Designing out blockages when handling process liquids that contain solids in suspension, or produce solid scaling. Nick Denbow reports
Rather than putting up with the downtime caused by scaling and blocking of heat exchangers, process operators should study the range of designs that allows easier passage of process liquids containing a heavy solids loading, while retaining good heat transfer efficiency.
The long-established spiral heat exchanger, which was originally developed for use in the paper industry, features two or four metal strips, onto which spacer studs are welded. The strips are wound onto a core to create two or four single-passage ...
