Vane Packs Demisting Devices

The vanes in vane packs can be either of the no-pocket (straight), single-pocket or double-pocket type.

Of the three vane types the straight vane has the lowest sensitivity to fouling, but has also the lowest gas handling capacity.

The double-pocket vane type has the highest sensitivity to fouling, but its efficiency above λmax (where liquid re-entrainment starts) deteriorates to a lesser degree than with the other types because the separated liquid is better shielded from the gas flow. ).

In horizontally flowed-through vane packs the single- or double-pocket types are normally used. Horizontally flowed-through vane packs are typically used in vertical vane-type demister vessels.

Vertically flowed-through vane packs are equipped with either straight or double-pocket vanes. In this application the low efficiency of the vane pack is less of a problem since the vane pack functions normally as a coalescer for the downstream swirldeck. Howver, the vanepack can not provide the same turndown as a coalescing mistmat.

A vertically flowed-through vane pack with double-pocket vanes is only recommended if the service is clean. Since it has a higher gas handling capacity than mistmats and requires little height (at most about 0.20 m) it is a suitable retrofitting device to upgrade undersized wiremesh demisters by installing it downstream of (i.e. above) the mistmat.
