GRAPHITE HEAT EXCHANGER-BLOCK TYPE

Block Graphite Heat Exchangers - YK series

The main reason for employing block graphite heat exchangers is their great flexibility. Block Graphite Heat Exchangers can be used for nearly all heat transfer and mass transfer process involving corrosive media. We offer system-based, multi kind of block graphite heat exchangers with convincing advantages:

- Graphite high thermal efficiency

- High resistance to thermal shock

- Rapid replacement of damaged graphite blocks due to compact modular design
- Easy maintenance (easy cleaning and graphite block replacement) allowing simple dismantling and assembly
- Suitability for corrosive media on both process and service sides, depending on design

Structure Characteristic of Block Graphite Heat Exchangers:
Heat transfer takes place in solid graphite blocks with a crosswise arrangement of drilled flow passages for the process and service side. The size of the graphite blocks and the passage diameters vary according to the application and type of graphite chemical equipment concerned. Several graphite blocks are assembled to form a graphite column, which provides the required heat transfer area in a single unit. The graphite blocks are arranged in such a way that the product passages aligns with one another. As a result, corrosive medium flows through the axial passages. The service medium in the steel or graphite shell space passes through the horizontal passages. A flexible baffle cage produces forced flow deflection on the service side.

Application of Block Graphite Heat Exchangers:
Since block graphite heat exchangers are compact and very adaptable, Block graphite heat exchangers are mainly used as:
- Overhead graphite condensers and graphite coolers, e.g. on absorption and separation columns
- Steel pickling line heaters
- Reactor coolers
- Graphite condensers and graphite coolers on agitators and reaction vessels
- Circulation coolers for quenchers
- Preheater for evaporators

- Reboiler
