Designs

Horizontal Flow

Vertical flow

Selecting the right vane profile and the amount of stages for your demister (DH2100 and DH5000) for horizontal flow are key parameters for finding the right costs / benefit performance in your separation project. Together with certain peripherals such as integrated spray piping systems and nozzles for cleaning. We can design and offer the internals or the complete package with casing, vessel, piping and fittings as necessary.

Horizontal Flow

Gas - Liquid Vane Separators

Gas - Liquid Vane Separators

  • The vane type droplet separator or mist eliminator is used for applications with horizontal gas flows. The vane is suited for low to high gas velocities, eliminates very fine droplets and can be configured to most individual performance demands using various pitches. The benefits includes energy saving operations due to the very low pres sure loss and higher separation efficiency. The applications are in gas cooling processes, removal of condensed liquids, gas cleaning device, absorbers, exhaust air treatment plants, chemical plants, etc.

IDM Inlet Devices

  • This is an advanced type of inlet distributor that is commonly used for introducing gas/liquid mixtures into a vessel or a column. It removes liquid slugs and optimizes the downstream gas flow. The liquid removal capacity of the IDM is very high, with an efficiency of around 90 %. It is designed to handle very large liquid fractions and slugs, yet it has a low pressure drop and a very high resistance to fouling. The IDM not only removes the bulk of the liquid, it also evenly distributes the onward gas flow. The applications include Methanol plants, Olefin plants, Ammonia plants, Compressor suction drums and Knock-out drums.

Knock Out Drums

Knock Out Drums

  • typically used for liquid separation prior to compressor stations or for protecting equipment downstream like catalytic reactors, flares and others. The final configuration and internal parts of a knock out drum will depend on the type of industry and application as well as the expected amount of liquid to be separated

DS8000 Spin Vanes

  • The spin vane separators are an in-line installed equipment used for removing droplets for both horizontal and vertical gas flow. This equipment is specially been designed for separating larger amounts of coarse droplets at higher gas velocities from the gas stream. It is used for gas velocities up to 8 to 12 m/s. The benefits are elimination of excessive amount of liquids and lower pressure drop. Some of the applications include installation within piping systems between equipment, as a chimney fitting to prevent the discharge of condensate droplets, behind wet cleaning facilities involving solid and fibrous fractions or behind exhaust air scrubbers.

Vertical Flow

Demisters for columns, vertical vane separations as equipment internals, for pipe systems, ducts and stacks.

DV270

  • the most established and popular vane type separator for vertical flow and extremely low pressure drop for speed velocity range 1 to 5 m/sec. This separator is built by modular elements and can be installed via manhole; suitable for retrofit. This gas-liquid separator is available in round shape, rectangular shape as well as in tailor-made arrangement. It can be supplied together with housing and with integrated flushing / cleaning systems for sensitive applications.

DV880

  • a vane type separator for vertical flow and extremely low pressure drop for speed velocity range 1 to 5 m/sec. This gas-liquid separator is available in round shape, rectangular shape as well as in triangle shape. It can be supplied together with housing and in arrangement with flushing / cleaning systems for sensitive applications. A vertical flow replacement separator of this type allows easy installment and low maintenance.

DS8000 Spin Vanes

  • separator for vertical flow and extremely low pressure drop for speed velocity range 1 to 10 m/se c. This gas-liquid separator is available in round shape, it can be supplied with flushing / cleaning systems for sensitive applications. A first choice separator for high speed and for washing out particles. Available for pressure range up to 10 bar.

    Materials: plastic (PP, PVTF, etc.), carbon steel, stainless steel, duplex, titanium, inconel and others upon request.

Common Applications

Typical Process Applications

Distillation Towers

Liquid entrainment can cause performance problems and limit capacity in packed and tray distillation towers. At intermediate draw-off trays, entrainment from below reduces product purity and can allow non-volatile contaminants into the draw-off liquid. The overhead gas product can also be contaminated with liquid entrainment.

The entrainment is eliminated by a properly designed Mist Eliminator.

Knockout Drums

Designing knockout drums with Mist Eliminators reduce capital equipment costs and improve efficiency.

Steam Drums

Mist Eliminators reduce carryover of dissolved solids to obtain specified steam condensate purity levels.

Evaporators

Mist Eliminators reduce carryover of dissolved and un-dissolved solids to obtain specified steam condensate purity levels. This not only prevents product loss, but it also protects compressor internals in vapor recompression systems, provides boiler feed water quality condensate and prevents potential pollution problems.

Scrubbers

From clean gas scrubbers and process vents to fouling services, such as flue gas desulphurization systems or steel mill blast furnace exhausts, Mist Eliminators help improve efficiency and capacity.

Flue Gas Desulphurization

High capacity, low pressure drop Vane Type Mist Eliminators provide excellent resistance to fouling.

Refineries

Mist Eliminators in fractionators increase throughput capacity and allow deeper cuts for greater yields. In downstream crackers and reformers, mist eliminators prolong catalyst life by reducing carbon and metals in side draws.

Gas Absorption Systems

Systems using glycols, amines and other proprietary solvents removing contaminants from gas streams are optimized with Mist Eliminators to minimize losses of these expensive chemicals.

Petrochemical Plants

Mist Eliminators are used in the knock-out drums of the compressor trains to extend compressor run length and service life. They are also used in quench towers to prevent contamination and protect downstream equipment.

Munters offer a broad range of mass transfer products to help you attain a high-performance system. A tower that contains well matched components that optimize fractionation, absorption, stripping and extraction performance.
