What is the convict?
Operation is the process of removing sulfur from something to prevent contamination. This chemical process, known as hydrodesulfurization or HDS, reduces sulfur dioxide emissions and converts them into sulfuric acid. Sulfuric acid is then used in car batteries and fertilizer. The most commonly required desulfurization process is in natural gas. For smoke gas, coal and oil, further convictions are required.
Natural gas designer is usually performed by adsorption. A natural carbon bed is used as a natural gas pipe filter. When the natural gas passes through the pipe, it passes through the activated carbon at the established interval. Sulfur is left and adsorbed to the activated carbon. Tests are performed regularly to ensure that sulfur levels remain at an acceptable level.
Smoke gas is a by -product of power plants and refers to the exhaust of fossil fuel combustion. The reduction of smoke gas is required to reduce the amount of sulfur dioxide into the air. It is a great factor in the formation of sour rainsE.
The machine called the washing machine is used to remove sulfur from the smoke gas. It works with a combination of sulfur with lime or limestone to form a compound or porridge. The porridge is then removed by absorbing the porridge and converting to the plaster, which is used to produce a wall plate or cement.
Coal sulfur is achieved in three ways. The most common method is density separation. The shaking of tables or preparations promotes the material and divided into smaller particles. The dirt is then removed. Commercial practices for large amounts of coal employ a coal spiral or cyclone that uses centrifugal power to separate coal from sulfur.
Another method is a flotation or flocculation. In this method, coal is immersed in the liquid. Mineral mass is lighter than coal, so it will float to the top, allowing the spinning of pollutants. The last method is magnetic susceptibility. This method goes through an electric PROudem through coal that attracts pyrite sulfur and works only on coal of fine particles.
Oil desulfurization works in two main ways. The first is similar to natural gas condemnation, as it also uses activated carbon filters. This method is usually used only if it has a relatively low, less than 50 ppm, at the beginning. The second method, a microbial sulfur, uses to remove sulfur compounds, which reduces air pollution during the refine process.
