Question
Are there any alternatives to scraping a shell and tube if a capacity increase will make the pressure drop across the exchanger too large?
Answers
When an increase in capacity will cause excessive pressure drop, you may not have to junk the heat exchangers. A relatively inexpensive alteration is to reduce the number of tube passes. Other possibilities are arranging the exchangers in parallel or using lowfins or other special tubing. Source: Gulley Computer Associates   Your Comment
