Heat exchangers innovative designs

Different heat transfer applications require different types of hardware and different configurations of heat transfer equipment. The attempt to match the lieat transfer hardware to the heat transfer requirements within the specified constraints has resulted in numerous types of innovative heat exchanger designs. 

The Chart-flo heat exchanger and its stablemates in the heat exchanger reactor field (see Chapter 5) are the latest truly innovative designs to enter the CHF marketplace. Produced by Chart Energy and Chemicals, the Chart-flo unit extends the option... 

Figures IV-15 and IV-16 show the innovative check valve designed and patented for the MARS sees and the SCCS primary heat exchanger.

Caution Whereas all the designs we include have found some successful applications, the key to success here is to find the right application, and as ever we will add the further cautionary note that the best approach is most often to copy a successful application or design rather than to innovate. Therefore, dear reader, please use caution when attempting to use any iimovative designs or applications where they have not already been used with success. Ask around if you have an idea to improve heat exchange on your process unit see if you can find someone else who already had success with the same approach. 

The Mont Cerris Process was operated at a pressure in the range 100-120 bar, and at temperatures below 450°C because the catalyst was rtrrstable at higher temperatures. Several of these low-pressure plants were built before 1930. Since then Uhde has designed many corrventiorral ammonia plants and the associated ammonia converters (Figure 10.1). One of his innovations was the use of tube-cooled converters to improve heat exchange and to preheat inlet gas to maintain a more uniform temperature through the catalyst. ... 

The success of membrane reactors for hydrogen production is basically associated with (i) the advances in membrane production methods and (ii) the design of innovative reactor concepts, which allow the integration of separation and energy exchange, the reduction of mass and heat transfer resistances and simplification of the housing of the membranes.
