Water- In- Crude Detecting Devices Their Applications To Royalty Custody Transfer Measurements

摘要

The paper talks about the technology and operations of the various water-in-crude detecting devices and their possible application to royalty and custody transfer measurements of crude and hydrocarbon products. It highlights the operations, current research, field test studies and viability of such devices for better precision and higher accuracy in the measurement of volumetric through puts for exports and domestic consumption. Through finer precision and higher accuracy, proper accountability can be achieved and tremendous cost savings realized. The technology and operations of the various water-in-crude detecting devices is one of the many current technologies being evaluated today by major corporations and private instrumentation manufacturing companies in the hydrocarbon industry. The application to royalty and custody transfer measurements of crude and hydrocarbon products, of the water-in- crude detecting devices is still in its research and testing phase. Unlike process conditions, custody transfer criteria have more stringent conditions to comply with. Process conditions allow possible accuracy tolerances between 2-5% and the process data is used for internal material balance, leak detection and loss control. Custody accuracy tolerances, however need to be between 0.25-0.50% margins. This is because financial and commodity exchange takes place and the point of custody, where actual cash is either gained or lost.
