New Control Method For Fixed Speed Compressors With Side Stream

Case StudyProblem statement: Operability issues were experienced on flash gas back-to-back compressors with lower molecular weight side stream, driven by fixed speed electric motor: • Failed attempts of start-up/loading • During normal operation compressors went off-line due to process upset (e.g. inlet flow decrease) • Unable to operate parallel trains simultaneously. Consequent loss of production
