Introduction
The o-Xylene Oxidation to Phthalic Anhydride Educational Unit Operations Pilot Plant is a specialized, bench-scale laboratory system designed for university-level engineering instruction. It provides students with hands-on experience in gas-phase catalytic oxidation within a fixed-bed tubular reactor. By simulating the industrial-scale synthesis of phthalic anhydride from o-xylene, this pilot plant helps bridge the gap between theoretical chemical reaction kinetics and practical process operations.
To ensure compatibility with diverse academic curricula and laboratory spaces, both the hardware components and the software interface of this pilot plant can be fully customized to meet specific institutional requirements.
Key Pedagogical Features and Advantages
This educational pilot plant is designed to optimize laboratory instruction while providing students with practical exposure to industrial process conditions:
- Process Visualization: The high-temperature glass reactor allows students to visually inspect the catalyst bed, observe physical changes during the reaction, and monitor the behavior of the reactants in real time.
- Industrial Process Simulation: Demonstrates a classic, highly exothermic industrial reaction, teaching students how to manage heat transfer and temperature profiles in packed-bed reactors.
- Advanced Instrumentation: Equipped with precise sensors for temperature and pressure, alongside an integrated touch-screen control panel, facilitating quantitative data collection for kinetic analysis.
- Inherent Process Safety: Built-in safety features include automated over-temperature alarms, an integrated air filtration system, and a 5L stainless steel buffer tank to stabilize pressure fluctuations.
- Operational Mobility: Mounted on a durable aluminum alloy frame with lockable casters, allowing the unit to be easily relocated or reconfigured within the laboratory space.
