Removing Liquids From Gas Streams

AZGAZ® Separator

Using patented technology, Merpro has developed AZGAZ® – a compact, lightweight, in-line gas/liquid separation unit. Specifically designed to remove liquid and solid particles from gas streams, AZGAZ® is ideal for free liquid knock out prior to compression.

How it works

AZGAZ® uses a combination of gravitational and centrifugal forces, together with its own tried and tested patented technology, to turn wet gas into dry gas.

Wet gas entering the unit is slowed down by the greater cross-sectional pipeline area inside, allowing larger liquid droplets to be effected by gravity and collect as liquid at the bottom of the vessel. Before it can progress any further, this liquid is caught by the first stage diffuser and drains into a collection pot.

The remaining liquid droplets, which are too small to settle under gravity, flow through the centre of the first diffuser in a fine mist. Next, they pass through our patented 2-stage fixed vane swirler, which forces the gas to spin. Here, enhanced ‘g’ forces and increased separation bring the smaller liquid droplets together and force them to the outer edge of the flow stream.

As they leave the swirler, these liquid droplets are caught radially, collected by the final diffuser and drained from the vessel.

Benefits at a glance

• Effective removal of liquid from gas streams – AZGAZ® removes 99.5% of all liquid droplets > 11 microns.
• Enables de-bottlenecking by increasing gas throughput from upstream equipment.
• Capable of operating over a wide range of inlet pressure and flow conditions.
• Compact, lightweight design minimises occupied deck space loading, requiring less substantial structural steelwork while freeing up available deck area.
• Low pressure drop makes a reduction in the size of downstream compression equipment possible.
• Flexible design – for high liquid loading levels (above 20% by volume), an additional diffuser section can be added to meet the increased load.
• Low maintenance – AZGAZ® is simple to operate and has no moving parts.

Proven track record

AZGAZ® separators have been successfully deployed by leading oil and gas companies in a variety of locations throughout the world.

Part of Merpro’s award-winning product range, AZGAZ® can be used in conjunction with other gas treatment packages, including gas scrubbers and gas compression units, to provide a complete process solution.
