PROCESS, METHOD, AND SYSTEM FOR REMOVING HEAVY METALS FROM OILY SOLIDS |
摘要 |
Oil is recovered from a mercury containing oily solids by mixing the solids with at least a treating agent selected from selected from flocculants, sulfidic compounds, demulsifiers, and combinations thereof, and optionally a solvent, forming a mixture. The mixture is then separated to recover a first phase containing treated oil having less than 50% of the original amount of mercury in the oily solids, and a second phase containing treated solids having a reduced concentration of mercury. In one embodiment, the oily solids are selected from drilling muds; oily sediments coating inside of pipelines; sediment deposits on crude oil tanks, vessels, and separators; surface coating on equipment; slop oil from upstream operations; oily solids from heavy oil processing operations; abradants; solids recovered from processes for removing mercury from hydrocarbon materials; filter-aid materials from mercury removal operations; spill clean-up materials; and mixtures thereof. |
