Consider novel CGC and front-end depropanizer system for olefins production
In the presented case study, an innovative design for an integrated CGC-DeC3 system introduces part of the heavier condensate from the early compression stages directly into the high-pressure (HP) depropanizer.
Enhance operation and reliability of dividing-wall columns
Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux..
Optimize vacuum ejector operations
Vacuum distillation unit (VDU) designs generally involve jet ejectors due to their low capital and operating expenses, high reliability, durability and simplicity. Once the ejector is installed and co..
Neste Oil to upgrade heaters at Porvoo refinery
As part of the investment, fired heaters at the refinery's crude distillation unit will be replaced with new-generation heaters, which Neste says will help ensure more consistent, incident-free operations at the site and yield annual energy savings worth an estimated €4 million.
