内置锥台电极立式分离器性能试验研究OA

Aiming at the disadvantages of traditional crude oil treatment processes,including large floor area,low efficiency and long treatment duration of gravity settling tanks,a vertical separator equipped with built-in frustum electrodes was developed in this study.A high-frequency and high-voltage pulsed alternating current(AC)power supply was adopted,and the water content at the oil outlet was selected as the evaluation index for separation performance.Demulsification and dehydration experiments of the novel vertical separator with built-in frustum electrodes were carried out to investigate the influences of split ratio,inlet water content,inlet flow rate,and electric field parameters(voltage,frequency,and electric field action time)on the separation performance.The experimental results indicate that there exists an optimal combination of electric field parameters for the vertical separator.Under the operating conditions of an inlet water content of 30%,an inlet flow rate of 100 mL/min and a split ratio of 0.3,the optimal electric field action time,electric field voltage and electric field frequency are 16.5 min,1.85 kV and 3.2 kHz,respectively,achieving a minimum water content of 0.79%at the oil outlet.The influencing degrees of various factors on the separator performance follow the order of electric field voltage>electric field frequency>electric field action time.This study provides a theoretical reference and technical guidance for the research,development and engineering application of high-efficiency vertical separators for the dehydration of crude oil emulsions.
