Simular | Process Development Reaction Calorimeter
The Simular is a reaction calorimeter that is used within process development to investigate the thermal properties of a chemical reaction under the proposed operating conditions. The Simular allows for the optimization of process conditions for maximum product yield and minimal safety hazards, based on the derived thermodynamic and kinetic information of the reaction.
The Simular enables the determination of the plant cooling capacity required to keep a reaction isothermal (Tp), and the calculation of the maximum temperature the main reaction will reach in the event of a thermal runaway. The parameter known as the Maximum Temperature of Synthesis Reaction (MTSR) is a critical value in determining whether the emergency cooling capacity in a plant is capable of dealing with an increase in temperature. The Simular can be used to determine safer reaction conditions.
The Simular supports both the classical heat flow calorimetry method, and the quicker, more efficient, calibration-free power compensation calorimetry method, allowing selection of the most appropriate method for the scenario that is of interest.

Reaction Calorimetry
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.
