Dave Butterworth became interested in multistream exchangers after becoming Chairman and General Secretary of the Aluminium Plate-fin Heat Exchanger Manufacturers' Association (ALPEMA). He gave a Forum presentation on 20 April at which he explained the some of the intricacies in the construction of such equipment and the benefits that they can have.
Multistream exchangers can be of two types
-
Those in which, at any point in the exchanger, the heat transfer is only between one hot stream and one cold stream. We should call these 'multi-two-stream' exchangers
-
Those in which at places in the exchanger, heat can be exchanged between a number of hot and cold streams.
Dave concentrated on the latter type with the aim of the talk of introducing those familiar with two-stream exchangers to the exciting feature of multistream exchangers.
