Acrylic Distillation Column

This Acrylic distillation column utilizes advanced vacuum distillation technology, specifically designed for the efficient purification of PMMA pyrolysis solutions. It stably produces MMA monomer solutions with a purity of 96% or higher, while significantly reducing energy consumption and improving operational safety. The system supports both flexible manual operation and intelligent PLC automatic control modes to meet the needs of different users.

Lower Boiling Point, Energy Efficiency

By maintaining a vacuum state of 10-50 kPa (absolute pressure) in the system, the boiling point of MMA is significantly reduced from 100.5°C at atmospheric pressure to 60-80°C. This innovative design not only significantly reduces heating energy consumption (approximately 25% energy saving compared to atmospheric pressure distillation) but also effectively avoids potential thermal decomposition or polymerization reactions of MMA under high-temperature conditions, ensuring product purity and quality.

Enhanced Safety and Energy Efficiency

Vacuum Explosion-Proof Design: The entire system operates under negative pressure and is equipped with a precise pressure interlock protection device, further enhancing operational safety.

Components | Technical Specifications

● Distillation Column Material: 304 stainless steel, offering excellent resistance to MMA corrosion and vacuum pressure withstand capability (design pressure resistance -0.1 MPa)

● Vacuum System Configuration: Integrated high-performance vacuum pump (ultimate vacuum up to 5 kPa) and buffer tank, ensuring a continuous and stable vacuum environment.

● Control System: Supports PLC intelligent control for automated operation and monitoring.

● Manual Operation Mode: Users can intuitively adjust the vacuum level and reflux ratio for flexible operation control.

● PLC Automatic Operation Mode: The system has a preset optimized pressure-temperature curve that automatically compensates for feed fluctuations, ensuring the purity of the MMA product always meets standards. This mode not only simplifies the operation process but also significantly improves production efficiency and product quality stability.
