A Proposal of Mercury Removal Technique for Oil and Gas Industrial Wastewater

The purpose of this study is to propose the most practical and reasonable technique
to remove mercury from the oil and gas industrial wastewater. Researches has been
shown that there were a lot of techniques that could be implemented by the oil and gas
industry to remove mercury from their waste streams. However insufficient researches
had been conducted to evaluate the suitability and sustainability of the techniques to
the application of oil and gas plant. Therefore, this project analyses numerous
techniques that are possibly having high suitability with the plant’s operation and to
fulfil the Malaysia regulated requirement for the industrial effluent discharge
standards. Based on review of 116 research papers, mercury removal techniques were
accumulated and evaluated using Decision Matrix Analysis tool. The mercury removal
techniques were assessed based on a set of criteria, e.g. mercury removal percentage,
time and cycle of treatment, original mercury concentration in wastewater, and
effective range of temperature for mercury removal.
