Kinetic Study of Adsorption of Oil from Oilfield Produced Water Using Modified Porous Ceramics Filtration Media in Column Mode
Adsorption kinetic for oil in the oilfield produced water (OPW) onto modified porous ceramics filtration media (MPCFM) in fixed bed column was studied. Porous filtration media was modified with containing hydrogen silicone oil (CHSO). The effects of important parameters, such as filtering velocity, initial oil content and filtering layer thickness, on oil removal were discussed. The experimental column data were fitted to Yoon and Nelson model equations using linear regressive analysis, next, kinetic parameters were figured out and oil removal mechanism was analyzed. All the results suggested that reducing filtering velocity, increasing oil content and filtering layer thickness make for oil removal, and mechanism of oil adsorption removal be wetting adsorption coalescence. Farther, adsorption of oil onto filtration media followed Yoon and Nelson kinetic model well by entirely fitting (at low and middle oil content) or stepwise fitting (at high oil content).
