Hydrogen sulphide is a flammable, colourless gas with a characteristic odour and has an offensive smell of rotten eggs. Hydrogen sulfide gas (H2S) can give water a “rotten egg” taste or odour. It is a natural product of decayed vegetation, hydrogen sulphide can be seen in groundwater. Depending on the percentage of hydrogen sulphide present, it can produce a moderate or heavy sulphur odour.
Uses of H2S
Hydrogen sulphide gas also can result from industrial activities, such as
- food processing
- coke ovens
- kraft paper mills
- petroleum refineries.
Hydrogen sulphide gas is also known as “sewer gas” because it is often produced by the breakdown of waste material. Sewer gas, stink wet, swamp gas, and manure gas provide some common names for the gas. Naturally, it occurs in crude oil, natural gas, and hot springs.
