Med-Lab Limited are authorised distributors for the Finnish Measurement Systems Limited (FMS) PORLA.

The PORLA is a Fully Automatic Analyser for measuring the Stability and Compatibility of Heavy Fuel and Crude Oils.

• ASTM Test Method D7112
• Analyzer performs complete analytical procedure fully automatically
• High automation level saves operator time and reduces costs
• Sample preparation time of 5 minutes
• Detector uses reflected light, sensitive to asphaltene particles
• No need to filter samples to remove coke particles and other contaminants
• Capable of analyzing oils with asphaltene content as low as 0.1%
• Ideally suited to Visbreaking and hydrocracking processes
• Reports the following values for each analysis performed
  o P-value
  o Solvent equivalent/flocculation ratio, FR5/1
  o Peptisability of asphaltenes, Pa
  o Peptizing power of oil medium, Po
  o FRmax
  o Xmin
  o Correlation coefficient (accuracy of result)
  o Solubility Blend Number, Sbn
  o Insolubility Number, In
• Plots graph for quick and easy checking of result
• Determines compatibility parameters according to Exxon Mobil blending model
  o Correlation coefficient (accuracy of result)
  o Solubility Blend Number, Sbn
  o Can be applied to blending of crude oils, marine fuel oils, etc
• Very quick to clean detector (1 minute)
• Desk-top laboratory analyser
• Analyser simple to operate
• Minimal operator time needed for sample preparation
• Any combination of aromatic and paraffinic solvents can be used
• Analysis performed at slightly elevated temperatures to reduce reaction time
• 3-point titration typically takes 90 minutes
• Clean cycle performed between each titration
• Thorough clean cycle performed at end of each test leaving instrument ready for next analysis
• Increased precision compared to manual and other methods - Reproducibility and Repeatability of 0.08 at P-value of 1.5
• Results stored on PC hard drive, possible to print hard copy
• Allows production process to operate closer to severity limit - huge cost savings possible!
• Payback on investment in 6-8 months for time savings made on operator time
• Payback possible in 1-2 months through greater optimisation of process
• Installation and training, including application build-up in customer's laboratory
