Method for optimizing crude oil dehydration parameters of pulsed electric field

Abstract

The invention relates to a method for optimizing crude oil dehydration parameters of a pulsed electric field, the method is carried out by utilizing a crude oil dehydration test device of the pulsed electric field and is completed by the following steps of: (1) determining an electric field construction distance; (2) pulse electric field parameter expression considering dehydration medium response; (3) constructing a pulse electric field parameter optimization sequence; (4) optimizing the frequency deviation series; and (5) optimizing the electric field intensity and the duty ratio, completing the optimization of the crude oil dehydration parameters of the pulsed electric field, and obtaining optimized design values of the pulsed electric field parameters (f *, E * and D *). According to the method, the M-N step pulse electric field parameter optimization sequence is established, and the two-dimensional plane sequence of the three-dimensional space sequence under a certain frequency deviation series is used as a discrete point of electric field parameter optimization, so that the optimization of multiple parameters and multiple variables is scientifically simplified, the parameter tuning range is greatly reduced, and the practicability and the accuracy of a parameter optimization design result are effectively improved.
