Stainless Steel Distillation Columns
Stainless steel distillation columns are core equipment for separating and purifying liquid mixtures based on differences in the boiling points of substances. They enhance gas-liquid mass transfer through internal packings or trays, and obtain high-purity components via a cyclic process of heating vaporization and condensation reflux. Made of 304 or 316L stainless steel, they resist corrosion from acids, alkalis and organic solvents. Their surfaces undergo polishing treatment for easy cleaning, meeting food-grade and GMP standards.
Product Details
The equipment is widely used in multiple fields: the chemical industry for purifying solvents like ethanol and acetone; the pharmaceutical industry for refining API intermediates; the food industry for processing essences and plant extracts; and the petrochemical industry for light hydrocarbon separation.
Specifications cover multiple models. The still volume ranges from 1L to 100L, the column diameter from DN50 to DN100, and the standard height is 1000mm (customizable). Equipped with a reflux ratio controller and a temperature control system, they support atmospheric or vacuum operation. Control types include ordinary, explosion-proof and PLC control, adapting to different production needs.
