Key design considerations for vacuum process condensers

The crude oil refining and petrochemical industries make extensive use of condensers that operate under vacuum (i.e., below atmospheric pressure). Distillation is the most common process using these condensers, either as a process precondenser ahead of an ejector system, or as an intercondenser within an ejector system.

The crude oil refining and petrochemical industries make extensive use of condensers that operate under vacuum (i.e., below atmospheric pressure). Distillation is the most common process using these condensers, either as a process precondenser ahead of an ejector system, or as an intercondenser within an ejector system. Proper operation of a vacuum condenser is essential for distillation process throughput and/or fractionation. When these condensers perform poorly, it can become a major issue for the refiner or petrochemical plant because profit loss is significant when distillation product quality is inferior, or when throughput is scaled down to maintain process quality.
