METHOD FOR CONTROLLING THE OIL MIXING PROCESS Russian patent published in 2021 - IPC G05D11/02 

FIELD: pipelines.

SUBSTANCE: invention relates to the field of pipeline transport, namely to methods for controlling the process of mixing oil with various physical and chemical properties. The method for controlling the oil mixing process consists in measuring the mass fraction of sulfur and oil consumption on each transported stream, based on the data obtained, the quality of oil cargo flows is evaluated in the direction of the final delivery points based on the calculation of the quality stability values of each transported stream using the law of normal distribution of a random variable, and based on the assessment of the quality of oil cargo flows, oil flows are maneuvered. As a random variable, the value of the mass of unbalanced sulfur for the considered period of time is taken, expressed as a deviation of the mass of sulfur equal to the product of the mass fraction of sulfur per mass of oil from the weighted average value.

EFFECT: ensuring the required and stable quality of the supplied oil at the final points of delivery of the system of trunk oil pipelines, including many pipelines and oil mixing points, reducing fluctuations in the mass fraction of sulfur and maintain this indicator at a given level in the flow after mixing, increasing the reliability and efficiency of identifying objects of the system of trunk oil pipelines that affect the quality of oil at the final points of delivery.
