Experimental Study on Hydrogen Production Process by Electrolysis of Water Produced from Oil Fields
摘要
Abstract
To achieve green resource utilization of oilfield produced water,this study proposes an integrated process of electrochemical pretreatment-electrolytic hydrogen production,using produced water from Changqing Oilfield as the treatment target.A synergistic pretreatment system incorporating electro-demulsification,electro-coagulation,and electroflotation was constructed to investigate the effects of parameters such as current intensity and hydraulic loading on pollutant removal efficiency.Additionally,an operational evaluation system for the hy-drogen production system was established.Results demonstrate that under optimized pretreatment conditions(3 A for electro-demulsification,3 A for electrocoagulation,4 A for electroflotation;a flow rate of 10 L/h),oil re-moval efficiency,turbidity reduction rate,and suspended solids removal rate reached 92.32%,93.30%,and 94.66%,respectively.In the hydrogen production stage,under operational parameters of current density 0.4 A/cm2,a rotational speed of 23 r/min,a temperature of 85℃,and an electrolyte concentration of 6 mol/L KOH,the hydrogen purity attained 96.58%,the process energy consumption was reduced by 34.8%,and the cost was reduced by 12.6%.This integrated process enables deep purification of produced water and efficient hydrogen generation through electrochemical synergism,providing an innovative technical solution for wastewater treatment and green hydrogen co-production.The findings hold significant engineering value for advancing low-carbon energy transition in oilfields.关键词
