Raman Spectroscopy

Raman Applications

The chemical specificity combined with both the ease of on-line installation and real-time analysis rates have made Raman an attractive choice for petrochemical process monitoring and control. Using the AirHead™ or Pilot™ probes lines Raman analysis of typical petrochemical process can be made in situ. Examples include

  1. Cracking
  2. Reforming
  3. Solvent Extractions
  4. BTEX materials production and xylene separations
  5. C4 Processing
  6. Aromatic Processing
  7. Blending

For the above general processes Raman can be used to monitor chemical purity, and distillation column operation (both pre- and during steady state (equilibrium) operation). Raman is capable of measuring materials as solid, liquid, gas, vapor, or slurry. Chemical application areas include:

  1. Benzene, toluene, ethylbenzene, and xylenes
  2. Olefins, ethylene, propylene
  3. Cyclohexane,
  4. C4 Hydrocarbons
  5. Cumene
  6. Styrene
  7. Acrylonitrile
  8. Gasoline (octane, blending, oxygenates)

One of the other associated categories of petrochemicals is polymers, oligomers, and polymer pre-cursors.  Raman can be used to analyze such commercially important chemicals as:

  1. Low Density Polyethylene (LDPL)
  2. Linear Low Density Polyethylene (LLDPE)
  3. High Density Polyethylene (HDPE)
  4. Polypropylene (PP)
  5. Polyvinyl Chloride (PVC)
  6. Polystyrene (PS)
  7. Styene
  8. Butadiene
  9. Olefins
