Kister Distillation Symposium 2017: Optimum Design and Operation in Refinery Distillation

Refinery vacuum units include a deentrainment, or wash zone, for removal of heavy material from desired products. Wash zone reliability problems often shut vacuum units down, causing significant losses. The review of wash zone operations cover;
- Operating objectives
- Fractionating versus deentraining wash zones
- Wash zone terminology
- Operating configurations
- Hot-wash versus cold-wash
- Wash oil distributors
- Conventional configurations
- Spray chambers
- Multiple stage wash systems
- Recycle wash systems
- Wash zone modeling and reliability
Elements of case studies from multiple units are included to illustrate key points.
