Solutions for the chemical industry

Sublimation / Desublimation Integrated Process

The LIST technology enables continuous reactions without the use of solvents, handling of materials that are difficult to dry, sublimation/desublimation processes, and large-capacity integrated processes. For example, it achieves high-efficiency processing in the production of cyanuric acid through the thermal decomposition of urea and in the evaporation and drying process of TDI. In particular, by utilizing continuous kneaders and vacuum processing technology, it allows for the combined processing of mixing, reacting, evaporating, and drying, leading to cost reduction and improved production efficiency. The safe and sustainable process design can meet the diverse needs of the chemical industry. LIST Solutions for the Chemical Industry: - Continuous chemical reactions without the use of solvents *Process Features: The temperature of the reaction mass is strictly controlled, minimizing the risk of product degradation. There is no need for recovery and purification as solvents are not used. *Advantages of LIST's single-axis continuous kneader/reactor: - Minimizes material handling through a continuous and automated process. - Combines the mixing and reaction of reactants in a single device. *Continuous vacuum sublimation/desublimation process for solid materials Economic Benefits: Complete recovery allows for significant cost reductions compared to conventional simple evaporation processes. A single unit can process up to 6,000 tons of free TDI annually.
