The PMMA 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 enhancing operational safety. The system supports both flexible manual operation and intelligent PLC automatic control modes to meet the needs of different users.
Superior Advantages of Vacuum Distillation Technology
Lower Boiling Point, Energy Efficiency
By maintaining a vacuum pressure of 10-50 kPa (absolute pressure), 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.
Equipment Parameters and Advanced Operating Modes
Components Technical Specifications
Distillation Tower Material
Acrylic rectification tower is made of 304 stainless steel, offering excellent resistance to MMA corrosion and vacuum pressure withstand capability (design pressure resistance -0.1 MPa).
Vacuum System Configuration
Integrates a high-performance vacuum pump (ultimate vacuum up to 5 kPa) and a buffer tank to ensure a continuous and stable vacuum environment.
Control System
Supports PLC intelligent control for automated operation and monitoring.
How to Operate the MMA Rectification Tower?
● 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 that 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.
