Removal of Emulsified Oil from SAGD Produced Water by Adsorption Coupled with Electrochemical Regeneration
Abstract
Adsorption is an effective method for oil removal as it is a simple process with low processing costs. In order to make the adsorption process cost-effective, not only the adsorbent adsorptive capacity but also regeneration performance should be considered.
Graphite intercalation compound (GIC) is a non-porous material with good electrical conductivity. These characteristics make GIC suitable for an innovative adsorption/regeneration process. Adsorption and regeneration processes are done in the same device and GIC is electrochemically regenerated after each adsorption cycle.
In this study, the performance of the technology for removing oil from SAGD produced water and synthetic emulsions was studied. Effective and fast oil removal achieving in less than 30 min and full recovery of adsorbent adsorptive capacity was among the promising results. Energy consumption for regeneration of adsorbents was 22.4 and 35.8 kWh per kg of COD to be treated for treatment of synthetic emulsion and produced water, respectively.
