What material is suitable for reactors used in sulfur trioxide sulfonation processes?
Thread Content
There is an organic compound that is sulfated using sulfur trioxide, and water is produced in the process. Upon calculation, the excess sulfur trioxide along with the sulfuric acid produced is equivalent to about 140% sulfuric acid fuming. The reaction temperature is below 20°C. The reaction is cooled using chilled brine, and enamel-lined reactors are used for pilot-scale testing; however, their cooling surface area is too small, which affects the feeding rate of sulfur trioxide. Now, consider adding coils inside the reactor. What materials would be suitable for choosing for both the reactor and the coils? ? ? Please, experts, share your suggestions. . . .
It is recommended to replace the stirrer; our company’s new enamel stirrers are suggested, offering an efficiency that is 1.5 to 2 times higher than that of conventional frame or anchor-type stirrers.
Judging from the poster’s description, a tubular reactor seems to be better than a reaction kettle! (Personal suggestion) If the OP is interested, we can chat about it! :lol
