Hydrogen sulfide is a byproduct and a pollutant gas. It is produced by various industrial processes. These include oil drilling and various other such processes. This is a health hazard and inhaling large quantities of this gas could lead to unconsciousness and even death in a few cases. There are instances where even inhaling of small quantities could lead to health challenges and many physically weak persons could also face the danger of death or permanent disability. Hydrogen sulfide gives out a foul odor that resembles a rotten-egg. It is very powerful and can be noticed even in small quantities of 2 parts per billion. This is perhaps equal to around 1 milliliter of gas in a lecture hall that can seat 100 people. Hence, it is quite important to find out ways to neutralize this gas during and after the completion of the manufacturing and other processes.
How Is Neutralization Done?
Sodium bicarbonate solution is considered one of the best options for neutralizing Hydrogen sulfate. Sodium bicarbonate in the recommended quantities has to be dissolved in water. There are a few other salts such as potassium bicarbonate and sodium bicarbonate which also could work. Sodium bicarbonate is the best option because it is very stable and highly soluble in water. It works well in small quantities. A solution of sodium bicarbonate of 0.01 grams to 0.25 grams per mole of water is good enough to neutralize hydrogen sulfide.
The Right Process Has To Be Followed
There are some laid down protocols, methods, and processes when it comes to removing hydrogen sulfide from different sources. The same must be followed strictly. It would always be advisable to have this process done by professionals rather than trying it yourself. A gas containing carbon dioxide and hydrogen sulfide should be brought in contact with water that is laden with baking soda or calcium bicarbonate. This can be done in many ways including spraying of the water solution over the container that contains hydrogen sulfide amongst other gaseous substances. You could also send the gas bubbling through a vessel holding the water that has the right mixture of sodium bicarbonate.
It Is Complex And Difficult
However, we need to bear in mind that it is a highly complex and difficult job and doing it without the right protection and expertise would not be the best way forward. Many professionals could help in finding out the right solution and approach that could help in removing hydrogen sulfide from biogas, water, oil and other sources. There are also other absorbents in the form of powder and liquids that could also be tried out. But at the end of the day, there is no denying the fact that it is essential and vital to ensure that the main product is made free during and after the manufacturing and conversion process. The harmful side effects are quite dangerous and they have been mentioned earlier in the article. Hence, there cannot be any compromise on this under any circumstances. Professional approach with the right tools and methods is the best way forward
