It is understood that the asphaltene contained in heavy oil is a heavy hydrocarbon fuel mixture. Due to the different nature of the solvent used, it is easy to cause precipitation, thereby blocking pipes, filters, combustion injectors and the like. Therefore, production stations, refineries, and heavy oil users need to constantly test the stability of heavy oil in order to improve production processes and improve production efficiency. In addition, the heavy oil stability rapid analyzer can perform the emulsification operation of the water-in-oil emulsion during the oil recovery process, test the stability of the drilling fluid and monitor and test the stability or instability of the dispersion system.
