H2S Vapour Phase Processor (VPP)

Part Number SA4018-0

IP 570 Procedure A - 'Determination of Hydrogen Sulfide in Fuel Oil'

The H2S Analyser (SA4000-3) was originally developed to offer effective, rapid measurement of H2S in petroleum products. The VPP was subsequently developed for use with the H2S Analyser to improve precision and accuracy.

IP 570 procedure A includes the VPP accessory which provides the marine industry with a more robust specification tool for monitoring H2S. This is achieved by removing any interfering chemicals such as toluene, xylene or Mercaptans which can damage the sensor and ‘interfere’ with readings. The method change towards including 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 users 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.
