High-efficiency desulfurization catalyst, also known as desulfurization synergist, is fluffy powder, soluble in water, and needs to be stored in a cool and dry place. It can be used in limestone desulfurization, for natural gas, coal gas and other desulfurization, and can also be widely used in the purification of gasoline and liquid hydrocarbons. So what are the working principles and advantages of high-efficiency desulfurization catalysts? The following Henan Borage Industry will introduce the working principle and advantages of high-efficiency desulfurization catalysts
1. The working principle of high-efficiency desulfurization catalyst.
The limestone is prepared into a certain concentration of limestone slurry, and the desulfurization additive is added, it is stirred evenly, and then the limestone slurry pump enters the desulfurization reaction tower, atomized into fine droplets and the flue gas in the boiler for mass transfer, SO2 is absorbed by limestone milk, and the purified gas is discharged from the flue. In the desulfurization process, the reaction rate between limestone and sulfur is limited by the dissolution rate of CaCO3, and when the solubility of CaCO3 in water is small, the dissolution of CaCO3 in water can be improved.
2. Advantages of high-efficiency desulfurization catalysts
1. Improve desulfurization efficiency
Improve the gas-liquid mass transfer rate of sulfur dioxide, strengthen the absorption of sulfur dioxide and improve the desulfurization rate, without the need for equipment expansion and transformation. At the gas-liquid interface, the catalyst can combine a large number of H+ ions produced by SO2 dissolution, so that H+ ions are transferred from the liquid film to the liquid phase body, and the slurry pH will not drop too quickly due to the dissolution of SO2, and the gas phase resistance will be reduced, which will promote SO2 absorption.
2. Reduce costs
The addition of desulfurization catalyst provides basic groups, enhances the liquid film mass transfer factor, improves the desulfurization efficiency, promotes the dissolution and dissociation rate of CaCO3, reduces the liquid phase resistance and fuel usage, effectively controls the cost and increases the flexibility and stability of the main engine coal adjustment and desulfurization system.
3. Reduce equipment blockage
The active ingredients in the high-efficiency desulfurization catalyst can increase the dispersibility of limestone and improve the surface activity of limestone, thereby prompting the equipment to reduce its sedimentation rate, not tolerate scaling, keep the equipment in an efficient state, and improve efficiency.
The above is an introduction to the working principle and advantages of high-efficiency desulfurization catalysts, I hope it will be helpful to you.
