Talk Title: Electroremediation of Offshore Muds Contaminated with Heavy Metals

Abstract:
The electroremediation process requires much needed research work to be optimized for up-scaling and improving economic efficiency. This is particularly true when applying the technology to highly heterogeneous and complex mineralogy materials such as offshore sediments and muds. Laboratory batch tests were performed on field retrieved specimens of contaminated offshore muds near Abu Dhabi Ports of United Arab Emirates. The influence of various process parameters that determine the optimum operating conditions and sustainable enhancement of electrokinetic remediation was investigated. Excellent results of decontamination of seven heavy metals were achieved. The removal of heavy metals by management of the in-situ chlorine gas (Cl2) production was also investigated. The tests showed a high removal efficiency of heavy metals at the cathode end of cores after 24 hours of EK application. Electrokinetics is also proposed to improve acidizing operations, i.e., increase the penetration distance. Aqueous solutions of hydrochloric acid (usually 15%) are pumped into the carbonate formations to enlarge the pores and pre-existing fractures. However, the penetration distance of acid is very short. By applying D.C. current, one can drive the acid for long distances into the formation being acidized.
