ABSTRACT

The influence of the distance between electrodes, electrical current, and flow rate of emulsified crude oil in water effluent through an electrocoagulation reactor was studied. Power switch at an interval of 30 s was used to reduce electrode passivation. The output variables were power consumption, pH, and oil removal from effluent. There was no significant change in the output variables with the working time of the reactor. The final pH was between 7.5 and 9.5 depending on the input variables. It increases with higher electrical current and tends to decrease with increased flow rate. Increasing electrical current tends to increase while increasing either distance between electrodes or the flow rate tends to reduce oil removal. Using a 2.88 L reactor, it is possible to treat 7.12 L of effluent in one hour, removing 78% of the crude oil, keeping final pH at 8.3, and this system will have an energy consumption of 21.6 kWh.

摘要

研究了电极间距离、电流和乳化原油在通过电凝聚反应器的出水中的流量的影响。以 30 秒为间隔的电源开关用于减少电极钝化。输出变量是功耗、pH 值和流出物中的油去除率。随着反应器的工作时间，输出变量没有显着变化。根据输入变量，最终 pH 值介于 7.5 和 9.5 之间。它随着更高的电流而增加，并随着流量的增加而趋于降低。增加电流趋于增加，而增加电极之间的距离或流速趋于减少油去除。使用 2.88 L 反应器，可在一小时内处理 7.12 L 出水，去除 78% 的原油，
