Flue gas desulfurization (FGD) systems have been used for decades for the treatment of natural gas combustion products before their release into the atmosphere. The process involves passing carbon dioxide through activated carbon or zeolite media to remove sulphur compounds and nitrogen oxides, leaving behind only pure carbon monoxide with combustible properties similar to those of natural gas. This post will discuss how this system works and its advantages.
What is Flue Gas Desulfurization System?
A flue gas desulfurization system is a process used to remove sulphur dioxide from the exhaust flue gases of coal-fired power plants. The system works by injecting a dry sorbent into the flue gas stream. The sulphur dioxide reacts with the sorbent to form a solid compound, which is then removed from the flue gas.
The main benefit of this process is that it reduces the emission of sulphur dioxide, which is a significant contributor to the acid rain & smog. In addition, the system can also help power plants meet stringent environmental regulations.
How does Flue Gas Desulfurization System Works?
Flue Gas Desulfurization System is a technology that can be used to treat flue gas from a power plant. The flue gas contains Sulphur dioxide & Sulphur trioxide, which are toxic gases that are released in significant quantities by conventional fossil fuel power plants.
The Flue Gas Desulfurization System uses one of two methods:
1. Carbon Dioxide Removal: This method involves capturing the Sulphur dioxide gas with carbon dioxide and removing it from the system. The captured gas is sent to a sequestration site where it is stored until the next step of the process. Which involves injecting it into underground rock formations for storage.
2. Amine Removal: This method involves reacting ammonia with hydrogen supplied to produce non-toxic hydrogen supplied and nitrogen gas. Which are then released into the atmosphere instead of being emitted by traditional power plants.
Advantages of Flue Gas Desulfurization System
Flue gas desulfurization systems are an excellent way to treat the pollution created by coal-fired power plants. In addition to being a greener way of producing energy, they also have many other benefits.
The flue gas desulfurization system is a clean and efficient way to treat pollutants in the flue gas from coal-fired power plants. The pollutants it can remove include sulphur dioxide and nitrogen oxide, both harmful to human health’s. It also removes CO2 from the air by turning it into carbon monoxide and water vapour. This reduces the amount of greenhouse gases present in the atmosphere and improves air quality. Removing these pollutants can reduce asthma attacks and respiratory problems caused by smog pollution.
There are also various other benefits of using this type of system instead of traditional technology like wet scrubbers or filters:
It doesn’t require any modifications to existing equipment or facilities; therefore. It can be used on existing plants without any additional costs or time spent modifying them (you just need a new fuel treatment system). The process is straightforward: after adding water into the system through one pipe. You simply let it run until no more bubbles are coming out of the other pipe. This means that it’s straightforward to use and requires no special training or skills to operate; anyone can do it!
Flue gas desulfurization systems are essential equipment which removes the toxic gases from power plants’ flue gases. This equipment is widely used to reduce the emissions of Sulphur dioxide (SO2), nitrogen oxide (NOX). And other harmful gases released by fossil-fueled power plants. The system is used in many countries around the world and is considered one of the most effective methods of reducing air pollution. It helps to improve people’s health, reduces greenhouse gas emissions and makes our planet more sustainable.
