    • Greener approach by KOC
      Shift mode of supply to Bulk containers from drums
      Mega Storage facility for 3 months stock- KD 14 million
      Chemicals selection based on Hazard classification
      Lab Screening/ Field trials for efficiency
      lab testing –innovative techniques eliminate CFC solvents
      Data capture Sahala – global award for DM

    • BULK HANDLING CHEMICAL- ADVANTAGES
      HSE improvement, cleaner assets
      KOC image boost as first implementer in GCC/world?
      No more empty drums accumulation
      No more chemical left over in the drums- SAVINGS
      No more expired chemical drums
      No more chemical spillage due to rupture of drums
      Safe Chemical Handling- no rolling of drums, fumes
      Better interaction with chemical
      no shortage of chemicals- high volume stock available
    • 3. Chemicals selection/classification:
    • 4. Chemical screening- example of corrosion inhibitor
      Corrosion Inhibitor Selection
    • Corrosion Inhibitor Dosage Rates and Residuals
    • Corrosion Rates –sample

    • Current methods: Oil in water
       EPA US-1664A- HEM (Hexane Extractable Material)- light ends evaporation.
      North sea- OSPAR-Oslo Paris convention new pentane extraction followed by GC-FID  
      Kuwait – pure analytical grade chloroform/ S-316 solvent

    • New Equipment
      SCF OIW analyzer
      Gas chromatograph
      FLASH POINT
      H2S ANALYZER
    • The TD-500D is a dual channel, handheld fluorometer designed for quick easy &reliable measurement of Crude oil
      It is ‘NO SOLVENT’ Method Compatible with all popular solvent extraction methods .
      The TD-500D responds to the fluorescent aromatic compounds in the target hydrocarbon.
      The instrument must be calibrated by measuring the intensity of fluorescent light that is generated by a known concentration of hydrocarbon.
      Once calibrated, the instrument converts the fluorescent light intensity from unknown sample into units of concentration.
      • The ‘No Solvent Method’ makes possible to perform Oil in water analyses by making fluorescence measurement directly on the produced water samples .
      • No Organic solvents are required.
      • The method is based upon the addition of a proprietary surfactant to the sample followed by heating, cooling & filtered into a measurement cuvette. The OIW Sample contains dispersed oil that has been solubilized by OIW Surfactant.
      • A second sample called WSO sample, contains no surfactant . It is simply filtered into a measurement cuvette to remove dispersed oil, leaving only WSO.
      • Both the OIW &WSO cuvettes are measured by the TD-500D.
      • The dispersed oil concentration is calculated by subtracting the ‘WSO’ measurement from the ‘OIW’ measurement. The result is reported in ppm.
      • Usage of Organic solvents like Chloroform, Hexane , xylene was avoided instead a OIW Surfactant was used.
      • Minimum Detection limit is <1 ppm for most oils.
