In certain applications the use of Koch-Glitsch Grid® should be considered. Koch-Glitsch Grid is fabricated from panels 15″ wide, 60″ long and 2 1/8 ” deep. They are placed in the column in a predetermined orientation. Grid has been used in the pumparound zones of crude columns and FCC fractionators. Grid and Pall type rings are used in GRC beds (Grid/ring combination) in vacuum columns preparing feedstock for FCC fractionators. Grid has about 50-75% more capacity than trays and may have an application in revamp projects.
