Acceptable levels of dissolved moisture typically range from 50-300 ppm (or 0.0050% – 0.0300… acids and phenols. In two-component KF, the titrant contains only an alcoholic solution of iodine, while the solvent contains the other ingredients needed for the reaction. However, if the temperature of the oil is extremely high, for instance in internal combustion engines, the increased temperature will cause the water vapor to come out of the solution. This innovative KF technique is incorporated in ASTM D6304 (Method B) and is applicable to nearly all oil-based samples. In the majority of these incidents there is often no emergency oil spill response plan and/or equipment available. The extract is then dried and purified before a small amount of the extract is injected into a GC instrument. In industrial oils having robust water separation characteristics, standard methods are not suitable to determine water contamination. The air’s relative humidity is a well-known concept, especially in warm climates during the summer months. Due to the use of volatile chemicals and the sample preparation required, KF titration is often performed in labs and cannot be easily used at the site of the instrument being analyzed. Oil in water is a method defined parameter, thus different methods will produce different results. Water content test methods include accepted industry standards such as ASTM, ISO, EN, IP and others. Overall, mineral oil and hydrocarbons are List 1 substances and therefore discharge of these to the control water is strictly regulated. An example of a GC-FID-based reference method is the ISO 9377-2. In general, the pH value needs to be lowered to less than two. Dr. Yang has also initiated and led several joint industry projects, and has presented and chaired many produced water-related events. These techniques depend on a number of factors, such as personnel training, budget, the data precision needed, etc. Dispersed oils are those found in water in the form of small droplets. WATER CONTENT Test Method IEC 814 Water, in minute quantities, is harmful in power equipment because it is attracted to the places of greatest electrical stress and this is where it is the most dangerous. Candy - In my experience, the oil manufacturer does not specify the allowable water content on their applicable Product Data Sheet. After a while, the manometer fixed to the reaction vessel will read the internal pressure, and based on the relative mix of diluent and oil, the pressure reading is changed to a % water reading. This can cause uncontrolled hydraulic movement or brakes failure. There are primarily two types of tests being used in … Privacy Policy |Copyright Bay Publishing. If it has degraded the viscosity down to 113 from 150, you need to change the oil, find how the water is getting in and address that issue. Examples include BTEX (Benzene Toluene, Ethyl-benzene and Xylene). Dissolved water is similar to humidity and cannot be seen in oil. to separate water efficiently above saturation limits of. For surface water discharges, which refer to those that are discharged to groundwater, sea, river or lake, in terms of mineral oil and hydrocarbons contained in the discharge water, the discharge limit depends on the potential local environmental impact. Pollution of oil can come from many different sources. AMETEK Spectro Scientific. This is because the water may have damaged the oil additives.
