“…The synthetic SP produced water was prepared by mixing the brine, Dulang crude oil and various SP concentration based on the previous research. Synthetic SP produced water emulsion was prepared by mixing the MFOMAX (250-500 ppm) [4,23], GLP-100 (450-900 ppm) [23][24], Dulang crude oil with initial concentration of 1000 ppm [18,25] and brine at 14000 ppm (…”

The objective of this study was to investigate the effect of polymer and surfactant (MFOMAX) towards the efficiency of oil removal in a flotation column by using the Response Surface Methodology (RSM). Various concentrations of surfactant (250, 372 and 500 ppm) and polymer (450, 670, and 900 ppm) produced water were prepared. Dulang crude oil was used in the experiments. Flotation operating parameters such as gas flow rate (1-3 L/min) and duration of flotation (2-10 min) were also investigated. The efficiency of oil removal was calculated based on the difference between the initial concentration of oil and the final concentration of oil after the flotation process. From the ANOVA analysis, it was found that the gas flow rate, surfactant concentration, and polymer concentration contributed significantly to the efficiency of oil removal. Extra experiments were conducted to verify the developed equation at a randomly selected point using 450 ppm of polymer concentration, 250 ppm of surfactant concentration, 3 L/min gas flowrate and duration of 10 min. From these extra experiments, a low standard deviation of 1.96 was discovered. From this value, it indicates that the equation can be used to predict the efficiency of oil removal in the presence of surfactant and polymer (SP) by using a laboratory flotation column.

2015): The effect of bubble size on oil-water separation efficiency for a novel oil-water separation column, Separation Science and Technology, Abstract: Bubble size is a key factor in froth flotation for oil-water separation. In this paper, the bubble size which impact on oil removal efficiency for a novel oil-water separation column was researched systematically. The bubble size distribution was researched by using the photographic method and Matlab software. In addition, several operating parameters which impact on the bubble size were investigated, including circulating pressure, aeration rate and the foaming agent. Based on the results of experimental data and image analysis, the frother consumption and aeration rate has important influence on the bubble size. The bubble size can be controlled by adjusting the operation conditions including the circulating pressure, aeration rate and the frother consumption. The optimum operating conditions for the oil-water separation column were determined. Furthermore, the mathematical model of oil removal efficiency for the oil-water separation column was established.

“…The cyclonic-static microbubble flotation column was always used in mineral processing and coal preparation processing before it has been introduced in water treatment. Under the optimum operating parameters, the oil content in the final effluent reached to the 16.49 mg/dm 3 [10,11]. But the functional mechanism of the cyclonic-static microbubble flotation column used in oil-water separation is not clear.…”

A cyclonic-static microbubble flotation column of a novel construction was used in oil-water separation fields and has high efficiency for oil-water separation. The gas holdup is a key parameter for the evaluation of the performance of a flotation column. The gas holdup, closely related to the bubble size, bubble velocity and superficial gas velocity, is one of the most important parameters characterizing the hydrodynamics of a bubble column. The effect of gas holdup in a cyclonic-static microbubble flotation column was investigated. In addition, several operating parameters such as the circulating pressure, superficial gas velocity, and frother consumption were also investigated. The gas holdup was positively correlated to the superficial gas velocity. The gas holdup of clean water and oil wastewater increased along with the increase of the frother consumption. The separation mechanism of cyclonic-static microbubble flotation column was analyzed.
