Dividing Wall Column as Energy Saving Retrofit Technology

摘要: The present paper shows that existing two- or three-column sequences could be transformed in a cost-effective way into dividing wall column (DWC) to allow for energy saving equivalent achievable new designs. This makes DWC an interesting retrofit option process industries willing achieve substantial reduction requirement and car- bon dioxide emissions plants. Additional benefit is reflected the potential increasing substantially capacity of units most sustainable way.
