Abstract:

With the capacity expansion of a propylene oxide/styrene monomer (PO/SM) plant, the existing equipment layout of MPK hydrogenation reaction framework can no longer meet the production demands. Focusing on the trickle-bed reactor of the MPK hydrogenation unit and following the principles of gravity flow priority, grouped and symmetric equipment layout, balanced operability and maintainability, and economic-safety integration, the problems in the original layout such as uneven pipeline conditions and insufficient operating space were solved by optimizing equipment elevation differences, implementing symmetric piping, and consolidating operation platforms. The key points to be considered in the equipment layout of framework, the setting of operation platforms, and the layout of important pipelines are introduced. A reasonable layout of the framework plays a crucial role in ensuring the safety and stability of the plant, reducing the energy consumption and investment, and guaranteeing the catalyst reduction and hydrogenation performance. This provides practical engineering reference for the design of similar trickle-bed hydrogenation reactor frameworks.

Key words: MPK hydrogenation reaction framework, equipment layout, piping layout
