REGULAR PACKING FOR HEAT EXCHANGERS Russian patent published in 2011 - IPC B01J19/32 

FIELD: process engineering.

SUBSTANCE: invention relates to designs of regular packing intended for heat-and-mass transfer in liquid-gas system and may be used in columns for absorption and rectification in gas, oil and chemical industries. Proposed packing is made up of reticulate two-layer zigzag-like strip made from net sleeve knitted in slurs from wire. Surface of net two-layer zigzag-like strip is arranged along the gas flow direction. Net wire diametre relates to main geometrical parametres of slurs as follows: where d is wire diametre, A is slur loop pitch equal to 7-9 mm, B is slut height equal to 6-8 mm, M is coefficient varying from 32.5 to 85.

EFFECT: reduced aerodynamic drag, higher efficiency.
