The diesel tank became cloudy after transfer; what could be the reason?
Thread Content
After performing the tank transfer operation using a small pump from the dehydration outlet, the oil became cloudy. The weather has been cooler these days (the temperature difference isn’t very large; in the south, the temperature remains above 20 degrees Celsius). Is this due to the weather or something else?
Has it mixed in with the water and emulsified? Or the wax contained inside crystallizes at low temperatures.
Based on what the poster has described, what was said above makes sense – the water remaining at the bottom of the medium mixes with diesel to form an emulsified oil.
There are many reasons: alkali, moisture, rust, impurities, and so on.
It depends on what kind of diesel you have. When water is mixed into oil, emulsification occurs. With biodiesel, it is likely that wax crystals form as the temperature drops.
Water, rust residues, and other sediments will settle at the bottom of the oil tank; mixing the contents of the tank will certainly result in turbidity, so one can only wait and monitor the settlement process；
When pouring from the dehydration port, some water and sediment will be present, right? Why pour from the dehydration port? Is it to clean the oil at the bottom of the tank?
It is estimated that transfer occurred via the connection at the dehydration outlet; there was water at the bottom of the tank, and the water at the bottom mixed with the diesel, resulting in emulsification
Reason for analysis 1: Water-containing emulsification; even trace amounts of water can cause the oil to lose its clarity； 2. The proportion of the anticoagulant is excessive, or the anticoagulant used has unstable properties. It happened in our company before as well; we still used high-viscosity oil for pouring, and we were unable to determine the reason for this. Once the oil became clearer, its color intensity increased and its freezing point rose as well
Everything said above is correct; it is recommended that the original poster conduct sampling analysis to determine what the problem is – whether it’s related to the water, the mechanical components, or something else.
