Kaiser Raman Optograf Process Analyzer

The design of the Optograf process analyzer incorporates customer requirements for serviceability and hazard-area certification, provides a compact footprint, and minimizes utilities consumption. The high optical efficiency of the Optograf process Raman analyzer makes it ideal for measurement of gas-phase samples.

Description

Turn-key process Raman analyzer for quantitative chemical composition measurements

The Kaiser Raman Optograf process analyzer is an industry-leading, turn-key, laser-based analyzer that provides quantitative chemical composition measurements using Raman spectroscopy. The design of the Optograf process analyzer incorporates customer requirements for serviceability and hazard-area certification, provides a compact footprint, and minimizes utilities consumption. The high optical efficiency of the Optograf process Raman analyzer makes it ideal for measurement of gas-phase samples.


Benefits

  • Non-destructive analysis of gases, including homonuclear diatomics (H2, N2, O2)
  • Compact, smaller than most wall-mount GCs
  • Can replace up to four traditional analyzers with a single base unit and four probes
  • Rugged with minimal utility requirements, no sample transport, and no consumables (columns, valves, gases, pumps)
  • Minimal analyzer technician time with maximum technician safety (no toxic gases are transported to the analyzer)
  • Measures four streams simultaneously for faster multi-channel results
  • -20°C to + 50°C operating environment

Field of application

Process measurement points:

  • Steam methane reformers
  • Gasifiers (coal, petcoke, waste, biomass)
  • Shift converters
  • Hydrotreaters
  • Hydrocrackers
  • CO2 removal
  • Finished product synthesis loops
