AI Technical Summary
Existing distillation units are unable to effectively separate high-boiling-point components and heat-sensitive components from complex materials, resulting in mixed components, low separation efficiency, and a lack of pretreatment functions, leading to high bottom load, high energy consumption, and inaccurate reflux control, which affects the separation quality.
The system employs a combined control approach of in-tower fractionation, condensation reflux, evaporation pretreatment, and multi-point feeding. Through a multi-stage feeding structure, evaporation device, and condensation reflux system, it achieves efficient separation of light and heavy components and heat recovery. Precise reflux control is achieved by combining flow meters and regulating valves.
It improves distillation efficiency, reduces energy consumption, enhances the applicability and process flexibility of the equipment, and ensures operational stability and safety.
