Flue Gas Desulfurization: The Use of Scrubbers
The Need for Flue Gas Desulfurization
Required in all industrial refineries, manufacturing industries, processing plants, and the like, this is an important process in order to remove or at least reduce the amount of sulfur dioxide (SO2) found in flue gases. This removal or reduction determines the sustainability of the processes in relation to ensuring safety and cleanliness in their respective working environment. Thereby, emissions of toxins are maintained at the lowest and safest level.
The Emission of Sulfur Dioxide
In processing plants, for example, where coal, oil and the like are used, contain great levels of sulfur, which when burned produces sulfur dioxide that is released as flue gas. The electric sector, transportation and other industries are also known for using fossil fuels.
The Effect of Sulfur Dioxide in Communities
The emission of flue gas is very dangerous to humans and animals. Aside from the fact that it can react with other harmful substances, it can irritate one's respiratory system starting from the noise down to the throat and lungs, which with sustained exposure can lead to more severe health conditions. Flue gas that contains sulfur dioxide is highly pollutant too in the air we breathe. Furthermore, it activates the falling of acid rain that kills the different life-forms. It is also the major contributor to paint peeling, steel bridges corroding, and statues weathering.
The Removal Process of SO2
Since SO2 is acidic in nature, neutralization is important before any disposal is made. To neutralize, a sorbent that is made out of alkaline is applied, which makes the pH level of SO2 neutral. A scrubber system is often implemented in many industrial plants as it is one of the best methods to reduce or remove SO2 emissions.
The Flue Gas Desulfurization Process
This desulfurization process makes use of scrubbers to remove around fifty to ninety-eight percent of SO2 emissions; with wet scrubbing producing the highest removal efficacy rate and dry scrubbing as the lowest. Wet scrubbers often utilize silicon carbide nozzle or known as SiSiC as the key component of the flue gas desulfurization process in many power plants and boilers. Aside from this material that lasts long, it is very durable as well as resistant to corrosion and high heat.
The Recent Regulations
World environmental organizations are all one in implementing strict rules and legal regulations concerning decreasing the release of sulfur dioxide; thus, desulfurization has been a priority more than ever for many countries.
