Solution Overview
Problem
Existing systems are inadequate for efficiently processing large volumes of methane gas and capturing excess heat generated by catalytic heaters in natural gas systems, including wellheads and other applications where methane is vented to the atmosphere.
Innovation Solution
An emission reduction system with a housing containing a first and second catalytic heater, each inclined at a predetermined angle, and a thermal energy conversion module between them, which converts excess heat into usable energy for tasks like heating surfaces or equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single catalytic heater is used to process methane gas, then the system structure is simple, but the processing capacity for large volumes of methane is insufficient
Solution Approach 1:
The patent divides the single catalytic heater into multiple independent catalytic heaters (first catalytic heater and second catalytic heater), each capable of processing methane gas separately. This segmentation increases the overall processing capacity while maintaining modular simplicity in each individual unit.
Solution Approach 2:
The patent combines multiple catalytic heaters within a single housing structure, integrating them into one system. This merging approach increases total methane processing capacity while sharing common infrastructure (housing, gas distribution system), thereby limiting the increase in overall system complexity.
2Object-generated harmful factors
If catalytic heaters are used to oxidize methane, then methane emissions are reduced, but excess heat is generated that is not utilized
Solution Approach 1:
The patent captures the excess heat generated by the catalytic heaters and redirects it through heat exchangers to perform useful functions such as heating water or air. This converts the previously wasted thermal energy into a beneficial resource, simultaneously maintaining methane oxidation effectiveness and reducing energy loss.
Solution Approach 2:
The patent implements a heat recovery system that captures thermal energy from the catalytic heaters before the exhaust gases are released. The recovered heat is stored or utilized for other purposes, preventing its dissipation into the environment and improving overall system efficiency.
3Ease of manufacture
If catalytic heaters are positioned vertically, then installation is simple, but heat capture efficiency is reduced
Solution Approach 1:
The patent makes the catalytic heaters adjustable in orientation, allowing them to be positioned at various angles relative to vertical. This dynamic positioning capability enables optimization of heat capture efficiency by directing hot gases toward heat exchangers while still allowing for simple vertical installation when needed, adapting to different operational requirements.
