After experiencing some problems with Coriolis meters from another supplier, Gale Beutler, Plant Maintenance Foreman at BP Sarnia’s Fractionation Plant, had just about given up on Coriolis technology. However, an E+H Flow Seminar at Lambton College was instrumental in changing his mind. The presentation, while not bashing the competition, stressed the advantages of the E+H Promass Coriolis meter in providing a stable signal unaffected by vibration, and the ability to handle fluctuating flows in both directions. Gale decided to give the technology another chance. BP’s Fractionation Plant in Sarnia, Ontario produces some 130,000 barrels per day of petroleum gas product, the majority of which is propane. Excess propane is stored in seven caverns capable of holding 5 million barrels, 2000’ underground. From the caverns it must be available for immediate loading into rail cars, trucks or sending to pipelines on demand. Whereas overfill of the caverns is dangerous, underfilling could mean inability to meet unexpected demands. So for inventory control purposes, a highly accurate bi-directional flow measurement is necessary. Due to fluctuating flow orifice plates and turbine meters could not provide the required accuracy, but the application seemed idea for a Coriolis meter. Originally BP purchased three E+H Promass 63 coriolis meters and were so impressed with the increased accuracy that they have since purchased two Promass 83’s to upgrade another two of the caverns, and plan to eventually upgrade all seven.
