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.

Large structured packing should be segmented according to actual manway access, handling limits, and installation sequence. Segment arrangement, marking, and packaging should be approved before manufacturing.

Structured packing RFQs should define total bed height, element height, layer count, segment arrangement, and installation orientation. Clear marking and layer identification can prevent site installation errors.
