... for the Measurement of Highly Viscous Coker and Visbreaker FeedIn a typical complex refinery operation, VAC tower residue or other high viscosity liquid streams are fed into cokers and/ or visbreakers for further processing. The flow of these hot liquids (> 200°C) is traditionally measured with differential pressure devices (orifice or wedges) or vortex meters.Under the very severe process conditions, impulse line clogging and vortex shedders breakdown are frequent. High maintenance costs or even process shut down are the consequences. In a North American refinery, a differential pressure measurement was replaced without any process interruption with the non-intrusive WaveInjector®, eliminating daily maintenance tasks. Furthermore, the wide dynamic range of the FLUXUS turned out to be of additional advantage. Previously 4 orifice plates were necessary to cover the entire measuring range. Now a single instrument does the job.
