Graphite heat exchangers for aggressive media

OPEKS ENERGOSYSTEMA supplies special graphite heat exchangers for heat exchange processes with aggressive media, such as hydrochloric, sulfuric, nitric acids, and other inorganic and organic acids. Depending on the tasks set, plate, tubular, block heat exchangers can be used. So, for example, in the production of textile viscose, heating of a 20% sulfuric acid solution up to 60 C is used, a graphite plate heat exchanger can easily cope with this task. In the production of sulfurous salts, tubular graphite heat exchangers with low hydraulic resistance and a wide flow area have proven themselves well due to the use of larger diameter graphite pipes. The service life of graphite heat exchangers, depending on the technological process, ranges from 5 to 15 years, while the heat exchangers with lead surfaces used in the past had a service life of up to 1 year.
