As we are Specialist in Crude Oil & Petroleum Products analysis , please find Below Our Most important instruments for these tests:

1- Crude Oil Sediment Centrifuge According to ASTM D91, D96 and D4007

2- H2S analyzer for Crude Oil

The measuring principle of H2S Analyzer 320 based on DyMS method. The instrument has one – optional two – storage and one measuring containers, where the sample will be mixed permanently and hold on temperature up to +200 °C. The sample will be pumped into the measurement container – loaded with a high boiling point solvent – and mixed continuously. Afterwards the H2S is stripped off by purging nitrogen through the liquid. The mass transfer is  improved and more H2S can be detected compared to other methods.

The use of inert gas nitrogen avoids oxidation of true H2S. The H2S concentration is finally detected by a specific sensor. In general a measurement requires max. 15 minutes. The results will be recorded, calculated and printed. 
Further sulphur compounds like light mercaptans and SO2may be measured simultaneously when respective sensors have been installed. 
The set-up of H2S Analyser DyMS further allows the preparation of a second test sample while the first is still running. This feature increase the test flexibility and frequency. Just the DyMS method enables a wide protection of safety, environmental and corrosion-related problems.

• ACCURA: Sampling Device

The ACCURA sampling device is designed for fully automated analysis of gaseous and pressurized liquid hydrocarbon streams for MultiTek and Gas Chromatography applications. It provides these key benefits through:

  • Highest accuracy and precision through uncompromised sample integrity
  • Easy to use
  • Maximum operator safety
  • Can be used for MultiTek and GC, gas and liquids
  • Repeated injections in one run (MultiTek only)

When analyzing Liquid Pressurized Gases (LPG) with Gas Chromatography or Elemental Analysis, the most challenging task is to maintain sample integrity. Uncontrolled expansion of pressurized or liquefied gases often leads to discrimination: the perceived sample composition changes.
Accura is a temperature and pressure controlled vaporizing injection device that respects sample integrity completely. The resulting data are more accurate and precise, which translates in a narrower product specification and better refining profit.
LPG and hydrocarbon gases are extremely flammable and therefore need to be handled with great care. Accura identifies when sample lines are depressurized after analysis, signaling the sample bomb can be disconnected safely
