That type of equipment is good at filtering sulfur foam
Thread Content
Hello everyone. We are from a coking plant, and the sulfur foam after desulfurization goes directly into the sulfur melting tank. The operation of this tank is unstable and it tends to get clogged; therefore, we want to add an additional filtering stage before the sulfur melting tank. Some people say that a plate and frame filter press would be suitable, while others suggest a vacuum drum filter. May I ask those with more experience which filtering device would be more appropriate? What are their respective advantages? This post was last edited by adsl121 on 2009-4-11 00:38.]
Hello, owner. I work in the field of filter manufacturers. My clients are now starting to use vacuum filters in their sulfur filtration processes – they offer a high degree of automation, are simple to operate, and don’t come at high costs. Using a filter press is rather troublesome, while the cost of fully automatic systems is high. You can take a look, and you’re welcome to get in touch with us so we can discuss it together.

Our factory is currently using filter presses, but their performance is not very good; the working conditions on site are extremely poor. After visiting other factories, we are planning to switch to specialized centrifuges for desulfurization.
Yes, the filtering methods also need to take environmental pollution into account. It would be best to achieve automation without causing secondary pollution to the environment.
What those upstairs said makes some sense. In my opinion, there is an issue related to the processing capacity; if the daily processing volume is below 20 cubic meters, then plate and frame filters should be considered. The reason why the current systems do not perform well is mainly due to improper selection of filter fabrics and inadequate on-site management. For large processing volumes, consider a vacuum filter, as it offers a higher degree of automation. However, extra attention needs to be paid to the filter cloth and the separation mechanism, and the quality of the liquid after filtration must also be considered; if it is too turbid, it should not be returned to the system. After all, the vacuum level is limited. In most nitrogen fertilizer industries, I recommend using plate and frame filters. The operation intensity is not high, ensuring the quality of the clear liquid. It’s good for the system.
Plate and frame filter presses require frequent replacement of consumables, resulting in high operating costs and maintenance needs. Many manufacturers now use horizontal centrifuges, but these tend to get clogged easily. Vacuum rotary filter presses consume a lot of energy in operation. However, no matter what type of device is used, there are effective options available; the key lies in proper selection and on-site management. A internal fractionation type sulfur melting furnace would be a good choice; you can inquire around in the area near your factory to compare different options and determine which type of equipment is suitable for your plant
Special centrifuges for desulfurization perform well, especially with solutions that have a high foam concentration. However, proper design for sulfur recovery is necessary to avoid environmental pollution.
