An excerpt from ISNetworld® RAVS®* Safety plan Hydrogen Sulfide H2S Program
H2S Awareness and Training
Sulfur may be present in crude oil as hydrogen sulfide (H2S), as compounds (e.g.,
mercaptans, sulfides, disulfides, thiophenes, etc.), or as elemental sulfur. Each crude oil
has different amounts and types of sulfur compounds, but as a rule the proportion, stability, and complexity of the compounds are greater in heavier crude-oil fractions. As part of the work of Replace with Company Name, our employees may be exposed to H2S - especially when working on corroded pipe repairs. Hydrogen sulfide is a primary contributor to corrosion in refinery processing units and piping. Other corrosive substances are elemental sulfur and mercaptans. Possible locations where employees may be exposed to H2S during their job functions may be, but not limited to: Drilling Operations, Recycled Drilling Mud, Water from sour crude wells, Blowouts, Tank Gauging (tanks at producing, pipeline & refining operations), Field Maintenance, Tank batteries and wells. [1]
. Hydrogen Sulfide is a colorless gas at normal temperature and pressure with an odor similar to that of rotten eggs, H2S is also soluble in water, and can be found in wastewater. In it’s pure form, H2S is flammable. Moreover, the corrosive sulfur compounds have an obnoxious odor. However, presence of this gas may deaden the sense of smell so odor alone cannot be used for detection. In cases of extreme low temperature and/ or high pressure H2S may be a liquid. [2]
SOUR GAS
Natural gas that contains corrosive, sulfur-bearing compounds such as hydrogen sulfide and mercaptans.
SWEETENING
Processes that either remove obnoxious sulfur compounds (primarily hydrogen
sulfide, mercaptans, and thiophens) from petroleum fractions or streams, or convert them, as in the case of mercaptans, to odorless disulfides to improve odor, color, and oxidation stability.
