Major savings in production can be achieved by operating a process continuously. The BCT Loop Reactor has been adapted to continuous system and is being used increasingly due to its great potential to intensify the reaction. Significant shorter reaction time and the reduction of by-product formation is achieved. By cutting down operational costs up to 50 % such advantages can be realized not only in new plants but also by modifying existing ones.
The BCT Loop Reactor is well-known for its highest possible mass transfer and minimized reaction time. This makes it the ideal reactor system for continuous operation. Continuous operation results in a further reduction on utility and raw material consumption, on catalyst cost and it can even improve the product quality. In comparison to batch reactors a continuously operated BCT Loop Reactor can cut energy consumption and operational costs up to 50 %.
BCT engineers have developed other significant improvements to the BCT Loop Reactor to optimize continuous reactions even further.
