Liquid distributor drip-point density should be defined using the active area and approved outlet layout. Total outlet count alone is not sufficient; spacing, wall coverage, flow per outlet, turndown, and fouling risk must also be considered.

Demister procurement should clearly define lower support, upper hold-down, material, sectional arrangement, attachment interface, and supplier scope. Unclear support responsibility can create installation delays even when the mesh itself is correct.

Vane mist eliminator procurement should control blade spacing, profile, drainage features, thickness, flow orientation, and module dimensions. Significant geometry changes should require technical approval.

A wire mesh demister specification should define wire diameter, mesh density with clear units, pad thickness, material, segmentation, and support scope. These parameters should be controlled together rather than altered independently.

Wire-mesh structured packing should be specified using material, wire size, mesh construction, corrugation geometry, element dimensions, and approved technical data. Packaging should also protect the relatively delicate structure from compression and distortion.
