Ham petrol tuz arındırma işleminin saha doğrulanmış akış şeması simülasyonu ile iyileştirilmesi

When crude oil is extracted from reservoirs, it's common to find water, sediments, and mineral salts. The oil's high salinity is the primary factor contributing to corrosion in pipelines and equipment; it hinders the mass transfer process in the distillation unit's fractionator trays and diminishes the effectiveness of separation, necessitating additional equipment and power. Presently, prevailing requirements for desalted crude oil demand that salt concentrations be below 20 ppm. Thus, treatment in production oil fields is the first line of defense against the effects of salts. This study aims to improve crude oil desalting by using a verified flowsheet simulation with the most effective set of conditions for crude oil trains. We validated the simulation by comparing it with real field samples in three aspects: composition, dehydrator and desalter efficiency, and process parameters. The current operating parameters of the selected crude oil train are as follows: temperature, pressure, wash water flow rate, crude oil feed, and demulsifier dosage as 50 °C, 41.5 barg, 21 m3, 116834 bbl/day, and 29 ppm, respectively. We studied the factors that affect desalting crude oil using case studies by simulation models developed using a commercially available Aspen HYSYS flowsheet simulation software package. The results predicted that in terms of desalting performance, the best operating conditions for treating crude oil were (temperature = 80 °C, pressure = 14 barg, wash water flow = 16 m3, crude feed = 116834 bbl/day, and demulsifier dosage = 16 ppm). The results from the simulations showed that the usage of wash water and chemical demulsifier could be significantly reduced while maintaining the targeted crude oil quality: 24% and 45% reduction in wash water flowrate and demulsifier dosage, respectively. Ultimately, the simulated model indicated that the desalting process could significantly improve desalting performance to 3 ppm (pounds of salt per thousand barrels of crude oil), with a major economic impact related to saving chemical demulsifiers in the order of (0.004 $/bbl) of produced oil.
