Technological modeling of the atmospheric distillation unit of stable gas condensate

The article considers the development of a digital model of the process of atmospheric distillation of stable gas condensate. The primary oil refining unit is the core of a single technological scheme of oil and gas processing enterprises. Changing the operating mode of such a unit affects the quality and quantity of manufactured products, as well as the operation of secondary oil refining units. The paper considers the main problems of increasing the capacity of the unit in the absence of the necessary technical re-equipment to maintain the design indicators of product quality. The developed digital model can be used to solve problems of optimizing process performance and production conditions, determining the possibility of energy saving, calculating the economic potential for obtaining additional profit, when designing similar processes. The object of modeling is an operating stable gas condensate refining unit with a capacity of 4 million tons per year of one of the enterprises operating in the territory of the Russian Federation. During the modeling, the process flow chart is described, material and heat balances, and quality indicators of the process products are obtained. The adequacy criterion for assessing the performance of the digital model is a comparison of the indicators of the obtained products with real data from sample analyzes and material balances, subject to similar process parameters.
