Analysis of non-linear processes in the primary processing unit and calculation of gasoline fraction properties
M.M. AsadovThe paper analyzes the operation of atmospheric block of electric demineralization unit in the primary oil processing (ELOU-AVT-6). For the linear processes a programming model has been selected. A calculation algorythm of the block’s optimum operation modes has been developed. The processes proceeding in the atmospheric block of the unit were reviewed as non-linear tasks. For solution of non-linear task were used a gradient and optimization methods. For selection of motion step and limitation conditions in the gradient method were used the experimental data on the gasoline fraction. A mathematical model and control algorythm have been developed. The calculation input parameters were generated from the experiment. Considering the limitations for the gasoline fraction yield, the optimum value in 34.67 % has been specified. The initial boiling temperatures for gasoline fractions have been defined in the laboratory conditions. According to the technical conditions, the boiling point of gasoline fraction should be equal to 40-60 °С, the value obtained from the calculation-experimental data is 70 °С. Moreover, the fractions boiling temperature should be end in the inetrval of 180-190 oC, from the calculation- experimental data it is 180 oC.
