In the coal chemical production process, there are a large number of heating and cooling processes, using a large number of heat exchange equipment, coal chemical plate heat exchanger is widely used, what are the special features in its selection process?

Plate heat exchanger in a long time, the proportion of water-water heat exchange is very large, the general medium is nothing corrosive, do not need to make the rubber strip dissolution, aging and other phenomena. But the coal chemical plate heat exchanger using the media, in addition to water, most of them are poor, rich liquid and ammonia and other kinds of chemical media, easy to make the rubber strip swelling, aging, so its selection process to pay attention to whether the rubber strip can be suitable for its media, the choice of rubber strip is critical.
