H2S Vapour Phase Processor (VPP)

Part Number SA4015-0

The Vapour Phase Processor (VPP) is used with the H2S Analyser and removes components that may affect the accuracy of the results, such as toluene, xylene, thiols (mercaptans) and alkyl sulphides.

The VPP accessory is designed to promote the safer use of residual and distillate fuels, recognising the fact that the industry is entering into a new realm of multi-blend products driven by increasing environmental regulation.

The H2S Analyser with VPP is an excellent tool for supporting product Quality Control and safety, ensuring you are given better protection against the supply of poor quality fuels. It is also ideal for both product remediation treatment of feedstock components and off-spec products with fast repeat sample measurement capability.

ADDITIONAL INFORMATION

H2S Analysis of Crude Oil

Many crude oils come out of the well with high levels of H2S, but a stabilisation process usually reduces this level so the fuel is safe to handle, store and transport.

The H2S Analyser combined with the VPP offers a fast and robust means of determining H2S levels to ensure efficient treatment of crudes. The instrument provides a cost effective alternative to traditional methods which cannot offer a true indication of H2S, especially at low gas levels.

How does the VPP work?

Gases emitted from the H2S Analyser test vessel are passed through a cooled sorbent cartridge before they are measured by the electrochemical sensor. Hydrogen Sulfide passes through the sorbent cartridge whereas methyl mercaptans, dimethyl sulphide and other volatile chemicals are slowed or trapped by the cartridge to avoid contamination.
