H2STORY™

Optimised programmes for hydrogen sulphide control in process industries

Refineries and petrochemical plants have adapted to processing today’s high-sulphur crudes. However, low-quantities of hydrogen sulphide in the wastewater liquids can result in lethal levels being liberated to the air and must, therefore, be reduced to ensure the safety of operations and maintenance personnel. Hydrogen sulphide can also cause severe corrosion, which leads to high maintenance costs.

H2STORY is a controlled process that uses the benign VTX catalyst with a reagent to rapidly oxidise hydrogen sulphide and recalcitrant organic compounds.

Why use H2STORY?

  • H2STORY immediately controls hydrogen sulphide emissions to air
  • VTX is benign and has no special handling requirements
  • US Environmental Protection Agency has approved VTX for use in the environment
  • With the correct amount of oxidant, the target hydrogen sulphide and VTX catalyst are consumed to leave only carbon dioxide, elemental sulphur, salts and water
  • H2STORY is faster and more effective than alternative processes
  • Cost-effective
    • Simple design
    • Easily applied to existing equipment
    • No special construction
    • Minimal power requirements
  • No sludge: elemental sulphur is easily filtered out
  • Reduces corrosion-related maintenance costs

A proven process

Major refiners use H2STORY for removal of hydrogen sulphide. For example, a UK refinery presently controls 2,000 ppm hydrogen sulphide in 300-m3/hour plant drains using H2STORY. After dosing, a second sampling point within 10 m shows zero hydrogen sulphide.
