PyGas Probes /Reflux Probes

Analysis of gas constituents in a running plant can be extremely challenging due to harsh and complex process conditions and stringent measurement requirements. Process Analytik Instruments presents the Distillation Gas Sample Probe from Ametek, USA, for critical and difficult processes such as:

• Gas sampling in decoke operations
• Gas sampling in Fluidized Catalytic Cracking Units (FCCU)
• Gas sampling in syngas
• Pyrolysis gas sampling

The Distillation Gas Sample Probe is ideal for installation in decoke headers, hot, wet, or dirty processes, pyrolysis gases, heavy particulate removal, and fine carbon removal. Also known as a Reflux Probe or Pygas Probe, its high-performance design is suitable for use in ethylene furnaces, FCCUs, and coke ovens. Key features that ensure high performance and uninterrupted operation include:

• Accurate outlet gas temperature control (±1°F) with optional Electronic Controller (EC)
• Dual pneumatic controllers available
• Prevention of liquid carryover
• Remote monitoring
• Self-cleaning separator
• Reduced maintenance requirements
• Removable one-piece 316 SS separator
• Automatic sampler shutdown on high inlet or outlet temperature (with optional EC)
• High R-factor cooling chamber
• Probe can be sized to supply 1–5 LPM of sample
• Suitable for hazardous areas

The Universal Analyzers Model 1221 Distillation Sample Probe provides exceptional performance due to:

• Pre-fabricated and integral insulation, requiring no onsite installation
• High-powered cooling with single or dual-vortex or electronic cooling
• Self-cleaning internals requiring minimal maintenance over long periods
• High-temperature stability of conditioned gas for accurate analysis
• Self-diagnostics, remote monitoring, configurable alarms, and DCS integration capability
• Options for pneumatic or electronic operation and control
