List of Operating Principles for Distillation Equipment

List of Operating Principles for Distillation Equipment

I. Core Process

A distillation kettle system that operates primarily under normal pressure, with vacuum distillation as an auxiliary, and is equipped with a preheating device

II. Equipment Components

Main distillation kettle

Supporting units: packed tower, tube bundle cooling system, negative pressure station, sand filter unit, oil blending unit, fume treatment system

III. Functions of the Preheating Device

Energy Saving & Efficiency Improvement: Recovers waste heat generated from heating the distillation kettle to preheat waste engine oil, enhancing the utilization rate of fuel heat value

Equipment Protection: Evaporates moisture in waste engine oil to prevent damage to the molecular sieves in the packed tower

IV. Oil Purification Process

Two-stage filtration via sand filter unit and tubular filter to trap suspended impurities in the oil, ensuring oil quality
