Sub-boiling Distillation

Sub-Boiling Distillation: The Optimal Method for Acid Purification and Cleaning

Sub-boiling distillation has been proven to be the most effective method for acid purification and acid cleaning. This advanced purification technique utilizes specialized heaters to vaporize liquid at a temperature typically 5–20°C below its boiling point.

Unlike conventional distillation, where acid boiling produces aerosolized particles that contaminate the distillate, sub-boiling distillation relies on gentle surface evaporation. This process eliminates spray or droplet formation, ensuring the production of ultra-high-purity acids essential for critical applications.

 

To achieve the highest purity in acid purification, the acid temperature must be meticulously controlled below its boiling point, allowing gentle vaporization under sub-boiling conditions.

Maximizing the efficiency of an acid purifier or acid steam cleaner depends on the accurate detection and regulation of the acid’s actual temperature. Precise thermal control ensures optimal sub-boiling distillation performance, preventing contamination and maintaining ultra-high purity levels.

The boiling point of hydrochloric acid depends on its concentration. A 20% solution of hydrochloric acid has a boiling point of about 110 °C (230 °F), while a 38% solution has a boiling point of about 149 °C (300 °F). These boiling points are higher than those of pure water because of the presence of the HCl molecule and its interactions with water molecules.
