The scrubber blowdown is an aqueous waste with an IPA concentration of ~3% (70,000 – 80,000mg/L COD) that cannot be reused on-site or discharged to the The present invention relates to a novel process for producing isopropyl alcohol and isopropyl alcohol with reduced impurities. The propane dehydrogenation process is similar to Lummus CATOFIN, while the propylene hydration is based on a conventional vapor-phase technology. At this time, Isopropanol was generated through the indirect hydration of propylene, a process that uses sulfuric acid to react with Nov 28, 2024 · The effect of isopropyl alcohol on the surface-active characteristics of SAFOL 23 nonionic surfactants was explored. K. Apr 26, 2023 · When embarking on the process design and control of a 99. The May 3, 2022 · Currently, three methods are mainly utilized in Acetone production, and they are as follows: The Isopropyl Alcohol’s dehydrogenation process, Polypropylene’s oxidation process, and Cumene process. Isopropyl alcohol (also called 2-propanol) has a property of dissolving both water and organic solvents, and is widely used as a solvent for paints and inks. Our cumene technology produces a high yield, highly energy eficient, and low environmental impact process. You can easily find it in pharmacies or supermarkets, but have you ever wondered how to make isopropyl alcohol yourself? In this article, we will provide you with a step-by-step guide to create this useful substance at home, along with The global Isopropyl Alcohol (IPA) market has expanded to reach approximately 3308 thousand tonnes in 2024 and is anticipated to grow at an impressive CAGR of 3. Material and energy balances are also developed for the reactor and separation section. A process is disclosed for the production of aliphatic alcohol by the direct hydration of an olefinic hydrocarbon. The heavy-boiling entrainer used to aid the separation is dimethyl sulfoxide (DMSO). k. html) 18. 1). The advantages, limitations, and Aug 5, 2025 · This study presents a comprehensive design, optimization, and intensification approach for enhancing the energy efficiency of electric grade isopropyl alcohol (IPA) production, a typical energy Introduction In the isopropyl alcohol (IPA) to acetone process, both water and IPA are fed through a series of heat exchangers into a plugged flow reactor (PFR) where the endothermic reaction of the dehydrogenation of IPA occurs. Summary Extraction distillation and azeotropic distillation are two important methods for separating isopropyl alcohol (IPA) and water azeotrope. From medical applications to electronic component manufacturing, the use of IPA ensures a clean and sterile environment for both products and consumers. Download scientific diagram | 5 Flow diagram of Tokuyama Process for the production of isopropyl Alcohol 50 tons/day [5] from publication: Efficient and Cost-effective Production of Isopropyl Aug 1, 2017 · With the aim of minimizing the capital and operating cost, Chua et al. T. The catalyst has been tested and qualified to produce IPA through hydrogenation of acetone. In this work, a systematic design, optimization and control procedure is proposed for extractive distillation of heterogeneous mixtures with four azeotropes. 521 License CC BY 4. It is widely used as a solvent in many industries and finds applications in food processing, coatings to reduce flammability, as thinner and additive in paints, as well as disinfectants such as alcohol wipes in Molecular sieve technology is the preferred option to perform isopropyl alcohol dehydration below the azeotropic distillation limits. Which percentage do I need to clean devices? What can it damage? How dangerous is it? These and other questions about isopropyl alcohol, answered. 2 Process technology (Figure 18. Isopropanol, 2-Propanol) is a colorless and flammable liquid with a strong odor. Catalytic hydrogenation is accomplished by reacting acetone with hydrogen gas under high pressure and in the presence of Apr 15, 2022 · Ethyl acetate-isopropyl alcohol-water is a common ternary mixture in pharmaceutical and chemical industries, containing multiple binary minimum azeotropes. The introduction covers the physical and chemical properties of isopropyl alcohol and discusses its production, uses, health and safety factors. In the concept under analysis, propane is dehydrogenated in fixed Badger Cumene Badger Cumene technology has gained worldwide acceptance as the standard for production of cumene. The suitable entrainer 12 Alcohol: Production by Fermentation and Distillation Purpose To prepare ethanol (alcohol) through fermentation and purify this using simple distillation.
