Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems for CO2 recovery require additional equipment, increased power consumption, and inconvenient long vehicle stops for desorption and CO2 extraction, making them impractical for efficient CO2 removal.
Innovation Solution
A vehicle configuration with a CO2 recovery container and adsorbent storage system that allows for the removal and replacement of adsorbents outside the vehicle, using a supply and discharge passage system to efficiently extract and replenish adsorbents, enabling CO2 desorption without the need for on-vehicle heating or pressure reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If heating or pressure reduction is applied to make CO2 desorb from the adsorbent in the vehicle, then CO2 can be recovered, but additional equipment and power consumption increase
Solution Approach 1:
The adsorbent is extracted from the vehicle and taken out to an external facility for CO2 desorption and recovery. This extraction allows the desorption process to occur outside the vehicle using external equipment, thereby avoiding the need for additional on-vehicle equipment and reducing power consumption within the vehicle system.
2Quantity of substance
If heating or pressure reduction is applied to make CO2 desorb from the adsorbent in the vehicle, then CO2 can be recovered, but additional equipment is required
Solution Approach 1:
The adsorbent is extracted from the vehicle and taken out to an external facility for CO2 desorption and recovery. This extraction allows the desorption process to occur outside the vehicle using external equipment, thereby avoiding the need for additional on-vehicle equipment and reducing power consumption within the vehicle system.
3Quantity of substance
If the vehicle stops for a long period to make CO2 desorb from the adsorbent and take it out, then CO2 can be recovered, but convenience is lowered
Solution Approach 1:
The adsorbent is preliminarily loaded into the vehicle before departure at a service station. This preliminary action allows the adsorbent to be in place and ready for CO2 adsorption during the vehicle's operation, eliminating the need for long stoppages during normal operation for adsorbent replacement or CO2 recovery.
Solution Approach 2:
The adsorbent is extracted from the vehicle and taken out to an external facility for CO2 desorption and recovery. This extraction allows the desorption process to occur outside the vehicle using external equipment, thereby avoiding the need for long vehicle stoppages and maintaining convenience during normal operation.
4Productivity
If adsorbent is continuously supplied and removed from the vehicle, then CO2 recovery efficiency is improved, but system complexity increases
Solution Approach 1:
The CO2 recovery system is segmented into separate functional components: a CO2 recovery container for adsorption during vehicle operation, and an external facility for desorption and adsorbent regeneration. This segmentation allows continuous operation of the vehicle's CO2 recovery function while the adsorbent is regenerated externally, improving overall efficiency without requiring complex integrated systems.
Solution Approach 2:
The adsorbent acts as an intermediary carrier that is temporarily loaded into the vehicle for CO2 adsorption and then removed for regeneration. This intermediary approach allows the separation of adsorption and desorption processes in both space and time, simplifying the overall system architecture while maintaining continuous CO2 recovery capability.
