Issues with the metal sintered filter elements in the reforming catalyst dust collector

Let’s see if this expert has a suitable filter element~~@yitaikeji2007

Do you also use the IFP process, and are the filters from Zhaoqing? Which unit are you from?

Metal sintered filter element? You can visit our company’s website at http://shaoguanberae.cn.china.cn/. Mr. Chen’s phone number is 13826340878

Is your filtration system of the end-cap type or cross-flow type? The equipment can be modified to enable fully automatic control, and I can handle this. For more details, please contact me at 2196940349 on QQ

For the ultra-precise removal of dust from high-temperature air streams, metal-sintered filter elements represent one of the few available options. On the one hand, ultra-precise removal of dust from high-temperature air streams (with a removal accuracy of 3N level for particles with an equivalent diameter of less than 1 micron) requires the use of filter elements; on the other hand, in high-temperature air stream conditions, only metal material filter elements can withstand such high temperatures. However, the reason why precision filter elements are good at precise removal is also that it limits them to handling only delicate tasks. The vast majority of the dust contained in the air flow must be removed in advance, leaving only a very small amount of fine dust that can then be removed by the precision filter element. Otherwise, both rough and fine tasks are carried out by the precision filter element, which inevitably leads to overloading of the element, a short operating cycle, frequent regeneration, a short service life, heavy operation and maintenance requirements, and high operating costs. For the gas-solid separator responsible for dry removal of the majority of dust in high-temperature gas streams, a multi-factor cyclone mother-son separator is typically used. It is said that the multi-factor cyclone mother-son separator developed by a specialized separation technology company is designed specifically for the capture and recovery of catalysts in high-temperature fluidized bed systems, as well as for the removal of dust and tar from the hot raw gas produced in coal gasification processes. It utilizes dynamic separation techniques, offering high separation efficiency and great operational flexibility. Its continuous operation life can reach 20 years; it does not require regeneration, has no spare parts needed, is easy to maintain, and incurs low operating costs. It performs excellently in upgrading traditional process equipment for the capture and recovery of heavy oil hydrocracking catalysts, as well as for the separation of dust and liquid droplets in coal gasification units, both domestically and internationally.

The choice of separation method depends mainly on the solid content level. For metal powder sintered filters, they are suitable for gases with a solid content of less than 1%. For higher levels of solid content, it’s better to use the method mentioned above first, and then add another filter made of metal powder sintered filters to handle any remaining impurities. This approach yields the best results while also keeping costs low.

The catalyst reforming dust collector has been manufactured domestically. In fact, it does not require ultra-high temperatures or corrosion resistance; using dust collection bags is sufficient to achieve good results. Metal filters are expensive and difficult to clean, so it is recommended to use dust collection bags instead.
