Demister pad sizing inputs
Record the process conditions needed to specify knitted-mesh mist eliminator pads and their support grids.
Characterise the gas and liquid
Give gas rate and density at operating temperature and pressure, liquid load and expected droplet-size range. The same pad density cannot be assumed suitable across all duties.
Check vessel fit
Specify vessel internal diameter, pad depth, manway opening and support-grid position. Large pads may need marked segments for installation.
Review operational effects
Fouling, foaming and corrosive condensate can drive material choice and cleaning interval. Confirm allowable pressure drop and required mist carryover with the equipment designer.
Specification checklist
| Parameter | Specification / example | Why it matters |
|---|---|---|
| Process | Gas/liquid properties and rates | Sizes the separation duty |
| Vessel | ID, manway and supports | Defines the supplied shape |
| Operation | Fouling and pressure limit | Defines maintenance plan |
Practical questions
What should I send when requesting demister pad sizing inputs?
Send the drawing or installed-part dimensions, the media or opening requirement, process conditions, quantity and the acceptance test you need.
Can a sample replace a drawing?
A physical sample is useful for fit and construction review. Dimensions, material grade and performance requirements still need written confirmation before production.
