Technology
The KnitMesh V-MISTER™ provides high performance wherever liquid entrainment must be removed from a vertically flowing gas stream.
Demisting pads with KnitMesh V-MISTER™ technology employ the mechanism of a Von Karman Roll around a bluff body (see figure on top) to obtain high vapor and liquid handling capacity. Here, a vortex develops in a low pressure zone downstream of the channel that has been attached to the bottom of the mesh pad.
Collected droplets deposit in the trough and form a flowing liquid stream there. Contrast this with the standard mesh pad (see figure KnitMesh V-MISTER) where a two phase ‘fluidized’ zone of gas and liquid develops in the bottom third to half of the pad, and from which large coalesced droplets must ultimately drain counter-current to the ascending stream.
The high capacity channels of the KnitMesh V-MISTER™ shield the collected liquid and then drain it in steady streams, from two sides of the mist eliminator, at the tower periphery where gas velocity is so low that re-entrainment almost never occurs.
