Three-way azeotropic distillation
Thread Content
Now a continuous glass distillation tower is needed for scientific research. The design idea is to use cyclohexane as an entrainer and 95% ethanol as raw material to prepare absolute ethanol. The azeotropic point of the ternary azeotrope cyclohexane-ethanol-water is 62.1oC, and the boiling point of ethanol is 78.5oC. The design requirements are that the tower height is about 1.5m, the discharge volume can reach 500ml/h, and the ethanol purity can reach more than 99.95%. Can it meet the requirements? Expert guidance
This depends on the diameter of the tower, what type of packing to use, how to segment the packing, and the liquid collection and redistribution between the packing sections, etc.? It is recommended to use stainless steel as the equipment is easier to process.
The first thing I made was the experimental device, with a tower diameter of 30, about 1500mm, and high-efficiency wire mesh packing.
In fact, there is no need to conduct experiments for azeotropic distillation of anhydrous ethanol, just do the engineering design directly. 1500mm can meet the requirements.
The production of anhydrous alcohol by azeotropic method is very mature in industry, and the general output is less than 50,000.； Choose a float valve for the tower, generally without packing! For more than 50,000 tons, the molecular sieve phase change adsorption method is generally chosen. 1 If the dosage is for scientific research or laboratory use, you can contact Guangdong Zhongke Tianyuan!
