Material selection and type determination for reaction vessels – Advantages and disadvantages of enamel-lined reaction vessels
Thread Content
I have worked at two manufacturing companies as an assistant engineer. One company produces pesticide intermediates such as anisole and trichloroacetyl chloride, while the other manufactures additives for household cleaning products; in both cases, enamel-lined reactors are used, presumably because of their corrosion resistance. I would like to know whether enamel-lined or glass-lined reactors are cheaper than stainless steel reactors What are the advantages and disadvantages of enamel reaction kettles, and what should be noted during use?
Enameled reactors have excellent acid resistance but poor alkali resistance. Stainless steel reaction vessels are relatively expensive
Trichloroacetyl chloride may be obtained through chlorination reactions. In other words, hydrochloric acid is present during the process. The most cost-effective option for resisting hydrochloric acid is a glass-lined reactor. Others, such as household detergents, may be used for cleaning. Glass has the ability to stay clean. It also has antibacterial properties. Cosmetics should be necessary.
It’s more expensive than stainless steel. I work in the field of high-end enamel equipment and fluorinated lining equipment, as well as pipes and valves. Could you add me on WeChat? My number is 17715282753, thank you!
Firstly, in terms of cost, the expense of enamel reactors is lower than that of stainless steel reactors. As for resistance to acids and alkalis, enamel reactors do have good acid resistance, with hydrofluoric acid being an exception; they can also handle alkalis, but they are not resistant to strong alkaline corrosion.
As for strong bases, as long as you don’t boil a pot of sodium hydroxide, there’s no problem
