Recent advancements in the production and quality of fertilisers have expanded the opportunities for agricultural plants, necessitating the need for efficient air pollution control of harmful emissions from fertiliser manufacturers.
Scrubbers are traditionally pollution control technologies that use liquid to remove undesired particles from a gas stream. Scrubber systems, which include chemical and gas scrubbers, are a variety of air pollution management technologies.
Once they pass into the atmosphere, scrubbers remove undesirable gases and particulates from industrial smokestacks.
Using a gas scrubber in particular situations can make it possible to recover some raw materials following treatment. The adaptability of a gas scrubber in various settings is a huge benefit. Surface treatment, the chemical sector, and the pharmaceutical business are all included.
The equipment works by contacting a washing liquid with a gas stream. Certain gaseous elements dissolve and stay in the water as a result of this contact. For best scrubbing system for fertilizer plants contact Fibrograts.
Wet Scrubbers: In wet scrubbers, sulfur-containing particles are captured as the contaminated gases are forced to travel through a wet limestone slurry. These can be utilized to control inorganic gases including SO2, H2S, NH3, and other chlorides and fluorides, along with particulate matter smaller than 10 micrometres. Using wet scrubbers to reduce volatile organic compounds, or VOCs, may be beneficial.
The impurities condense during condensation washing, making them simple to remove. Impingement plate scrubbers push the pollutants up a vertical chamber, while sulfur-capturing water cascades down the chamber’s sides. Wet scrubber systems are typically used in coal-fired power plants with scrubbers.
Dry Scrubbers: Under the ideal circumstances, dry scrubbers can remove SO2 with an efficiency of more than 90%, but they can only be used in small- to medium-sized power plants with a capacity of about 200 MW. of the 120.000 megawatts of power produced by scrubber-equipped coal-fired power plants.
Additionally, only 16,200 megawatts are generated by dry scrubber facilities. Utilizing this technique has some benefits, such as low water usage and waste disposal expenses. Heavy metals, HF, HCL, and polycyclic aromatic hydrocarbons (PAHs), in addition to other contaminants, are also handled by dry scrubbers.
Scrubbers are exceptionally effective tools for reducing air pollution and can remove more than 95% of the SO2 from emissions from power plants’ stacks. In actuality, SO2 removal efficiency can occasionally reach 98 to 99 percent. Advanced scrubbing system for fertilizer plants frequently achieve targeted efficiency of greater than 95%.
