Abstract (English):
The purpose of this article is to describe the modelling of optimal operation mode and efficiency improvement of technological units of oil refineries using Aspen HYSYS. The paper considers methods of analyzing the operation of technological facilities in different modes by conducting tests at operating facilities and building mathematical models. Modern means of modelling of technological objects are presented. The mathematical model of rectification column in Aspen HYSYS environment is built, and the model is calibrated according to the data of the operating object. Using the built-in tool of column equipment hydraulic mode analysis, the operating mode of the contact devices of the apparatus was analyzed and the optimum hydraulic load on them was determined. The maximum increase of column productivity without loss of product quality was determined. Modelling and analysis of centrifugal pump efficiency is carried out. The description of optimization of technological mode of oil refining processes with the help of Advanced Process Control System is given. In the article some of the most effective modern methods and products for modelling, analysis and optimization of heat and mass exchange and hydromechanical processes are considered. The possibility of using Aspen Hysys software to analyze the hydraulic mode of column equipment to increase the productivity of the apparatus without losing the quality of the products obtained, as well as to analyze the operation of the centrifugal pump is analyzed. Also described is the technology of advanced TP control to stabilize the unit product quality parameters and maximize economic efficiency. The modelling method described in the article can be used to calculate the maximum column supply load, the basis for the effectiveness of the model is the calibration of its operation according to the data of real plants with an acceptable error of 5-7%.
