Type of article: Periodical article

Summary

THE AUTHOR DESCRIBES MICROPROCESSOR-BASED MONITORING EQUIPMENT OF A SUFFICIENTLY RUGGED NATURE TO BE INSTALLED PERMANENTLY IN AN INDUSTRIAL AMMONIA 2-STAGE SYSTEM USING A RECIPROCATING COMPRESSOR. PRESSURE MEASUREMENTS ARE BY STRAIN GAUGES USING PRESSURE TRANSDUCERS, INCLUDING A DIFFERENTIAL PRESSURE TRANSDUCER ARRANGEMENT WITH AN ORIFICE PLATE FOR FLOW MEASUREMENT. THIS IS PLACED DOWNSTREAM FROM AN OIL SEPARATOR IN THE LOW PRESSURE DISCHARGE LINE. AN ANALYSIS PACKAGE CALCULATES ENTHALPIES, ENTROPIES AND SPECIFIC VOLUMES, ALLOWING DEDICATED SYSTEM CALCULATIONS TO BE MADE AUTOMATICALLY OF CARNOT, CYCLE THEORETICAL, AND ACTUAL SYSTEM COP, AND VOLUMETRIC EFFICIENCIES FOR BOTH STAGES. THESE ARE MONITORED CONTINUOUSLY SO THAT SYSTEM DETERIORATION CAN BE SEEN EASILY. THE WHOLE EQUIPMENT PACKAGE IS RELATIVELY INEXPENSIVE AND CAN BE INSTALLED ON AN EXISTING SYSTEM. D.W.H.
