30mm Vane Distance Chevron Plate Vane Pack Mist Eliminator 316L

316L 30mm Vane Distance Chevron Plate Mist Eliminator

1. Chevron Plate Mist Eliminator Project flue gas parameters

The parameters of flue gas collected by closed coke storage system of delayed coking unit are shown in Table 1; After dust removal and desulfurization, it is discharged from the top of the flue gas tower, and the parameters of the net flue gas are shown in Table 2.

2. Our experience in chevron plate mist eliminators

I have a customer from South East Asia, who is in the vessel repair and service business. Early this year Mr. K enquired to us for a kind of vane plate mist eliminator to be used in ventilation system of vessels. It had limited space for the vessel and nominated gas flow direction, which was different from our normal intallation way. I listened to Mr. K carefully and made the draft drawing below for his checking. I took both the gas flow direction and space into consideration. Meanwhile I checked with our workers beforehand to see if they could realize my design with our raw material. After friendly communication, everything was settled and the order went into production soon.

Hualai vane plate mist eliminator allows inlet air to turn and pass between the profiles with minimum restriction. Drops impact the profile surface where they are collected and drained.

3. When to use chevron plate mist eliminator instead of mesh pad?

4. Chevron plate mist eliminator structure

The vane types are the Chevron type of mist eliminators which consist of a set of specially designed vanes with a well defined geometry, with closely spaced corrugated plates. They are very usual and useful internals for liquid separation from gas. These types according to design and shape can remove the droplets more than 8 microns.

Hualai has produced a range of mist eliminators for critical applications in the oil and gas sector, Standard Material of vane type mist eliminator is polypropylene & stainless steel.

5. Hualai capacity in chevron plate mist eliminator manufacturing:

Basically, we can produce and supply two vane height types, 170mm and 235mm, in both PP and stainless steel material. No problem for any shape and size.

Vane type eliminator is mainly used for flue gas desulfurization and separation of mist droplets in tail gas. It has the advantages of simple structure, high capture efficiency for medium size and large size mist droplets, low pressure drop, easy flushing, open structure, easy maintenance and low cost.

Removal of very small droplets can be achieved using a two stage mist eliminator by fitting a mesh pad to the upstream face of the unit to coalesce droplets as small as 4 to 5 microns into droplets in the size range which are easily removed by the vane separator.
