Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring and managing reactive emissions from hydrocarbon production systems, such as wellheads and artificial lifts, are inflexible and can lead to delayed leak detection, costly repairs, and legal fines due to periodic testing regimens, which may not promptly identify or mitigate emissions before they escape into the environment.
Innovation Solution
An emissions monitoring and management system comprising a containment assembly with a fluid conduit, emissions conditioner, detectors, and a transmitter that captures and treats emissions from industrial components, providing real-time monitoring and mitigation capabilities to reduce the concentration of hazardous gases like methane and VOCs before they escape into the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If periodic testing is used to monitor emissions, then device complexity is reduced, but detection speed and response time deteriorate
Solution Approach 1:
The patent replaces manual periodic testing with automated electronic detection systems including sensors, transmitters, and control units that continuously monitor emissions without requiring physical intervention, thereby maintaining simplicity while dramatically improving detection speed
Solution Approach 2:
The system implements continuous monitoring through constantly active sensors and transmitters that operate without interruption between testing intervals, ensuring emissions are detected immediately upon release rather than waiting for periodic inspection cycles
2Productivity
If periodic testing intervals are extended to reduce monitoring frequency, then loss of time for repairs increases, but productivity is improved
Solution Approach 1:
The system incorporates feedback loops where sensor data is continuously transmitted to control units that immediately trigger alerts when emissions thresholds are exceeded, enabling real-time response to leaks rather than waiting for scheduled inspection intervals
Solution Approach 2:
The continuous monitoring system detects emissions at the earliest stages of leakage, enabling preventive maintenance actions to be taken before leaks escalate into major environmental incidents or require costly emergency repairs
3Object-affected harmful factors
If containment assembly is made sealed to prevent emission escape, then environmental protection is improved, but device complexity and cost increase
Solution Approach 1:
The system introduces a fluid conduit as an intermediary pathway that channels emissions from the containment assembly to a treatment device, allowing the containment structure to remain relatively simple while still achieving environmental protection through controlled emission routing and treatment
Solution Approach 2:
The system extracts emissions from the containment assembly through dedicated fluid conduits and routing systems, separating the containment function from the emission treatment function, thereby simplifying the containment structure while maintaining environmental protection
4Speed
If real-time monitoring is implemented to improve leak detection speed, then detection speed is improved, but device complexity and cost increase
Solution Approach 1:
The monitoring system is segmented into discrete, modular components including individual sensors for different gas types, separate transmitter units, and distributed control elements, allowing the system to achieve comprehensive real-time monitoring while maintaining manageable complexity through modular architecture
