Abstract

The invention relates to an optimal parameter determination method for researching the hot oil spraying and heating process of an oil storage tank, and the method comprises the steps: determining a decision variable according to factors affecting the hot oil spraying and heating effect of the oil storage tank in an actual production process; acquiring the actual measurement data of the hot oil spraying and heating process in the experiment storage tank under different parameters, taking the field cooperation angle, the uniformity, the heating efficiency and the average temperature rising speedas indexes for evaluating the heating effect, determining the weight of each index, and obtaining a target function through calculation; establishing a support vector machine model through the decision variable and the target function; generating an initial population with the size of M based on the support vector machine model, and optimizing the target function by adopting a genetic algorithm;taking the optimal variable as an experimental parameter to carry out an indoor simulation experiment to obtain a corresponding target function, and if an error between the target function and a support vector machine result exceeds a certain range, repeating iteration until the error is smaller than the certain range. According to the method, the optimal process parameters can be found, and the calculation precision is ensured to a great extent.

Description

Technical field: [0001] The invention relates to the field of process parameter optimization in the thermal oil spraying and heating process of an oil storage tank, and specifically relates to a method for determining optimal parameters for studying the thermal oil spraying and heating process of an oil storage tank. Background technique: [0002] In recent years, the thermal oil circulation method has been gradually put into use in large-scale oil depots because of its high heat transfer efficiency and the elimination of defects that affect the quality of oil products due to equipment failures. Taking Daqing Oilfield as an example, through renovation and new construction, crude oil, finished products Almost all oil tanks have adopted this heating method. [0003] In view of the significant advantages and prospects of further popularization and application of the thermal oil spraying heating process, the basic characteristics of the heating process, especially the distributi...
