Potential-digging revamping including increasing unit capacity, decreasing energy consumption, etc., could promote the unit competitiveness observably:
1. Reducing energy consumption and saving cost by improving separation technology. For instance, Azeotropic distillation is applied in ADP process instead of traditional distillation, which can increase capacity while decreasing energy consumption by 30~50%. For another example, extractive distillation is adopted in AED-BTX process instead of traditional technology, which can increase capacity while decreasing energy consumption by 30%.
2. Optimizing the process and reducing energy consumption by strict process simulation.
3. Enhance efficiency and capability by applying dividing-wall column technology, thermal coupling technology, heat pump technology and other technology.
4. In revamping cases, the most advanced technology of column internals can be applied to enhancing capacity and increasing separation efficiency. Generally, capacity can be increased by more than 30% without changing column shell size and diameter.
5. Calculating peripheral equipment based on strict material balance and heat balance.
