Applications related to Mixing, Mass Transfer and Reaction Rate

Heat Transfer and Process Scale-up
How Heat Transport in Agitated Vessels Affects Process Scale-up

Scaling-up a chemical process from lab to manufacturing gives useful results only with accurate heat transfer coefficients. Measuring the jacket and reactor temperature (during the release of a well-defined amount of heat) allows researchers to accurately compute the thermal resistance which is used to model the heat transfer and make critical predictions for reactors at larger scale. Reaction calorimetry is essential to determine parameters that impact the heat transfer and the heat transfer coefficients to develop models to maximize the bandwidth of a manufacturing plant. 

Chemical Synthesis
Screen and Optimize Catalysis, Hydrogenation, Polymer Synthesis and Other Reactive Chemical Syntheses

Chemists working in chemical synthesis discover and develop innovative chemical reactions and processes.

Temperature Effects Crystallization Size and Shape
Scaling-Up Agitation, Dosing, and Crystallization

Changing the scale or mixing conditions in a crystallizer can directly impact the kinetics of the crystallization process and the final crystal size. Heat and mass transfer effects are important to consider for cooling and antisolvent systems respectively, where temperature or concentration gradients can produce inhomogeneity in the prevailing level of supersaturation.

Process Safety
Thermal Hazard Analysis

Process Safety requires fundamental understanding of the thermal hazards of a reaction to ensure safe and efficient design and scale-up of synthesis reactions.

Chemical Process Safety
Determine the Safety of Chemical Processes Prior to Scale-up

How can I be sure that my chemical process is safe? It is critical to understand the risks inherent in moving a chemical process to a larger scale before manufacturing begins. The use of reaction calorimetry is an essential part of process development studies, providing detailed information about the rate of heat production. This allows researchers to optimize the temperature and dosing profiles to maximize process safety at all times, and reduce to a minimum the risks involved.
