Facility Emission Control via Correlated Asset Set Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing process control systems in facilities do not integrate emission management, leading to excessive emissions that violate regulatory limits, resulting in compliance issues, penalties, and negative environmental and health impacts.
Innovation Solution
A method that integrates emission management with process control systems by identifying set points for assets, determining emission levels, correlating emissions across assets, and implementing corrective actions to reduce emissions below predefined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If process control systems operate assets based on throughput set points, then productivity is improved, but emission levels exceed regulatory limits
Solution Approach 1:
The system implements a feedback mechanism where emission levels are continuously monitored and fed back to the process control system. When emissions approach regulatory limits, the system automatically adjusts asset set points to reduce emissions while maintaining acceptable throughput levels, creating a closed-loop control that balances productivity with environmental compliance
Solution Approach 2:
The system dynamically changes operating parameters (set points) of assets based on real-time emission levels. When emissions are high, the system adjusts parameters such as production rates, temperature, or pressure to reduce emissions. This allows the facility to operate at optimal efficiency when emissions are low and automatically reduce output when emissions approach limits, resolving the contradiction between maintaining productivity and controlling emissions
2Productivity
If process control systems focus on throughput optimization, then productivity is improved, but compliance with emission regulations deteriorates
Solution Approach 1:
The system integrates emission monitoring feedback into the process control architecture, creating a dual-objective control system that simultaneously tracks both throughput and emission levels. This feedback loop ensures regulatory compliance by automatically alerting operators and adjusting operations when emissions approach regulatory thresholds, thereby maintaining both productivity and compliance reliability
Solution Approach 2:
The system takes preliminary action by establishing emission thresholds and compliance criteria before operations begin. The control system is pre-configured with regulatory limits and automatically prevents operations that would lead to non-compliance, rather than reacting after violations occur. This proactive approach ensures continuous regulatory compliance while maintaining productivity
3Object-generated harmful factors
If emission monitoring and control integration is implemented, then emission compliance is improved, but system complexity increases
Solution Approach 1:
The system merges emission monitoring and control functions with the existing process control infrastructure rather than implementing separate standalone systems. By integrating emission sensors, analytics, and control actions into the current SCADA or DCS platform, the system achieves comprehensive emission management while minimizing additional complexity through shared hardware and software resources
Solution Approach 2:
The emission control system is designed with multi-functionality to handle various emission types (CO2, CH4, N2O, etc.), multiple assets, and different regulatory requirements through a single unified platform. This universal approach consolidates what could be multiple separate systems into one versatile system, reducing overall complexity while maintaining comprehensive emission control capabilities

AI summary
Various embodiments described herein relate to systems and methods for managing emissions in a facility. In this regard, a set point at which each asset of a plurality of assets is operating in the facility is determined. An emission level associated with each asset of the plurality of assets is determined as well. The emission level associated with each of the plurality of assets is correlated to determine if the correlated emission level exceeds a predefined threshold. If the correlated emission level exceeds the predefined threshold, one or more corrective actions for at least one asset is identified. Also, the one or more corrective actions are rendered on a display. An input is received from an operator that corresponds to a selection of one of a corrective action. Based on the corrective action, the at least one asset is operated at a first set point different from the set point.
