DETERMINATION OF PROPERTIES OF OIL

摘要

A method of controlling a separation of a component in crude oil, e.g. downstream of a well head, in which the oil is analysed, e.g. by near infra red (NIR) spectroscopy, at or before a pipeline between the analyser and separator especially a line at least 10 km long and the results used to optimise the separation. NIR spectroscopy is also used to determine a property, e.g. composition of a crude oil, in particular its content of naphtha, gas oil and/or fuel oil.
