This design allows single or multiple counter-current flow and/or several applications in one unit (eg condensation, undercooling of residual gas and condensate by different media).
Another advantage of this design over conventional equipment is that it permits pure counter-current flow operation. This lets it make full use of the temperature differential. It also allows individual and optimum designs for each particular application. Resulting heat exchange area savings are up to about 40percent.
By providing optimised inlet flow, the design ensures almost uniform flow profiles across each tube bundle without dead spaces or areas exposed to undercurrents and turbulence. This is why these heat exchangers display excellent anti-fouling properties when used in media that naturally tend to cause fouling.
Operators with many years’ experience in this field such as Bayer, Wacker, Grillo, Degussa, Norsk
Hydro-Sweden and Vega do Sul-Brasilien will confirm these benefits.
Ease of handling is another special feature. Thanks to its small number of components, dismantling, for instance, can easily be done in just a few steps by the operator himself. Multi-tube bundle heat exchangers have been used for many years now in a wide variety of chemical processes as coolers, heaters, condensers, evaporators, falling-film evaporators and integral units for condensation with simultaneous residual gas cooling system (cold trap) or in pickling baths.
SGL Carbon process technology products also include block and plate heat exchangers, HCl synthesis units, columns, pumps, quenchers and safety discs in DIABON process equipment graphite, as well as pumps in exotic metals and PTFE-lined vessels and columns for the environmental protection, chemical, copper, steel, and pulp and paper industries.
