Double stage filters separators

The vane pack separator allows to have a high efficiency in the separation of liquid particles inside a gas stream.

Depending on customers’ needs, the materials used for the realization can be different: carbon steel, stainless steel and special austenitic ferritic steels such as Duplex, Super Duplex, Nickel alloys and Titanium Gr. 2, considering also the conditions in which the filters operate.
This type of filters is the best solution to the problem of the separation of liquid particles from gases or vapours, combining their high efficiency with low pressure drop, a low initial investment and minimum maintenance over time.
The gas, after entering the tank and passing through the vane pack, is divided into several sections in which it is forced to follow trajectories with numerous changes of direction, thus causing the liquid droplets to roll over the walls of the reeds, agglomerating into larger drops and precipitating for gravity.

In this way, the drops fall into the bottom of the tank, where they are collected and drained.
The separation efficiency of these devices is equal to 99.5% for the drops with 8-10 microns or greater in diameter.
Installation can be vertical or horizontal: this arrangement works well if the gas contains significant quantities of liquid.

Typically, this type of filters is used at the entrance of the installations for the treatment of fuel gas.
We can design this type of filter for many application: removal of solid particles, removal of liquid particles (coalescent filters).
The filter elements can be realized in all type of metallic and plastic materials, polyester, needlefelt and glass microfiber.

Type of gas: Industrial, Oxygen, Hydrogen, Nitrogen, Air, Natural gas.
This type of filters is used for scrubber plans and metering skids for natural gas purification before turbine.
They are often installed before a double stage filter.
