Filters & Seperators

Filters & Seperators

Mechasol has the capability to design and supply​​ gas filtering equipment with different process technologies:

  • Slug catcher / KO drums (Gravity separation: in absence of turbulence, under the effect of gravity, the different phases of a mixed stream, after a certain time, decant and form interface levels​​ between phases)

  • Gas / liquid separators (Impingement separation: vane or demister type, when a drop of liquid hits an obstacle, it tends to adhere to it and to coalesce with other droplets that hit the same obstacle)

  • Separators (Centrifugation separation:​​ mini cyclonic separation is a method of removing particulates from gas through vortex separation. Rotational effects and gravity are used to separate mixtures of solids and fluids)

  • Process liquid filters / coalesce (Coalescing separation: small droplets such as lubricating oil, process liquids and other fluids with a low interfacial surface tension liquids should be removed from gas through coalescing separation - fiberglass cartridge)

Mechasol directly manages the entire value chain: equipment (including QOC) are designed and manufactured internally with big advantages in terms of flexibility and quality.

 

Fılter Separators

Gas filtrating separator is an important equipment in gas transmission and distribution system. During the gas transmission and​​ distribution, flowmeter, regulator,and valves require protection against the damage potential of solid impurities and liquid impurities. That is, high-precision filtrating separator must be installed in front of the critical equipments

 

Mechasol's range of​​ filter separators is intended for those applications where a high efficiency removal of solids and liquid particles is required, regardless of their size. The use of these separators is the best solution to remove very fine mists or aerosols from the gas​​ flow. Other applications include the removal of lubricating oil from process gas, entrainments in natural gas lines upstream compressor stations, reducing and metering stations, etc.

Principle of operation

In filter separators, removal of solid and liquid particles takes place gradually.
At vessel inlet, larger particles are removed by gravitational effect due to the gas velocity decreasing and by impingement on inner surfaces.
Filter elements entrap the smaller solid particles, while liquid droplets coalesce to be removed in the following stage consisting of a vane unit. The contaminant is collected either in a separate reservoir connected to the filter separator or in the same vessel out of the gas flow.

Horızontal Coalescıng Separator

Mechasol Horizontal double barrel and/or Vertical filter​​ separators are designed to provide efficient liquid/solid removal and high gas capacities. The coalescer filter section removes bulk liquid and solid particles and also coalesces fine liquid droplets into larger ones. These larger droplets are then removed​​ in the second Double Pocket (DP) Vane] section. Mechasol utilizes high capacity DP Vanes to increase the separator’s throughput and thus minimize the separator diameter.

The double barrel configuration allows you to maximize the gas flow in the upper barrel without re-entrainment while the liquid drops into the lower barrel. Mechasol offers standard coalescing filters that can be replaced periodically or designs that can be cleaned and reused.

The horızontal coalescıng separator​​ provıdes effectıve coalescıng of aerosols streams when placed ın front of:

  • Compressors to remove water/oil mist and dust which could cause damage to the valves and cylinders

  • Desiccant dehydrators to prevent lube oil mist or other liquid contaminant from​​ entering the absorbent bed causing
    degradation loss or effectiveness of the desiccant or treating media.

  • Glycol dehydrators to remove compressor lube oil mist, from the gas stream, to prevent contamination or foaming of
    the glycol fluid.

The horızontal coalescıng separator provıdes effectıve coalescıng of aerosols streams when placed after:

  • Compressors to remove lubricating oil mist in the discharge stream

  • Contactors to remove glycol or amine carryover downstream

 

Vertıcal Coalescıng Separator

The removal of​​ entrained liquid aerosols, such ascompressor lube oils, trace hydrocarbons, and water mist, from natural gas
streams is necessary for the protection of downstream equipment. Efficient removal of these contaminants, by use of an effective
coalescing separator and media combination can prevent costly problems and downtime with downstream equipment, such as
compressors, membranes, instrument valves, piping, etc.

Features of a vertıcal confıguratıon:

  • Utilizes gravity to remove liquid.

  • Only the lower portion of​​ the element is saturated with liquid.

  • Ability to allow more flow-through in a given house size.

  • Ability to down-size expensive hardware and maintain flow rates

Dry Gas Filters​​ 

 

These filters have been proved to be the best solution in those applications​​ where the size of particles to be removed is too small to allow the use of common separators.​​ Mechasol's dry gas filters can remove solid particles from a gas stream in every working condition, by using a number of suitable filter elements . These filter elements are chosen according to the requested grade of filtration efficiency and pressure drop , besides other factors as type and quantity of entrainments , maintenance space , etc .

Principle of operation

Filtration of solids:​​ as the gas gets into the​​ filter, the velocity decreases and the heavy entrainments drop out of the gas stream. The gas then raises and flows through the filter elements. Here the micronic particles are trapped in the fibres and retained; clean gas then flows through the inner perforated metal liner (core) to the filter outlet.

Filtration of liquids:​​ for this application the real task of the filter elements is not to filter the liquids but to cause a coalescence effect. The liquid entrainments, in the form of fogs, lay on the​​ fibres of the cartridge generating larger and heavier droplets which will be removed by gravity at the outlet of the cartridge itself.

Vane Separators

Vane separators are the best solution to the problem of separation of liquid particles from gas or mist, as they offer high efficiency, low pressure drop, and low maintenance cost. The​​ vane unit is the heart of every type of separator shown in this catalogue: consisting by various vanes, according to the different operating conditions, it can be manufactured in carbon steel, stainless steel, aluminium, etc., in order to meet customer's​​ specifications

Principle of operation

The tipical vane type separator: the gas gets into the vessel and passes through the vane unit, splitting into many fluid ribbons, subject to sudden changes of direction, which cause a semi-turbulence, with consequent rolling of liquid entrainments against the walls of the vanes. Drops, enter into the the vane pockets and fall by gravity into the lower part of the vessel, where they are collected and drained.

Multitube separators​​ 

Multitube separators are the​​ most suitable answer to eliminate liquid and dry gas impurities. They are used both at wellhead and at inlet to compression station, in distribution systems and in many other industrial processes.​​ 

Advantages:

- high separation efficiency, even at the presence of wide flow rate variations, which makes them suitable to be installed on plants to be extended in the future.

- constant pressure drop regardless of contaminant loading and servicing.

-low maintenance requiring only occasional blowdown of collected material .

Principle of operation

The separator element consists of multiple small diameter cyclone tubes assembled in tube bundles. The dirty gas enters through ports L, causing a swirling motion, which throws dry and liquid entrainments against wall​​ C of the cyclone tube: clean gas changes direction at the vortex and rises out through​​ outlet tube T. Impurities, being heavier, fall down through hole F into the proper storage area.
