Advisory System for Gas Treating Solvent Quality Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In amine gas treating processes, solvent quality can deteriorate due to vaporization, entrainment, and other losses, leading to changes in solvent volume and composition if not monitored and corrected.
Innovation Solution
An advisory system for continuous monitoring of the gas treating system calculates a water content deficit and determines a water makeup rate to compensate, displaying this information through an interactive user interface to maintain solvent quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous monitoring and calculation of water content deficit is implemented, then solvent quality is maintained, but system complexity increases
Solution Approach 1:
The system continuously monitors solvent water content and provides feedback through calculated deficit values and makeup rate recommendations, enabling dynamic adjustment to maintain solvent quality within specified ranges despite vaporization and entrainment losses
Solution Approach 2:
The advisory system automatically calculates water content deficit and determines appropriate makeup rates based on monitored parameters, reducing the need for manual intervention and expert judgment while maintaining reliable solvent quality control
2Stability of the object's composition
If water makeup rate is continuously adjusted to compensate for vaporization losses, then solvent composition is maintained, but energy consumption increases
Solution Approach 1:
The system calculates water content deficit and determines makeup rates in advance based on predicted vaporization losses from overhead streams, allowing proactive maintenance of solvent composition rather than reactive correction, which reduces energy-intensive make-up operations
Solution Approach 2:
The advisory system provides targeted water makeup recommendations based on calculated deficits rather than continuous full-rate makeup, applying only the necessary amount to maintain composition stability and reduce unnecessary energy consumption

AI summary
A method for maintaining solvent quality in a gas treating system involves calculating, by an advisory system for continuous monitoring of the gas treating system, a water content deficit in the solvent of the gas treating system, calculating, by the advisory system, a water makeup rate compensating for the water content deficit, and displaying, in an interactive user interface of the advisory system, the water makeup rate.
