In the method proposed by Shehata et al.  for determination of iron in crude oil, 5 g of oil sample was used. These authors studied the effect of varying ratio of sulfuric acid to oil and. Chlorine determination in crude oil is currently performed according to ASTM standard method D using potentiometric titration. In this method, crude oil is dissolved in xylene and sequentially extracted with alcohol, acetone, and water in an electrically heated extraction apparatus.
Basic sediment and water (BS&W) is a both a technical specification of certain impurities in crude oil and the method for measuring it. When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation. The particulate matter is known as sediment or mud. The water content can vary greatly from field to field, and may be.

Determination of Water and/or Sediment in Crude Oil by the Centrifuge Method (Field Procedure) 1 Scope This section describes the field centrifuge method for determining both water and sediment or sediment only in crude determination of water in crude oil book. This method may not always produce the most accurate results, but it is considered the most practical.
The measurement of the amount of water in oils is of significant economic importance to the industrial community, particularly to the electric power and crude oil industries. The amount of water in transformer oils is critical to their normal function and the amount of water in crude oils affects the cost of the crude oil at the well head, the pipeline, and the by: The determination of water content in crude oil is important for oil transportation, refining, and trade.
However, the sensitivity and accuracy of the conventional azeotropic distillation (AD) method are inadequate. Karl Fischer titration methods may give false high results because of the reducing sulfur compounds in crude oil.
The present study developed an azeotropic distillation Karl Author: Zhilong Zhen, Haifeng Wang, Yuanming Yue, Dongmei Li, Xiaoping Song, Jia Li. Oil-in-water emulsions were used for crude oil sample preparation. Nitric acid was added to the emulsion only for the determination of total Ni and V concentrations.
This test method covers the determination of water in crude oil by distillation. This standard does not purport to address all of the safety concerns, if any, associated with its use.
It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica. The standard test methods for water content of crude oil samples by coulometric Karl Fischer titration, stipulate that the Karl Fischer anode reagent must be mixed in a or ratio with xylene to improve sample miscibility and reduce waxy deposits and asphaltines from dropping out thereby causing problems with the generator electrode.
However this modification to the reagent, and. WATER DETERMINATION IN CRUDE OIL KEITH LAWSON, LISA MYERS & KATHY SWALLOWS October THE MEASUREMENT OF WATER IN CRUDE OIL 2 •An improved technique for measuring the water content of crude oil •Obtaining ASTM/API approval for the method I.

37, No. 10, pp. Theoretically, all of the sediment and water determination methods are valid for crude oils containing from 0 % to % by volume sediment and water; the range of application is specified within the scope of each method.
The round robins for all methods were conducted on relatively dry oil. All precision and bias statements included in the methods are based upon the round robin data. This International Standard specifies a coulometric Karl Fischer titration method for the direct determination of water in crude petroleum.
It covers the range 0, % (m/m) to 5,00 % (m/m) water in crude petroleum containing less than 0,05 % (m/m) but more than 0, % (m/m) of either mercaptan sulfur or sulfide ion sulfur or both.

Water determination of crude oil can only be carried out by means of the volumetric method. Tar residues (pitch) may cause disturbances in the coulometric cell through contamination of the generator electrode.
Toluene and chloroform are suitable solubilisers. Specific solvents for oils are available for one- and two component titration. direct determination of acetic acid and formic acid in diesel and oil-containing diesel mixtures.
Introduction Organic acids in crude oil, refined products, fuel, etc., are one of the biggest concerns of the oil, oil refining, and car manufacturing industries. As a result of their corrosive properties and the associated costs of corrosion, organic. Significance and Use A knowledge of the water content of crude oil is important in the refining, purchase, sale, or transfer of crude oils.
Interferences A number of substances and classes of compounds associated with condensation or oxidation-reduction reactions interfere in the determination of water by Karl Fischer. This guide covers a summary of the water and sediment determination methods from the API MPMS Chapter 10 for crude oils.
The purpose of this guide is to provide a quick reference to these methodologies such that the reader can make the appropriate decision regarding which method to use based on the associated benefits, uses, drawbacks and.
The presence of water and/or sediment in a crude petroleum measurement system will lead to uncertainty in the value of an observed crude petroleum density.
This method specifies techniques for sample handling, sub-sampling, and the determination of density using a glass hydrometer, and the measurement of water and sediment contents of crude. Water is perhaps the most harmful of all contaminants with the exception of solid particles.
While the presence of water is often overlooked as the primary root cause of machine problems, excess moisture contamination can lead to premature oil degradation, increased corrosion and increased wear.
Moisture, upon contaminating hydraulic and lubricating oils, has a degrading effect to both the.Metal determination in crude oil is carried out by using dry ashing, dilution in organic solvents (Annual Book of ASTM, Annual Book of ASTM ) or using micro-emulsions (Santella et al.,).Drug ashing is used for complete elimination of organic matter, before analytical.The Determination of water content in the custody transfer metering of crude oil: Conference papers, 24th FebruaryLondon on *FREE* shipping on qualifying offers.
