May 2016 – Coflore ACR Eliminates Need for Multiple Heat Transfer Zones

The Coflore ACR is a flow reactor that decouples mixing and plug flow from residence time. Controlling the temperature of an nth order reaction in flow can be achieved with multiple heat transfer zones operating at different temperatures. The disadvantage of this set up is that it requires multiple heater-chillers which adds cost and complexity. A simpler solution is to use a single heat transfer zone with a tuned ‘approach temperature’ (figure 1).

 

Traditional heat transfer jackets do not function effectively at the very low HTF flow rates required for this. The new ACR reactor uses actively mixed heat transfer cells which decouples heat transfer performance from HTF flow (figure 2). This allows precise tuning of the jacket temperature with a single supply of heat transfer fluid.

 

A spread sheet solver is provided with each reactor block to save time for set up.
