Hydrogen Sulfide Dangers to the
Environment
Hydrogen Sulfide is dangerous to the environment, colorless, very poisonous,
highly flammable gas with the characteristic foul odor of rotten eggs. Heavier
than air, it tends to accumulate at the bottom of poorly ventilated spaces.
Although very pungent at first, it quickly deadens the sense of smell, so
potential workers may be unaware of its presence until it is too late. 800 ppmv
is the lethal concentration for 50% of humans for 5 minutes exposure.
This Hydrogen Sulfide gas is a
common off-gas which is produced in the Steel and Mining industry. At even very
low concentration levels H2S is considered a fatal gas. You have to do highly
paid job as a petroleum engineer you must have Short
courses in Islamabad. H2S is commonly reduced by thermal
oxidation to SO2 and SO3 for possible usage in other plant processes or if not
utilized for other applications may be removed by the use of a wet scrubber.
Design considerations should also be
given to the type and metal thickness to obtain high outlet temperatures. These
temperatures need to be above any possible condensation levels of by-products,
this will reduce any formation of sulfuric acid within the exhaust system. With
the high outlet temperatures the exhaust may be used to generate high pressure
steam which may be used in steam operations or to power a turbine creating
offset electricity.
In order to work safely around
Hydrogen Sulfide, you must do Shortcourses in Islamabad first know what it is. H2S is a colorless gas with an odor
that is often said to smell like rotten eggs. It is commonly encountered in the
oil and petrochemical industry. This gas is highly dangerous. It is highly
flammable, but the biggest danger comes from its toxicity. In some
concentrations, it can knock you out in one breath.
Exposure can cause many health
problems depending on how long you are exposed and the concentration level of
the gas. In concentrations of 100-400 parts per million, it can make you
nauseated and disoriented. Long term exposure at these levels can cause
chemical pneumonia. In concentrations over 500 PPM, it can make you pass out
and go into respiratory arrest even from a short exposure.
So you can see that it is pretty
important to protect yourself. You can do so with proper gas detection
equipment, monitoring, engineering controls, PPE, having a rescue and
contingency plan and following all safe work practices. If you work around
hydrogen sulfide, it is important for you to receive the proper training from Short courses in Islamabad
