Water content testing for crude oil, petroleum, fuels, chemicals, and other refined petroleum products. Free water is when the water content in oil visibly separates. For the extracting medium, we use solvent CM. The simplest way to determine the presence of water in oil is to use the Visual Crackle test. Quantifying the Amount of Water: Karl Fischer Water Test If a crackle test is positive, further testing is needed in the form of the Karl Fischer Water Test.
Water contamination causes multiple problems in lubricating oils, although corrosion is always directly associated with water ingress.Whatever the equipment, water can displace the oil at contacting surfaces, thinning the lubrication film and activating surfaces which may themselves act as catalysts for degradation of the oil. Water can exist in three states: dissolved, emulsified and free. The measure water content in an insulating oil we use Karl Fisher Titration as basic technique. It's used in the circustances of explosion-proof,such as sites concerning petrochemical waste water continually,build up alarm reporting for over-limitation and control the volume of discharge waste water.
