Dual-Mode Rectification Pilot Plant for Practical Training Unit Operations

Introduction

The Dual-Mode Rectification Practical Training Unit Operations Pilot Plant is an industrial-scale, two-tier laboratory system designed specifically for chemical engineering and process technology departments in higher education. This pilot plant features a sieve-plate distillation column equipped with visual sight glasses, allowing students to directly observe gas-liquid mass transfer and hydrodynamic phenomena. Integrating a unique dual-mode control system, the unit can operate either in "Real-Material Mode" using actual chemical mixtures with physical sensors and heaters, or in "Simulated-Material Mode" using safe fluids like water or air combined with mathematical models that respond to physical valve manipulations. This dual approach offers universities a flexible, safe, and highly pedagogical tool for teaching mass transfer and separation processes.

To ensure seamless integration with diverse laboratory spaces and syllabus requirements, this pilot plant supports extensive hardware and software customization. Both the physical layout—including column dimensions, material selection, and platform footprints—and the digital control interfaces can be modified to align with the specific training objectives of your institution.

Key Pedagogical Functions and Advantages

• Dual-Operating Modes:
  • Real-Material Mode: The upper computer SCADA software collects real-time data from physical sensors and controls active components like feed pumps and electrical heaters for authentic process operation.
  • Simulated-Material Mode: Allows safe operations using water or air. The system registers physical valve actions and uses integrated mathematical models to simulate corresponding process changes on the control software, enhancing safety while teaching start-up and shutdown procedures.
• Mass Transfer and Efficiency Studies: Supports the determination of overall column and individual plate efficiencies under total or partial reflux conditions. Convenient sampling ports are distributed across all tanks and column stages.
• Visual Hydrodynamic Observation: Built-in sight glasses along the column wall enable students to observe real-world tray behaviors, including bubbling, weeping, and entrainment.
• Variable Feed and Reflux Control: Features adjustable pre-heating systems to analyze the impact of different thermal feed states on separation, alongside manual and automated control of reflux ratios.
• Environmentally Friendly and Cost-Effective: Includes a fluid recycling loop that reduces chemical consumption and minimizes waste generation during repeated training sessions.
• Industrial-Grade Safety Frame: Built on a heavy-duty, two-story steel structure with a 1.2-meter safety handrail, anti-slip checkered steel plates, and an integrated safety ladder, giving students authentic experience in navigating industrial process plants.

Curriculum Integration and Textbook Alignment

This pilot plant is designed to bridge theoretical principles taught in lectures with physical engineering practice. It supports laboratory modules across several majors, including Chemical Engineering, Environmental Engineering, Food Engineering, and Biotechnology.

The experimental capabilities of the unit align directly with core principles found in standard university textbooks, facilitating a cohesive learning environment where students can easily cross-reference their practical observations with academic literature:

By utilizing this pilot plant, professors can easily demonstrate the physical reality behind the equations and diagrams found in these foundational texts, helping students develop a intuitive understanding of process engineering.

Hardware and Software Customization

To accommodate the specific constraints of different university laboratories, we offer tailored adjustments for both hardware and software. Hardware modifications include adjustments to the platform size, staircase orientation, column height, number of sieve trays, and metallurgy selection (such as stainless steel grades). On the software side, the control interface, data-logging parameters, and mathematical simulation models can be customized to match your curriculum's focus, ensuring the equipment fits into your existing laboratory infrastructure.
