-products, requiring expensive and specialized materials.
Innovation Solution
The reactor design includes an elongate tubular element with an inner and outer cavity, utilizing a flush fluid connection to prevent corrosive fluids from contacting the reactor body, allowing for the use of less expensive materials and reducing maintenance needs by minimizing contact between the corrosive fluids and the reactor walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reactor body is made from expensive and specialized corrosion-resistant materials to withstand supercritical conditions and corrosive by-products, then the reliability and corrosion resistance are improved, but the production cost increases
Solution Approach 1:
The reactor is divided into two separate cavities: an inner cavity that contacts the corrosive aqueous fluid and an outer cavity that contains flush fluid. This segmentation allows different material requirements for each cavity, with only the inner cavity requiring specialized corrosion-resistant materials, thereby reducing overall production costs while maintaining reliability where needed.
Solution Approach 2:
A flush fluid (inert gas or liquid) is introduced into the outer cavity to act as an intermediary barrier. This flush fluid prevents direct contact between the corrosive aqueous fluid in the inner cavity and the reactor body walls, reducing corrosion and allowing the use of less expensive materials for the reactor body while maintaining reliability.
2Duration of action of stationary object
If the reactor body is made from expensive and specialized corrosion-resistant materials to withstand supercritical conditions and corrosive by-products, then the durability and service life are improved, but the maintenance cost increases
Solution Approach 1:
The flush fluid in the outer cavity serves as a protective intermediary that reduces corrosion of the reactor body, extending its service life. By minimizing direct contact between corrosive fluids and the reactor body, the need for frequent maintenance and replacement is reduced, thereby lowering maintenance costs while improving durability.
3Device complexity
If the reactor body is designed to directly contain the aqueous fluid at elevated pressure and temperature, then the device complexity is reduced, but the corrosion damage increases
Solution Approach 1:
The reactor body is segmented into an inner cavity and an outer cavity separated by a wall. The inner cavity contains the corrosive aqueous fluid while the outer cavity contains the protective flush fluid. This segmentation increases structural complexity but significantly reduces corrosion damage to the reactor body, trading moderate complexity increase for substantial corrosion protection.
Solution Approach 2:
The flush fluid in the outer cavity acts as an intermediary protective layer between the corrosive aqueous fluid and the reactor body walls. This intermediary reduces corrosion damage while the dual-cavity structure manages the added complexity through organized fluid separation and flow paths.
