How is the acid-to-hydrocarbon ratio controlled in the DuPont alkylation process?
Thread Content
The alkylation reaction requires control of the acid-to-hydrocarbon ratio. In the LUMMUS process, this ratio can be controlled using acid circulation pumps and hydrocarbon circulation pumps; however, the DuPont process does not have such pumps. So how is the acid-to-hydrocarbon ratio controlled in that process?
Controlled by the opening degree of the acid reduction valve
Thank you. Can the acid-to-hydrocarbon ratio be controlled accurately by adjusting the opening degree of the acid reduction valve? According to some sources, the acid reduction valve should be fully opened to lower the acid level in the sedimentation tank.
