Segmented demister pads — Product view
A segmented demister divides the knitted separation layer into pieces that pass through the vessel manway. Each segment carries its own mesh and retaining grid, while match marks identify its place in the assembled pad. Segment width, diagonal and handling height define access through the manway; assembled vessel diameter is a separate dimension.
The layout sets support beams, grid overlaps, retaining clips and joints between adjacent mesh blocks. Continuous contact at those joints controls gas bypass. Installation follows the numbered layout, followed by inspection of joint contact, orientation, hold-downs and drainage space. Retrofit and large-vessel assemblies use the same complete pad geometry with a separately defined transport and installation split.
Lay out the pad as an installed assembly before setting segment widths. Each segment must pass the clear manway and handling route together with its grid or retaining frame. The full pad outline, segment transport envelope and support-beam locations are separate dimensions on the drawing.
Mark segment positions and the service face so the pad is reassembled in its intended order. Check grid-to-grid contacts and the perimeter against the vessel support. Preserve the mesh depth and drainage direction during lifting and packing. Keep dry mesh mass separate from the mass of grids, clamps and frames.
| Feature | Technical definition |
|---|---|
| Assembled pad | Vessel inside diameter, pad depth and support level |
| Individual segment | Outline, maximum diagonal, handling height and identification |
| Joints and restraints | Mesh contact, grid overlap, beams and retaining clips |
| Depth configurations | 100 /150 mm pad depth; grids dimensioned separately |
| Four-sector layout calculation | Ø1200 mm assembly in 4 sections; nominal quarter radius 600 mm |
| Component or stage | Function | Drawing or inspection definition |
|---|---|---|
| Installed outline | Defines the vessel fit | Pad diameter or length and width |
| Segment envelope | Defines entry through the manway | Clear opening, grid size and handling route |
| Support and joints | Carry and locate the segments | Beam positions, grid contacts and perimeter |
| Identification and drainage | Preserve the installed orientation | Segment marks, service face and drainage direction |
| Quantity | Value | Unit | Input or calculation |
|---|---|---|---|
| Assembled circle diameter | 1200 | mm | Defined circular layout input. |
| Equal sectors | 4 | sectors | Four equal quarter-circle sectors. |
| Sector radius | 600 | mm | 1200 / 2 = 600. |
| Maximum chord of an ideal quarter sector | 848.5 | mm | 600 × √2 = 848.5; grids and retaining frames have their own outer envelope. |
| Supply item | Order basis |
|---|---|
| Production lead time | 2–3 weeks after order and drawing confirmation. |
| Trial orders | Small trial quantities for fit and process evaluation. |
| Regular production orders | 50 pieces or US$3,000 per order. |
| Quotation basis | Material, finished dimensions, filter construction, connections and quantity. |
Individual sections pass through the manway and reassemble on the internal supports.
Matched segment edges form one continuous separation layer across the vessel.
