【Q&A Question 028】May 18, 2016: How to check whether the circulating water contains oil? The answer key will be available after responding; scoring is based on answering the key points. Inspect the drain samples at the outlets of each oil cooler, let them stand, and check whether oil is present; they can also be sent for laboratory analysis.
Sampling analysis. We need to install online monitoring facilities here.
Open the drain at the lowest point of the circulating water return pipeline; if there are visible oil droplets or if a combustible gas detector detects combustible gases, it indicates that the system contains oil
Just check for any oil stains or separation; generally, if the amount is small, it won’t be a big problem
The first step, which is to deal with the sludge pump, is certainly the top priority. We immediately identified the source of contamination, used an oil collector to remove the polluted oil from the surface of the circulation tank (an overflow method can also be used), added an oil dispersant to break up the polluted oil, then carried out extensive water replacement. After the oil was removed, a bactericide was added for treatment, and now the problem has been resolved. The above are just some of my simple methods. If any experts have better approaches, I would appreciate it if you could share them so that we can all improve together.
Oil is lighter than water; check whether there is any oil on the surface of the water
Isn’t oil generally less dense than water?
Inspect the samples taken from the outlet drains of each oil cooler; let them stand and check whether oil is present
