As the variety and sources of crude oil in China continue to diversify, obtaining timely evaluation data of crude oil becomes essential for market transactions and production operations. For refineries, the use of various crude oils and blends is common due to market transactions and changes in raw materials. Additionally, during crude oil distillation and pipeline transportation, switching crude oils causes natural mixing in the pipelines. The inability to promptly monitor crude oil properties makes efficient operation of crude oil distillation units challenging with frequent changes and mixing. During significant fluctuations in crude oil properties, operators usually rely on temperature, pressure, and experience to make adjustment, leaving a safety margin during crude oil switching, reducing processing capacity, decreasing product yields, and increasing operating costs. Therefore, the development of rapid crude oil property determination methods is demanded by market and production developments.
