Significance and Use

The water and sediment content of crude oil is significant because it can cause corrosion of equipment and problems in processing. A determination of water and sediment content is required to measure accurately net volumes of actual oil in sales, taxation, exchanges, and custody transfers.

Scope

1.1 This test method describes the laboratory determination of water and sediment in crude oils by means of the centrifuge procedure. This centrifuge method for determining water and sediment in crude oils is not entirely satisfactory. The amount of water detected is almost always lower than the actual water content. When a highly accurate value is required, the revised procedures for water by distillation, Test Method D 4006 (API MPMS Chapter 10.2) (), and sediment by extraction, Test Method D 473 (API MPMS Chapter 10.1), shall be used. Note 1Test Method D 4006 (API MPMS Chapter 10.2) has been determined to be the preferred and most accurate method for the determination of water.
