It depends on which sections are involved. In power plants, the process of desulfurization places the highest demands on valves in those areas where limestone slurry is used for neutralizing acidic gases, as this environment is extremely corrosive and abrasive, thus requiring valves with high quality standards. Ceramic-lined ball valves are now widely used. http://ljbasd.blog.163.com
What desulfurization process do you use? Generally, desulfurization processes are prone to corrosion, wear, and clogging, which is why butterfly valves are widely used
Butterfly valves are widely used in desulfurization processes, and the choice of valve material depends on the process stage, specifically on the chloride content. When limestone slurry is used as the medium, its chloride content is relatively high; if this value exceeds 60,000, valve materials of grade 1 must be used. For 4529 duplex steel, the cost is around 40,000; in such cases, 2507 duplex steel is used, that is, the valve plates of ordinary valves are made of duplex steel. The valve seat selection depends on acidity and alkalinity, as well as the degree of resistance to corrosion. If durability is taken into account, there is also linear flow rate. Use a V-type ceramic ball valve. It also depends on the process and the medium, with the medium being the main factor.
If you need material selection information in this area, I have specific details on butterfly valve materials available; please provide your contact information and I can send them to you.
