As one of the most dynamic fields in today’s chemical industry, fine chemical engineering is characterized by diverse product types, high added value, a wide range of applications, and strong industrial relevance. Therefore, mastering the process operations of fine chemical engineering constitutes an important component of teaching.
Green Anhydrous Ethanol Refining Practice Device
Absolute ethanol is an important basic organic chemical raw material. The ethylene glycol-based extractive distillation method for producing absolute ethanol overcomes the shortcomings of many traditional processes and enables the preparation of absolute ethanol in arbitrary proportions and scales. The green absolute ethanol refining practice device uses crude ethanol (approximately 40% concentration) as raw material and employs the ethylene glycol extractive distillation method to produce absolute ethanol. The device is equipped with a crude ethanol refining tower, an extractive distillation tower, and an ethylene glycol solvent recovery tower. During the experimental process, the three towers operate simultaneously to achieve repeated use of the solvent. Additionally, the equipment piping follows an industrial actual production piping scheme, which prevents unqualified products from flowing into subsequent sections. Once the equipment stabilizes, continuous cyclic use of the experimental raw materials and extractant can be achieved.
