COALVEX Gas Conditioning Architecture
Engineering Reference · Industrial & Process
Platform: COALVEX™
Technology: COALERIS™ · GASLIQ™
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.
- GASLIQ™ is the COALVEX™ Gas-Liquid Separation technology 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.
Operating Conditions
- Natural-gas or industrial process-gas duty
- Gas composition
- Operating and design pressure
- Temperature range
- Gas flow rate and turndown
- Aerosol or droplet size distribution
- Liquid loading and variability
- Drainage and liquid-removal behavior
Standards
- ISO 13686:2013 — natural-gas quality designation; process/gas-quality context rather than a filter-element certification.
- ISO 12500-1:2007 — oil-aerosol performance testing of coalescing filters in compressed-air systems only.
- ISO 8573-1:2010 — compressed-air purity classes for particles, water and oil where the duty is compressed air.
- ISO 8573-2:2018 — compressed-air oil-aerosol measurement where applicable.
- ISO 8573-9:2004 — compressed-air liquid-water measurement where applicable.
