Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional measurement probes in gas phase reactors are limited to monitoring conditions near the exterior of the fluidized bed, failing to accurately capture core conditions, leading to uncertainties in computer simulations and model inaccuracies, which hampers catalyst utilization and reactor performance optimization.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement probes are extended deep into the fluidized bed, then measurement precision of core conditions is improved, but device complexity and susceptibility to damage increase
Solution Approach 1:
The measurement system is divided into multiple independent probes, each equipped with multiple sensors at different positions. This segmentation allows the system to obtain comprehensive measurements from various locations in the fluidized bed without requiring a single complex probe to extend deep into the bed, thereby reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The measurement probes are designed to perform multiple functions: measuring temperature, pressure, and electrostatic charge simultaneously. This multi-functionality reduces the need for separate probes for each parameter, simplifying the overall device structure while enabling comprehensive monitoring of core conditions in the fluidized bed.
2Measurement precision
If measurement probes are extended deep into the fluidized bed, then measurement precision of core conditions is improved, but reliability decreases due to probe damage from bubbles and particles
Solution Approach 1:
The probes are equipped with protective measures beforehand to withstand the harsh fluidized bed environment. The probes are designed to resist damage from bubbles and particles, ensuring reliable operation throughout the measurement period without frequent replacement or maintenance, thus maintaining both measurement precision and reliability.
3Measurement precision
If multiple sensors are arranged along the probe, then measurement precision at multiple points is improved, but device complexity increases
Solution Approach 1:
Multiple sensors for different parameters (temperature, pressure, electrostatic charge) are merged into a single integrated probe assembly. This combining approach allows simultaneous measurement at multiple points without requiring separate probe installations, reducing overall device complexity while achieving high measurement precision across the fluidized bed.

AI summary
A fluidization measurement system for a gas phase reactor containing a fluidized bed includes a measurement probe coupled to a sidewall of the gas phase reactor. The measurement probe includes a support bar penetrating the sidewall and extending into the fluidized bed to a distance of at least 12% of a diameter of the gas phase reactor, and a plurality of sensors arranged along a length of the support bar to obtain measurements of at least one of temperature, pressure, and electrostatic charge at multiple points within the fluidized bed. A base plant control system is in communication with measurement probe to receive and process the measurements to determine real-time physical conditions and flow patterns of the fluidized bed.
