Why does sulfur turn black?
Thread Content
The sulfur produced by our factory is black, and the amount of slag generated is greater than that of sulfur. What could be the reason for this?
At the beginning of operation of the device, carbon buildup occurred as the system temperature rose. Or there is more hydrocarbon (oil) in the acidic gas zone.
There is a lot of carbon deposit or acidic gases containing hydrocarbons (oil); check for any changes in the oiling procedures
The gas contains a high amount of tar and naphthalene impurities
If there is a high amount of oil in the gas, it’s necessary to check the effectiveness of the spraying in the gas collection system, as well as the level of blockages. It’s also important to assess the efficiency of separating tar from ammonia water, and to determine whether the ammonia water contains a high level of oil. If there are frequent blockages, and the tar exiting the mechanical clarification tank has a high water content, high-temperature heating will be required to remove the water. If the quality of the ammonia water is poor, this indicates that the separation process isn’t effective, resulting in ammonia water with high oil content and poor quality. Clogged nozzles can also affect the spraying efficiency. We have a technology that can improve the separation of tar from ammonia water, increasing its efficiency. With just a small amount of this substance used, it’s possible to keep the water content in the tar at below 4%, and even below 1% in some cases. This allows the product to be sold directly, reducing steam consumption, improving the quality of the recycled ammonia water, lowering the rate of nozzle clogging, and enhancing the spraying efficiency. As a result, the quality of the gas improves, which in turn leads to better overall performance, reduced resistance, and lower energy costs. If needed, you can discuss it via QQ3155 91156
The raw material is oily； It may be tar or washing oil
Tar and coal powder are both possible.
