Reaction Calorimetry Capability Added to Parr Reactors

Parr 4540, 1.2 L Reactor, with H2 and liquid feeds, equipped for Power Compensation CalorimetryParr has integrated the principles and practice of reaction calorimetry into our reactor systems.

Reaction calorimetry is often used for studying chemical reaction rates and the thermal properties of systems. In chemical processing industries, this technique is used for understanding and mitigating hazards from the scale-up of reactions developed in the lab to industrial-scale reactors. As a reaction is scaled from lab to plant, scalability problems may emerge for various reasons. Issues are often attributable to a lack of understanding of the process chemistry, the inability to remove heat or changes in mixing performance during scale-up. Reaction calorimetry provides this additional level of process understanding.

The principal output from experiments performed in a reaction calorimeter is the heat production rate associated with the processes occurring inside the reactor. The heat production profile becomes the basis for the determination of a number of important operational parameters.

Large Volume Stirred Reactor Systems

Parr's new 50 L & 100 L high pressure stirred reactors are ideally suited for scale up or pilot work. The geometry, features, and operation are very similar to that of smaller Parr reactors, but with a volume intermediate between lab-scale and traditional production scale stirred reactors. Custom options are available.

Tilt-to-Empty Feature

Emptying large high pressure reactors typically requires a bottom drain valve, which in some applications is undesirable. For researchers working with abrasive slurries, biomass particles or other materials incompatible with bottom drain valves Parr has developed a "Tilt-to-Empty" feature.
