Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capturing and storing carbon dioxide emissions from small point sources like carbon/carbon (C/C) preform production processes is costly and logistically challenging due to the high energy input required for underground sequestration, making traditional methods economically unviable.
Innovation Solution
A system that converts carbon dioxide into methane through a methanization reaction using hydrogen generated during the C/C preform production process, supplemented with green hydrogen, and recycles water back into a steam generator, integrating a reformer to produce hydrogen and carbon monoxide for the methanization reactor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional underground CO2 sequestration methods are used, then CO2 emissions are captured and stored, but the logistical and energy costs become prohibitively high for small point sources
Solution Approach 1:
The patent converts harmful CO2 emissions into beneficial methane fuel through the methanization reaction (CO2 + 4H2 → CH4 + 2H2O). This chemical transformation turns the waste product into a useful energy carrier that can be fed back into the production process, eliminating the need for expensive sequestration while providing energy benefits
Solution Approach 2:
The system uses its own CO2 emissions and hydrogen production as inputs for methanization, creating a self-sustaining loop where the process waste becomes the fuel source. The produced methane is then fed back into the C/C preform production process, making the system energy-self-sufficient and eliminating external energy inputs for CO2 management
2Object-affected harmful factors
If CO2 emissions are captured and stored through traditional methods, then emissions are managed, but the logistical complexity and costs increase significantly
Solution Approach 1:
The patent merges the CO2 management function with the energy production function by integrating the methanization reactor into the existing C/C preform production system. The CO2 capture, conversion, and utilization occur within a single integrated system rather than requiring separate capture and sequestration infrastructure, dramatically simplifying logistics
Solution Approach 2:
The methanization reactor serves as an intermediary device that transforms CO2 into methane, which then acts as a mediator to transfer energy back into the production process. This intermediary approach eliminates the need for direct CO2 sequestration infrastructure while achieving emission management through productive utilization
3Loss of substance
If hydrogen is produced during C/C preform production, then a valuable byproduct is generated, but it needs to be utilized effectively to achieve sustainability goals
Solution Approach 1:
Instead of discarding the hydrogen byproduct, the system recovers it through the methanization reaction where hydrogen combines with CO2 to produce methane. This recovered methane is then fed back into the production process as fuel, transforming a waste stream into a valuable energy resource that supports sustainability objectives
