One of the key issues related to unconventional gas exploration and production, that must be addressed, is the flowback water, and subsequent produced water. Water content in ppm; Viscosity; Acidity level (TAN) If the oil additive content is of interest, a Spectral Analysis should be included. If there is visible water present in the sample, evident by a cloudy or milky appearance or if it has settled to the bottom of the sample bottle, then there is a strong chance of water will show in the lab report. The procedure involves adding the oil sample to the solvent present in the evaporation chamber where it dissolves in the solvent, and in the process forms a binary azeotrope between the solvent and the sample's water content. Methods for Measuring Water in Lubrication Oils. The oil’s water content can be precisely measured by quantifying the amount of iodine required to titrate the oil sample. Separation efficiency will depend on many factors, e.g. Thanks to all. Class 1 separators, which are designed to achieve a concentration of less than 5 mg/l of oil under standard test conditions, should be used when it is required to remove very small droplets. Also some of these constituents may be present but might not contribute to the measured oil in water. Crackle Test is cost- effective, fast and easy, and can be performed on-site. Results correlating within 20% to KF can be obtained using best practice sampling methods. Calcium hydride test kits are integrated with a number of components such as manometer, pressure vessel, syringes, diluents, safety glasses, gloves, pre-measured calcium hydride packets, sealing rings, and sometimes are even integrated with a magnetic stirring plate. However, alcohols cannot be completely removed from KF reagents, because the presence of alcohol is required by the mechanism of the KF reaction. These are briefly described below. These fumes could potentially indicate the system has water ingress, which should be confirmed by submitting an oil sample. However, if liquid water is present in the oil, the heat will convert this water into vapor, producing bubbles that can be seen in the drop of oil. "Methods for Measuring Water in Lubrication Oils". To get a good oil in water result, in addition to having a good analysis method, sampling and sample handling is equally important, as measurement can only produce a result as good as the sample can provide. In coulometry, the quantity of iodine generated corresponding to the amount of water present is calculated by the titrator on the basis of current (mA) and time (sec). Replies and comments they make will be collapsed/hidden by default. What is the acceptable level of water content and viscosity for this type of compressor oil? That is, while the iodine in the Karl Fischer reagent is reacting with water, there is no free iodine present in the titration cell, and a high voltage is required to maintain the set polarization current at the double platinum pin indicator electrode. By continuing to browse this site you agree to our use of cookies. This moisture is derived from ambient air humidity slowly interacting with the lubricant oil overtime. CEO of Bcomp, Christian Fischer, talks to AZoM about an important involvement with Formula One's McLaren. The subsequent oxidation of the alkylsulfite salt to an alkylsulfate salt by iodine consumes water in a 1:1 ratio to iodine, thus making the quantification of water possible. It may contain aliphatic, aromatic hydrocarbons and other organics, e.g. Whilst treatment technologies are available, they are not always there at the right place and right time. ©2020 Association of Asset Management Professionals Inc. Sampling plays a key role in this variation, and the homogenizer forms a central component of the technique. If the level of water is higher, the oil sample must be diluted using a diluent of known amount. An Article by Dr Ming Yang. For regulatory compliance monitoring, samples may have to be taken at specified locations, while for process control and optimisation, this is not an issue. Water content. If the system is using a synthetic polyglycol (PAG) oil, then these products have a natural affinity for water and able to absorb water vapour from the air; such fluids are termed hygroscopic in chemist lingo. Three types of RH sensors are available, namely thermal conductivity, resistive and capacitive. h�bbd```b``>"��H�@�~,�I�,�A$kX|!X��^ f7��I@��=̾"E$A� �dx6�D��m���ٖ`�,RfۃL��f�t���e`bd`6��qؒ�yo ��� The most frequent causes of oil pollution are spillage during delivery, leakage from poorly maintained or damaged tanks, lack of oil separators, waste oil disposal into drainage systems, waste oil dumped onto or into the ground, and in some cases waste oil burnt in the open. He was one of two authors who originally drafted the UK guidance notes on sampling and analysis of produced water and other hydrocarbon discharges. In order to prevent equipment failure and the resultant downtime, instrument should be tracked continuously for water contamination. In such types of oils, the additive formulations are designed in such a way that water is efficiently separated above the saturation limits of 50 to 250ppm water. When analyzing water contamination in turbine oils, the FluidScan serves as a powerful and reliable technique and provides instant alerts when there is severe contamination of water. Karl Fischer (KF) coulometric titration (ASTM D6304) is a well-established technique, which is used for detecting the presence of water in oil. It can result in harm to the aquatic environment, water treatment plants and also generate bad publicity. In Coulometric Karl Fischer, the iodine needed by the KF reaction is not present in the KF reagent, but is instead generated electrochemically in situ from iodide at the anode of the generator electrode, a component of the coulometric titration cell (Figure 2).
