Simple and Practical Guide for Operators
Designed for offshore field operators with high school education level.
To explain RVP and H2S topics in a clear, simple, and field-relevant way.
RVP is a measure of a liquid's tendency to evaporate, especially for petroleum products.
Used to understand volatility and handling safety of fuels.
Higher temperature or lighter molecules mean higher vapor pressure.
RVP is measured using a standardized method at 100°F.
High RVP may cause vapor lock in engines or pumps.
Storage tanks may build dangerous pressure if RVP is too high.
A toxic, flammable gas with a rotten egg smell, commonly found in oilfields.
H2S can cause health issues or death at high concentrations.
H2S forms naturally from the breakdown of organic materials underground.
Heavier than air, it can collect in low-lying areas.
Even small amounts can affect health; higher levels are fatal.
H2S damages metal, leading to leaks or equipment failure.
Used to reduce H2S content in oil, gas, and water.
Triazine is widely used as a scavenger.
Triazine reacts with H2S to form non-toxic solids or liquids.
Works well but must be dosed properly for effectiveness.
Triazine is injected where H2S levels are expected or detected.
Field staff must check H2S levels before and after injection.
Digital devices showing real-time H2S concentration.
Color-changing tubes used with hand pumps for spot checks.
Know RVP to handle fuels safely; use scavengers to control H2S.
Always test for gases and follow safety protocols in the field.
