[0002] The heavy oil water content experiment is a commonly used experimental method in petroleum chemistry, mainly used to detect the water content in samples such as crude oil and heavy fuel. Through this experiment, the purity and composition of the sample can be understood, providing a reference for subsequent processing and utilization. Experimental principle: In the heavy oil water content experiment, the heavy oil sample is first mixed evenly with a certain amount of anhydrous sodium sulfate, and then heated to a constant temperature. Under high temperature conditions, anhydrous sodium sulfate absorbs the water in the sample to form a high-viscosity gel-like substance. When the mixture is cooled to room temperature, the excess water is adsorbed on the surface of anhydrous sodium sulfate, causing the anhydrous sodium sulfate to return to its original powder state. At this point, the experimenter can calculate the water content in the sample by weighing the weight difference of anhydrous sodium sulfate before and after the sample.
[0003] In the experiment of analyzing the water content of heavy oil, a certain volume of water-carrying agent toluene needs to be added. After the experiment, the remaining oil after analysis is discarded together with toluene. Toluene is a chemical that is easy to make drugs, and it has certain pollution to the environment and is very harmful to the human body. Utility Model Content
