Multimesh Column Packing

Salient Features

• The high voidage of colpack allows free flow of both liquid and vapour through the packed column, resulting in low pressure drop per unit height of the packing.
• The high surface area of colpack permits an intimate contact between vapour and liquid, resulting in low values of HETP.
• The low bulk density of colpack result in decreasing the dead weight of the packed column. It also results in a lower shell thickness.
• The HETP (High Equivalent of a Theoretical Plate) of colpack is less than 15cm over the entire range of velocity.
• Due to the capillary effects of multifilament mesh of colpack, wall effect is almost completely eliminated.
• The flooding velocity of colpack is 2-2.5 times higher than those of conventional packings. this depending upon the requirement will reduce the column diameter or will increase the throughput.
