【Abstract】 Fully thermally-coupled distillation columns, as a new type of distillation forms, have been used abroad since 1990s. About 30 these columns are operation successfully, and their application has good prospects. They can achieve typically up to 30% of energy saving and reduce capital investment, compared with conventional consequences. In this article, fully thermally coupled distillation columns, including their configurations, energy saving principles, design and simulation technologies and application status in the process industries are reviewed.更多还原
