Two Dutch researchers have developed a method for managing so-called batch productions. During a batch production, substances react in a reactor vessel according to a certain recipe to produce an end product. After the reaction the reactor is emptied and a new reaction with the same recipe is started.
Chemist Eric van Sprang and chemical engineer Henk-Jan Ramaker have developed a control method that also takes the relationship between various process parameters into account. The current methods of process control monitor all of the parameters during the reaction, such as pressure and temperature, separately. As a result of this the control process costs a lot of time and not all of the process disruptions are clearly visible.
Batch control is important for safety, the environment and product quality. The quality of the product made in a batch process depends on the various parameters involved in the chemical reaction. However, these parameters are never the same for all batches.
