Abstract
Basic sediment and water content of crude oil flowing through a pipeline is measured by removing a representative sample of the crude oil, heating the sample, and centrifuging the sample to separate the water from the oil. The vapor pressure in the centrifuge is controlled to prevent the escape of any water which has been vaporized by the heating step. The water fraction is passed to a condenser to condense whatever water was vaporized during the heating. Following the condensing step, the water flows into a measuring vessel and is measured.
