Hydrogen Sulfide Chemical Formula and the Molar mass of H2S

What is hydrogen sulfide? H2S is a naturally occurring chemical compound that is created in nature with the decay of organic material. Hydrogen sulfide formula is a chemical compound with a molecular formula comprised of (2) hydrogen atoms and (1) one sulfur atom. The formula is displayed as H2S. The gas is a colorless hydride gas and it is often known as the “Rotten egg gas”. This gas is very dangerous as it is poisonous and toxic to all forms of life. It is also very corrosive and flammable. The H2S molar mass is 34.1 g/mol and it has a melting point of -76 F (-60 C) and a melting point of –115.6F or (-82C).

Hydrogen sulfide gas is also created more often from a byproduct of a manufacturing process or the removal of water or wastewater treatment systems. In wastewater, as organic material decays H2S is released, captured, and treated to protect human lives, reduce corrosion, and reduce odor complaints. During the manufacturing operations at refineries, pulp mills, and mining hydrogen sulfide gas is produced. These higher levels of H2S are released during the manufacturing process and must be captured and neutralized to protect human life and prevent excessive corrosion. At higher concentrations, you cannot even smell the gas and it is not distinguishable as the “rotten egg gas” which makes it even more dangerous and drives the need for the equipment known as hydrogen sulfide scrubbers, and fume scrubbers, or odor control scrubbers.

According to the “Agency for Toxic Substance & Disease Registry” those who work within certain industries, are exposed daily to higher levels of hydrogen sulfide gas than the normal public. Because the gas is also heavier than air it will settle into lower places like manholes, tanks, and basements and it will travel across the ground filling in low-level areas. To protect the public OSHA has set guidelines and rules known as “Permissible Exposure Limits” (PEL). A PEL is a legal limit a worker may be exposed to a chemical substance. The PEL limit for hydrogen sulfide is ten parts per million (10 ppm) over eight hours.

Safety Precautions When Entering A Water Treatment Tower Or Tank

Posted by Anthony DeLoach, President on Sep 20, 2017 2:36:58 PM

Water treatment towers and storage tanks are high places that require special precautions when entering. While the majority of people who enter these locations for work can be trusted, there are some hazards that make it more important than usual to follow safety procedures.

These locations can get very hot and humid, and can also be filled with harmful chemicals and microorganisms that can cause serious health issues if inhaled or absorbed through the skin. Therefore, the general standard for workplace safety is much higher when entering locations like these.

Make sure you have read and understood the following information about safety when entering a water treatment plant. It will help you understand how to stay safe and protect yourself from harm when entering a water treatment plant. normal installation, maintenance, or even emergency repairs, it is often required to enter into a water treatment tower (degasifier, air stripper, decarbonator, or clear well/ storage tank). When this occurs, full safety protocols should be followed at all times, in accordance with OSHA regulations.  A tower or tank B classification is a "Confined Space" location. For more information visit the OSHA combined space regulations page.

In addition, there are other safety risks that an operator or technician can be exposed to while inside these types of closed locations. The risk can come from fumes of hydrogen sulfide (H2S), chlorine from an injection line, or a lack of oxygen O2. A proper confined space permit should be prepared and only technicians with proper training and certifications should enter into these types of confined spaces.
