COALVEX Gas Conditioning Architecture
Engineering Reference · Industrial & Process
Platform: COALVEX™
Technology: COALERIS™
Engineering Relationships
- COALVEX™ organizes gas conditioning around the liquid phase carried by natural-gas and industrial process-gas streams.
- COALERIS™ is the COALVEX™ family for fine liquid-aerosol and small-droplet coalescence and maps to TC-NG-01.
- Gas-Liquid Separation is the descriptive COALVEX™ path for free liquid, larger droplets and bulk or intermediate separation and maps to TC-NG-02.
- Bulk separation and fine coalescence are distinct mechanisms and may be staged when the incoming liquid load requires pre-separation before fine aerosol treatment.
- Treatment selection depends on gas composition, flow, pressure, temperature, liquid form and loading, droplet behavior, turndown, drainage and required downstream condition.
- Vessel architecture, application point and system configuration do not become independent technology marks.
Components
- Gas coalescing elements and media
- Bulk or intermediate separation internals where applicable
- Element-to-housing sealing interfaces
- Liquid drainage path
- Installed pressure vessel, separator, drains and instrumentation as system context
Problems
- Fine liquid aerosol carryover
- Free-liquid or large-droplet carryover
- Downstream compressor or equipment liquid exposure
- Poor drainage or liquid re-entrainment
- Unexpected differential-pressure rise
- Unstable separation across flow turndown
Diagnostic Methods
- Determine whether the incoming liquid challenge is fine aerosol, larger entrained droplets, free liquid or a combination.
- Review gas composition, pressure, temperature, flow rate and turndown.
- Characterize liquid loading, droplet behavior and liquid physical properties.
- Inspect element seating, sealing, vessel condition and the liquid drainage path.
- Distinguish coalescing-media problems from bulk-separation, drainage or vessel-operating problems.
