Note 1: Vessel shall be suitable for removal of 95% of 200÷400 μm liquid particles.Mesh Pad Demister shall be suitable for removal of 99.9% of 10 μm liquid particles.

Note 2: Light Liquid Droplet Separation from Gas @ HHLLNote 3: For Operating Pressure P<0.1 barg and P>1 barg the 'KR' Demister Factor is extrapoleted.

See PRG.PR.VES.0001 Paragraph 4.1.3.Note 4: Overfilled is referred to Light Liquid OverflowNote 5: DeletedNote 6: All sizes are in mm, unless nozzle sizes are in inch.Note 7: Gravity Separation Lenght (L0) is the distance between TL and Demister.
