CRE 46 LAMINAR FLOW REACTOR

DESCRIPTION

 

Reactors with laminar flow are tubular reactors and are operated continuously. They allow analyses of chemical reactions under defined flow conditions with the characteristic retention time distribution.

It is part of a device series that enables experiments with different reactor types. In conjunction with the supply unit for chemical reactor, it is possible to examine the function and behaviour of a reactor with laminar flow in continuous operation.

The supply unit for chemical reactor has a heating water circuit as well as all necessary connections, pumps, tanks for reactants and a product tank. In combination with Water Chiller and the supply unit for chemical reactor it is also possible to cool the reactors.

The supply unit has a heating water circuit as well as all necessary connections, pumps, tanks for reactants and a product tank. In combination with Water Chiller and the supply unit for chemical reactors it is also possible to cool the reactors.

It is mounted onto the supply unit and held by two pins in position. Quick-release couplings enable easy connection of the reactor to the supply unit.

In continuous operation, two pumps on the supply unit deliver the reactants into the reactor. Due to the dimensions and possible volume flows laminar flow is formed. The product is formed by reaction of the reactants. The mixture of product and unconverted reactants leaves the reactor after a specific retention time through the upper end.

The mixture is transported into a tank of the supply unit via an additional peristaltic pump.

The retention time of the reactants in the reactor is adjusted via the speed of the pumps on the supply unit.

The conversion in the laminar flow reactor or is determined by measuring the conductivity. A combined conductivity/temperature sensor is included in supply unit for chemical reactors. Conductivity and temperature are digitally displayed on the switch cabinet of the supply unit. In addition, the measured values can be captured and processed with data acquisition software.
