DEVELOPMENT OF MODELS OF ATMOSPHERIC AND RECTIFICATION COLUMNS IN PRIMARY OIL REFINING

Abstract

At present, effective scientific methods and modern tools, in particular mathematical models and computer technologies, are required to obtain the necessary and high-quality petroleum products and ensure environmental safety in the processes of primary oil refining. In this regard, the goal and objectives of this work are to create control models that allow controlling the operating modes of the main columns of the atmospheric unit based on available statistical data, experimental, regression methods and the MATLAB system on a computer. Based on the data obtained by experimental-statistical methods and the method of sequential connection of regressors, the structure of the rectification models and atmospheric columns of the atmospheric block was determined. Unknown parameters of the structured models were obtained and identified using the Curve Fitting Tool of the MATLAB system.
