How do Koch-Glitsch packed column design procedures dilfer from those 01 other manufacturers?
For the past 25 years, a widely known packing manufacturer has designed columns using the Generalized Pressure Drop Correlation method. This method assumes all packings behave sufficiently alike that they may be compared on the basis of a pressure drop value and not percent of flood or capacity. Recently the manufacturer has published articles proclaiming the need to improve the design methods previously used. The “new” method employs the use of “C” factor, which is the method Koch-Glitsch has always used. The basic difference is that the Koch-Glitsch method has always designed on the basis of maximum capacity and not a pressure drop rule of thumb.
