Desulfurization of self-prepared chemical boilers: key points for selecting high-efficiency magnesium oxide desulfurizers
In the chemical industry, the desulfurization treatment of self-provided boilers is a key link, and the selection of efficient magnesium oxide desulfurizer plays a vital role in it. So what are the key factors in selection?
1. Desulfurization efficiency
Desulfurization efficiency is an important factor that must be considered when selecting magnesium oxide desulfurizer. Magnesium-based desulfurizer has high activity and strong adsorption capacity, and its desulfurization efficiency can reach more than 95%. This characteristic makes it excellent at removing sulfur dioxide (SO₂) from flue gas and can effectively purify flue gas.
2. Response ability
The dissolved alkalinity of magnesium ions is much higher than that of calcium ions. This characteristic makes the reactivity of magnesium-based desulfurizers dozens of times higher than that of calcium-based desulfurizers. Its desulfurization efficiency can reach more than 99%, and the amount of spray water required is only 1/3 of calcium-based desulfurization. The reduction in spray water volume can significantly reduce power consumption and has obvious advantages in energy conservation and emission reduction.
3. Operation reliability
The products generated by magnesium-based desulfurization have high solubility and are not prone to sedimentation. This means that problems such as scaling, caking, and clogging are less likely to occur in the entire desulfurization system. The system operation is more reliable, and the corresponding maintenance work becomes easier, reducing downtime caused by equipment failure and improving production efficiency.
4. Cost-effectiveness
Although the price of magnesium oxide is higher than that of calcium oxide, the amount of magnesium oxide required to remove the same amount of SO₂ is significantly reduced. Moreover, magnesium oxide is supplied in powder form, which simplifies the desulfurizer supply system, thereby further reducing the cost of the system. From an overall cost-effectiveness perspective, magnesium oxide desulfurizer has unique advantages.
5. Environmental protection characteristics
When choosing a desulfurizer, environmental protection characteristics cannot be ignored. Choose products that are safe and environmentally friendly. They are easy to store, have no corrosive effect on desulfurization equipment, and will not cause harm to operators. Such desulfurizers not only have positive significance for protecting the environment, but also ensure the safety of operators during work.
6. Technical parameters
The technical parameters of a desulfurizer are key to determining its suitability for a specific application. Parameters like magnesium hydroxide content, average particle size, pH, density, etc. all need to be taken into consideration. Only when these parameters meet the requirements can the desulfurizer be ensured to perform optimally in the desulfurization treatment of self-provided boilers.
7. By-product recycling
The magnesium-based process has unique advantages. Its direct by-product is magnesium sulfite, which will form magnesium sulfate after oxidation. Both by-products have a certain market value and can be reasonably utilized based on technical and economic comparisons and the feasibility of specific projects. This not only reduces waste emissions, but also brings certain economic benefits to the company.
8. Supplier selection
Choosing a reputable supplier is crucial. Such suppliers can guarantee stable quality of desulfurizers and no interruption in supply. Stable quality and supply are the basis for ensuring the continued and effective implementation of self-provided boiler desulfurization treatment.
9. Customized services
Finding a supplier that can provide customized desulfurization solutions is a wise choice. Different chemical companies may have different specific needs, and customized services can better meet these needs and improve the pertinence and effectiveness of desulfurization treatment.
