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.
