Wright-Austin R Gas Liquid Separators

Receiver Style Separators for High Liquid Loads

Cutaway View of a Receiver (R) Gas/Liquid Separator

Wright-Austin R style air/liquid separators are the most complex centrifugal separator design offered, designed specifically to handle liquid "slugs" or heavy liquid loads.  The creation of a powerful vortex and centrifugal separation is the same as the other designs; where the Receiver (R) style differs is its large reservoir and dual vortex chamber design enables it to handle a higher liquid load and minimizes the physical diameter and length of the vessel.  Whereas a Type T separator has a liquid removal capacity equivalent to 40% of its maximum rated capacity, Type R separators have a 90% liquid removal capacity.

The entrained liquid within the gas entering Type R separators impinges upon an angled surface and its angle of entry is also downwards at an angle.  Coalescing of droplets from impingement on the plate and vessel walls collect at the bottom of the separator and drain port.

The exit path is located at the top of the vessel, thus the gas passes through an angled separation element and only the finer droplets pass through it without impinging on the exterior separation element.  The angled entrance into the separation chamber creates a powerful vortex; the resulting centrifugal force propels droplets and particles larger than 10 microns outwards toward the lower section of the separation element where they coalesce to a drain pipe having its exit near the main separator drain port.  The exit nozzle protrudes into the low velocity section of the separation vortex where only droplets smaller than 10 microns can pass, so the resulting dry, clean gas flows upwards and exits through the outlet of the separator.  The separation is accomplished without complex baffles, deflectors and other structures that obstruct the flow-stream and this results in very low pressure drops compared to other designs.  Type R separators remove entrained droplets larger than 10 microns with 99% efficiency, having no internal moving or serviceable components; they are a fully welded pressure vessel requiring no maintenance for the service lifetime.  R style gas/liquid separators are fabricated from carbon steel, 304SS, 316SS and can also be fabricated from exotic alloys as needed.  An ASME code stamp and CRN can also be provided.
