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
Producing Quality, Economically-Viable Molecules

Chemical synthesis occurs when two or more molecules are combined to form a product molecule that possesses specific properties. There are numerous examples of chemical synthesis that results in important products for the pharmaceutical, polymer, fine and bulk chemical industries. To achieve optimized yield, quality, safety and cost metrics, chemical synthesis requires a thorough understanding of the kinetics and thermodynamics of the underlying chemistry, as well as carefully controlled and monitored reaction conditions.

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.

Bezpečnost chemických procesů
Prevence ztráty kontroly nad chemickým procesem

Cílem bezpečnosti chemických procesů je předcházet nehodám a mimořádným událostem ve velkovýrobě chemických látek a léčiv. Zabývá se prevencí nežádoucího uvolnění potenciálně nebezpečných materiálů a energie v průběhu chemické reakce do okolí v případě, že se chemická reakce vymkne kontrole.
