A short-path (molecular) distiller is a high-vacuum distillation device that enables continuous liquid-liquid separation of materials at temperatures far below their boiling points under extremely high vacuum conditions (absolute pressure < 1 Pa). It features a high heat transfer coefficient, high evaporation intensity, and short residence time, making it particularly suitable for the evaporation and concentration, degassing and desolventization, as well as distillation purification of heat-sensitive materials, highly viscous materials, and materials containing solid particles. Compared to traditional separation methods, molecular distillation offers the following advantages: a) extremely low pressure loss; b) lower evaporation temperatures and shorter heating times; c) high overall heat transfer coefficients and high evaporation efficiency; d) strong adaptability, enabling the processing of high-viscosity solutions containing solids; e) great operational flexibility, facilitating automated operation. Key application areas include: the pharmaceutical industry – vitamins, antibiotics, pharmaceutical intermediates, and pharmaceutical solvents; the personal care industry – fatty acids, glycerin, lecithin, fragrances, and certain surfactants; the organic chemical industry – synthetic resins, synthetic fibers, polyformaldehyde, furans, bisphenol A, etc.; the inorganic chemical industry – tungstic acid, phase salts, potassium (sodium) bromide, potassium carbonate, sodium hydroxide, etc.; the agrochemical industry – insecticides, acaricides, chlorpyrifos, furanols, acetochlor, propachlor, etc.; and environmental protection projects – recycling of used engine oil, treatment of sodium sulfate-containing wastewater, sodium chloride-containing wastewater, etc. Sichuan Jiuyuan Chemical Technology Co., Ltd. (hereinafter referred to as Jiuyuan Chemical or the Company) was established in 2004 with a registered capital of 35 million yuan. It is a high-tech enterprise that has transitioned from military to civilian use; it is under the actual control of the China Academy of Engineering Physics and is controlled by Sichuan Jiuyuan Investment Holding Group Co., Ltd. The company specializes in the research, development, design, manufacturing, and sales of intelligent separation equipment, as well as in the process design for separation projects and the general contracting of such projects. Leveraging the strong research capabilities of the China Academy of Engineering Physics, and based on new separation technologies as its core principle, the company has been dedicated for a long time to the research and process development of various techniques for separating liquid mixtures, such as molecular distillation, falling film evaporation, high-efficiency distillation, multi-effect evaporation, MVR distillation, supergravity distillation, and vaporized film distillation. It has successfully developed process packages and comprehensive industry solutions with independent intellectual property rights, including those for the recycling and regeneration of liquid crystal panel stripping fluids, the distillation of isopropanol aqueous solutions, the distillation of methanol aqueous solutions, the recycling and regeneration of mineral oils, the refining of Fischer-Tropsch waxes, the refining of fish oil ethyl esters, the harmless treatment of highly toxic organic wastewater, and the production of biodiesel. http://www.forever-mem.com.cn/
