Choice and operation of vapour compressors in chemical production plant . The use of vapour compressors for evaporation, distillation processes and also for more complex processes has increased greatly due to the large increases in energy costs in the past. Generally, high speed radial compressors are used for these applications. Recommended operating ranges, investment costs as well as efficiencies at different compression ratios are explained, based on experience gained in technical application and manufacturers information. The example of combining a separation column and an evaporation step shows that not only a saving of energy, but also a significant reduction of waste water generation is achieved. The control strategy for a process having several recycle flow streams is explained. Based on operating experience, recommendations for field monitoring of the compressor are given.
