Scrubber Design and Installation Req...

1. Liquids and particulates are incompressible and can negatively impact compressor performance

and reliability. Each stage of compression requires an upstream scrubber or some other device to

remove both free and entrained liquids from the gas. The scrubber requires a high liquid level

protection system and an automated drain system. In case of abrasive particle carry-over, contact

an experienced filtration system manufacturer for assistance. A debris sample may be

required to determine its properties, origin, and appropriate filtering techniques.

NOTE: Non-intercooled, dry gas stages of compression may not require liquid separation,

but provisions must be made to remove lubricating oil, if applicable.

2. Design and construct scrubbers in accordance with good engineering practice and industry standards

for two-phase separators and pressure vessels. ISO-13631 provides scrubber specifications.

Provide full diameter skirts with a thickness equal to or greater than the vessel wall

thickness (minimum 1/2 inch (13 mm)).

3. Support scrubbers with full-depth structural members.

4. Position all scrubber attachments such as relief valves, sight glasses, instrumentation, drain

lines, and tubing close to the scrubber and support as required. Bullseye style sight glasses are

recommended.

5. Ariel requires nozzle reinforcement pads.
