Micro heat transfer module

The micro heat transfer module (Figure 3.15) comprises a stack of micro structured platelets which are irreversibely bonded [29, 30]. The module is heated by external sources, e.g. by placing it in an oven or by resistance heating. The single parallel flows are all guided in the same direction on the different levels provided by the platelets. Before and after, distribution and collection zones are found, connected to inlet and outlet connectors.

Thermally induced radical chlorination of alkanes using a hybrid system consisting of two micro heat-transfer modules and a conventional tube reactor has been reported [1, 5]. The exact nature of the alkanes and products, however, has not been disclosed for confidentiality reasons. 

This paper describes work on equipment and instrumentation aimed at a computer-assisted lab-scale resin prep, facility. The approach has been to focus on hardware modules which could be developed and used incrementally on route to system integration. Thus, a primary split of process parameters was made into heat transfer and temperature control, and mass transfer and agitation. In the first of these the paper reports work on a range of temperature measurement, indicators and control units. On the mass transfer side most attention has been on liquid delivery systems with a little work on stirrer drives. Following a general analysis of different pump types the paper describes a programmable micro-computer multi-pump unit and gives results of its use.
