Often, due to compression dynamics in multi-staged vacuum-pressure systems there is a mismatch of capacities between the vacuum and compressor pumps (with vacuum pumps having a much larger nominal pumping speed than the compressors).
In this first case study, find out how Busch was able to identify an operational solution utilizing different control instrumentation, as well as design considerations including recycle lines and safety features to enable simple vacuum and pressure operation seamlessly. In the second case study, find out how dry vacuum technology improves operational reliability and eliminates oil costs in phenolic resin production.
