Some personal opinions on the localization of S-Zorb filter device

Thread Content

because* * In response to the improvement of gasoline and diesel standards, the S-Zorb (adsorption desulfurization) device has been introduced. The filtration device has become a key to the complete localization of its equipment. I would like to express some personal opinions on its localization: First, the production of its filter elements must be at or close to imported products to ensure its reliability. It is not easy to have excessive requirements. Second, the length of the main reactor, fluidized bed reactor filter, and filter element should be short. On the one hand, this is beneficial to regeneration. On the other hand, it extends the distance from the reactor to the filter element after diameter expansion, which is beneficial to the settlement of the catalyst and reduces the filtration volume. Third, increasing the filter area and extending the backflush time is beneficial to protecting the backflush valve. Based on the principle of first catching up and then surpassing, after reaching the level of imported products, the design and manufacturing capabilities should be strengthened to complete the surpass. First, the filter element is improved and a composite layer filter element is used to achieve surface filtration. The significance is brief. Second, the design of the reactor and filter is completed together to realize the organic coupling of the two equipment.
