Overview
Highly Configurable & Flexible System
The Simular Process Development Reaction Calorimeter is a highly configurable and flexible system, designed as part of the H.E.L product family for process safety and chemical synthesis, featuring dual reactor options. Its unique capabilities as a calorimeter and an automated jacketed reactor allow for exceptional versatility in various applications, including adiabatic calorimetry, autocatalysis, and batch and semi-batch reactors.
Optimize Process Conditions
Leveraging the derived thermodynamic and kinetic information of the reaction, the system aims to optimize process conditions, achieving the dual goals of maximizing product yield while minimizing safety hazards. It enables efficient and effective adjustments to key operating parameters by precisely monitoring and controlling the heat flow.
Determine Safer Reaction Conditions
Determining the safer reaction conditions is crucial to ensuring safety during scale-up operations. The system facilitates this by calculating the plant cooling capacity required for maintaining isothermal conditions (Tp) and accurately predicting the maximum temperature the main reaction may reach during a thermal runaway. These calculations are vital in determining the emergency cooling capacity needed for robust scale-up.
Calibration-Free Power Compensation Calorimetry
The Simular Process, Development Reaction Calorimeter, supports both classic heat flow calorimetry and advanced calibration-free power compensation calorimetry. This advanced feature allows users to choose the most appropriate method for their specific reaction requirements, ensuring accurate and reliable measurements for precise process control and optimization.
Applications
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.

My experience with H.E.L dates since 2005. During these years H.E.L was the provider of the most important lab equipment with the help of which I developed many different API pharmaceutical processes in the companies l worked for including Merck, Pfizer, and Theravance. The versatility of the automated lab reactors (AutoLAB), the ease of use of and the accuracy of the TSu and Simular systems, as well as the flexibility of the PolyBLOCK made my work much easier and accurate. I would like to mention the great relationship I established with the service engineers and the sales people at H.E.L. With their help I was able to customize the software and the hardware of the equipment to our specific needs. This readiness to accommodate each customer’s specific needs gives H.E.L the edge over their competitors and makes them the preferred vendor for pharmaceutical lab equipment.
