500mm gas liquid separator for test with plain mesh and crimped
mesh
Gas velocity of gas liquid separator:
Max gas velocity:uf=K[(ρL-ρG)/ρG]1/2 m/s
ρL——density of liquid drop Kg/m3
ρG——density of gas before demister Kg/m3
K——Gas-liquid separate mesh constant
Recommended operation gas velocity:ug=0.50uf---0.80uf m/s
How does a liquid gas separator / demister work?
(1)A vapor stream carrying entrained liquid droplets passes through
a demister pad. The vapor moves freely through the knitted mesh.
(2)The inertia of the droplets causes them to contact the wire
surfaces and coalesce.
(3)The large, coalesced droplets formed in the mesh ultimately
drain and drop to the vessel bottom.

Please pay attention to the Unit when refering to this sheet.
Wire mesh gas liquid separator, which are used in removing droplets entrained in flow gas, is
constructed from knitted wire mesh with a cellular structure. The
knit mesh are made into a mesh pad with determinate thickness and
diameter, through which the two phases liquid-gas or liquid-vapor
are disengaged.
From the statistic data obtained both in laboratory tests and
industrial applications, it shows that the proper designed mesh pad
demister allows a separation of liquids carried by gas with
efficiency reaching 99.9%.
