Introduction
The Green Anhydrous Ethanol Purification and Extractive Distillation Practical Training Unit Operations Pilot Plant is a modular, pilot-scale laboratory system designed for chemical engineering and related industrial disciplines. The plant processes crude ethanol (approximately 40% concentration) using an ethylene glycol extractive distillation method to produce high-purity anhydrous ethanol. Engineered with a focus on digitalization and environmental sustainability, the system operates on a zero-emission closed-loop process where raw materials and solvents are continuously recycled. This unit provides engineering students and researchers with a realistic, hands-on environment to study complex distillation processes, process control, and green chemical engineering principles.
Customizable Solutions
To meet the specific pedagogical objectives, space constraints, and curriculum requirements of different universities, this pilot plant features a flexible design. Both the hardware configurations and the software management platforms can be fully customized, allowing institutions to tailor the system to their precise laboratory training needs.
Key Teaching Functions and Advantages
- Realistic Engineering Layout: Helps students understand industrial plant zoning concepts, including the arrangement of utility areas, process areas, and main pipe racks, bridging the gap between classroom theory and plant design.
- Modular Process Operations: Organized into distinct modular sections—specifically crude ethanol purification and extractive distillation—reinforcing the concept of industrial unit operations and process sequencing.
- Closed-Loop Green Technology: Built with a materials-recycling design that achieves zero emissions during normal operation, fostering environmental awareness and sustainable engineering practices.
- Advanced Process Control & Instrumentation: Integrates industry-standard sensors and instruments (temperature, pressure, flow rate, liquid level, and agitation speed). Students gain practical experience in sensor calibration, operation, and troubleshooting.
- Dual Control Architecture: Supports both manual local control and automated remote monitoring through a distributed control configuration, allowing students to practice PLC configuration, process visualization, and real-time alarm management.
- Safety and Collaborative Operations: Promotes teamwork through co-operative control room and field operation scenarios, cultivating industrial safety awareness and standard operating procedures (SOPs).
