H2S Gas in Oilfields
  • The world has witnessed a substantial increase in
    EP of crude oil to meet the need for
    globalization, leading to drilling of deemed
    undesirable sites, owing to the presence of
    higher concentration of acidic gases like
    hydrogen sulphide, carbon dioxide, etc. These
    hazardous gases require proper measures before
    disposal or scavenging. Of these, Hydrogen
    sulphide/ H2S is the most threatening one,
    especially in confined or ill ventilated places.

  • A substantial increase has been seen in Crude Oil
    Exploration to meet the call of Modern
    infrastructures and technology, leading to
    drilling of undesirable sites, which were once
    considered infeasible due to the presence of
    higher concentration of acidic gases like
    Hydrogen Sulfide, Carbon Dioxide, etc. Of all the
    acidic gases coming out during extraction, H2S is
    the most threatening one.

  • Capital investment in oilfields with respect to
    utilities associated, production, infrastructures
    and assets valuation is huge, giving no scope of
    any sort of lag or halt. Since this gas is
    naturally occurring, Measures have to be taken to
    combat or rather control the effects of this gas,
    one of them being application of H2S scavengers.
    These chemicals on application removes hydrogen
    sulfide gas from the drilling site that comes out
    with crude.

But, H2S Gas has consequences!
  • Less than 20 ppm of H2S concentration may cause
    eye irritation, throat soreness and burning,
    dizziness. 80 100 ppm may cause serious damage
    to exposed organs including severe vomiting and
    breathlessness. More than 500 ppm may cause
    instant loss of consciousness.

H2S Scavenging Chemicals in Oilfields
  • H2S scavenger forms an inert compound on reaction
    with hydrogen sulfide gas, improving safety,
    protect equipment and meet oil and gas
    specifications. It contributes to high
    performance, exerting no impact on further
    processing at Oil and Gas facilities. This
    product has found global acceptance from the
    crude unit engineers during gas lift injection
    and chemical injection and other offshore
    production applications.
