摘要/Abstract

摘要： 海上平台采出水处理系统中气浮罐因维护较困难,导致其除油效果随服役年限的增长而降低,显著增加了采出水的处理成本。为改善处理效果,拟将其改造为电气浮罐,在满足除油效果的同时,对采出水起到一定的氧化、杀菌作用,从而减轻后续流程的压力。但目前电气浮罐尚无工业化实践,相关研究也较为缺乏。为探讨电气浮罐改造的可行性,利用Fluent软件对电气浮罐除油的处理过程进行稳态模拟,考察了电流密度、停留时间等参数对处理水中油含量的影响。模拟结果显示:水相出口油含量随停留时间的延长而减小,随电流密度的增大而减小,且随电流密度变化更为明显;电气浮罐在电流密度为150 A/m²、停留时间为20 min的条件下可以达到最优工况,该条件下可以将油含量处理达标,油含量由1 000.00 mg/L降至62.54 mg/L。该结果明确了电气浮罐改造的可行性,可为后续海上平台老旧气浮罐的改造提供技术参考。

Abstract: In offshore platform produced-water treatment systems,gas flotation tanks are difficult to maintain,leading to reduced oil removal efficiency as service time increases,which significantly increases the cost of produced water treatment.To improve the treatment effeciency,it is proposed to retrofit the unit into an electroflotation tank that can provide certain oxidation and sterilization effects on the produced water while maintaining oil removal performance,thereby reducing the burden on subsequent processes.However,at present there is no industrial implementation of electroflotation tanks,and related research is scarce.To investigate the feasibility of the electroflotation tank retrofit,steady-state simulations of the oil removal process in an electroflotation tank were carried out using Fluent software to exa mine the effects of current density,residence time,and other parameters on the oil content of the treated water.The simulation results show that the oil content at the water outlet decreases with increasing residence time and with increasing current density,and the latter effect is more obvious.The electroflotation tank can achieve optimal performance at a current density of 150 A/m² and a residence time of 20 minutes,under which the oil content is reduced from 1 000.00 mg/L to 62.54 mg/L,meeting the discharge standard.This result demonstrates the feasibility of retrofitting an electroflotation tank and can provide technical reference for upgrading aging flotation units on offshore platforms.
