EFFECTS OF PETROLEUM PROPERTIES ON PIPELINE MEASUREMENT Paper #2130

摘要

Measurement of liquid hydrocarbons in pipelines is done on a standard volume basis or by mass.These dynamic measurement points typically are custody transfer and act as the"cash register"measurements between the two parties involved in the transactions.This is the primary reason why measurement accuracy is critical.Other areas of consideration being product accountability and a"one time"dynamic measurement point.The volume or mass measurements must account for the entire liquid product received or delivered in order to track and determine if product is being lost or gained.Several fluid properties including pressure,temperature,viscosity,and density can change the accuracy of this measurement and knowing how they impact the measurement is crucial to maintaining integrity.This paper focuses on dynamic measurement(measurement by metering) and discusses several fluid property effects on measured results involving the common types of metering technologies used today.
