12/29/2010 12:49 AM

Hi everybody

When a stag of plate fin heat exchanger is plugged by oil or particles, according to ALPEMA standard, one way for degreasing the stage is use of gas bubbling method in which, bubbles generated in liquid provide required energy for dislodge particles and oil from the stage, Any help would be appreciated to finding details and information about this regard

Best regards

Depending upon MOC of tubes and fins and type of particles stick to fins, detergent concentration and the bubbling pressure shall be set. You may have to bubble at more points at a time to clean the bundle throughly. This is time consuming but safe method of cleaning. But after cleaning, never forget to hydrotest your tube bundle.
