Simular | Process Development Reaction Calorimeter
Thermal properties of the desired reaction (1)
The Simular measures the energy evolved in the reaction. Subsequently, this enables you to calculate the plant cooling capacity required to keep the reaction isothermal (Tp).
Thermal runaway of the reaction (2)
In the event of plant failure, it is critical to understand the maximum temperature the main reaction will reach during any subsequent thermal runaway.
The Simular enables the Maximum Temperature of Synthesis Reaction (MTSR) to be calculated from the data of the reaction. Multiple reaction conditions can also be screened to help understand the kinetics of the reaction. From this, it can be assessed whether there will be sufficient time and emergency cooling capacity to deal with the temperature increase.
Minimizing the risk
Hazard assessments may highlight insufficient plant emergency capacity to avert the risk of thermal runaway. The Simular can be used to explore and design safer reaction conditions, thereby facilitating the optimization of safe operations and minimizing process risk.
