- Figure 1 shows an example of process flow related to the present invention involving different steps as listed below.
- Process I Dispersion and oil removal; breaking down the oily solid cluster, dispersing the solid and oil removing/degreasing simultaneously.
- the invented emulsified composition and/or alkaline salt are added into this process to treat the oily solid.
- Process II Decantation to separate liquid (water with emulsified/removed oil) from solid.
- Process III Washing with water or mixed co-solvent with water. This washing step aims to remove the remaining composition of the cleaning chemical solution and also eliminate the effect of adsolubilization (oil solubilized by surfactant admicelles on solid surface) by dilution and surfactant desorption.
- Process IV Decantation to separate liquid (water with emulsified/removed oil) from clean solid;
- Process V a Drying; at the temperature around 80-100 °C aiming to remove moisture and remaining light oil replacing the heavy oil in the sample during the cleaning process; and Process V b : De-Oiling water; water treatment with de-oiler ( ⁇ 1000 ppm).
- the invented emulsified composition presented in following examples are water-in-oil nanoemulsion with oil-water interfacial tension lower than 0.01 mN/m (measured at 25 °C by KRUSS spinning drop tensiometer; model SITE 100).
- the mean particle size of the nanoemulsion is smaller than 100 nm (measured at 25 °C by particle size analyzer; Malvern Zetasizer Nano ZS).
- the oily solid samples listed in TABLE 1 are the samples used in testing various embodiments of the present invention. The properties of each oily solid sample were determined by using the retort analysis. All samples are actual specimens from Oil & Gas industrial processes.
- the efficiency of the invented oily solid treatment method and cleaning chemical composition was evaluated with different process steps and cleaning chemicals used.
- the efficiency of the process was referred to the total oil content in the solid after final treatment.
- Oil content was determined by the retort analysis and/or Soxhlet solvent extraction (if the oil content was expected to be ⁇ 1 w/w%).
- the typical target of the oil content in the solid after treatment is ⁇ 1 w/w%.
- Sample A which is drill cuttings had been used for the experiment in this EXAMPLE.
- Sodium carbonate, sodium tripolyphosphate and potassium hydroxide had been used as the alkaline salt to adjust the pH of the cleaning solution to 8-12.
- the cleaning solution/sample ratio is 1/1 by weight.
- the washing solvent was water or water mixed with co-solvent (ethylene glycol, isopropanol, or butoxyethanol).
- Water was the solvent of cleaning solution for the first process step.
- the % concentration of cleaning solution is the % compared with the treated sample weight otherwise stated.
- Cleaning solution/sample ratio was 1/1 by weight.
- This experiment also compares the efficiency between the invented method and cleaning composition (Experiment A4-A15) and the conventional surfactant cleaning method (Experiment A1-A3). All cleaning methods were conducted at room temperature, except the drying process in the final treatment step.
- this conventional surfactant was not effective possibly because of another two reasons (1) oil/water interfacial tension induced by this surfactant might not be sufficiently low and (2) the wax or heavy oil strongly adsorb on the solid surface, as well as, the heavy oil molecularly blended with the trapped light oil helping light oil to be trapped together with heavy oil and difficult to be emulsified.
- the invented emulsified composition with and without sodium carbonate (alkaline salt) were mixed in water to produce treating solution to clean the solid Sample A (drill cuttings) with the original oil content of 13 w/w% (Experiment A4-A15).
- Experiment A6 shows that if Sample A was treated with cleaning solution consisting of 1 w/w% of the invented emulsified composition and 5 w/w% sodium carbonate and subsequently washed with water without drying process in the last process step, the oil content in the solid after treatment was about 3.6 w/w% without drying process in the final process step, possibly because the emulsified oil and wax were still trapped in the void space between the solid particles, which was promoted by adsolubilization phenomena (oil solubilized by surfactant admicelles on solid surface). The oil removal efficiency of this process was slightly improved when the concentration of the invented emulsified composition was increased from 1 to 5 w/w% without drying process in the final step.
- the treatment of different kinds of oily solid samples was evaluated in this example.
- the cleaning solution in the first process step contains 1 w/w% of the invented emulsified composition and 5 w/w% sodium carbonate in water. Water was used as the washing agent in the washing step. All experiments used drying process as the final treatment step. It was indicated that the oil could be efficiently removed from the solid for sample A, B and C (experiment A6, Bl and CI, respectively) effectively, reducing the oil content in the solid samples from 12-13 w/w% to ⁇ 1 w/w%.
- experiment D2 Another experiment using higher dosage of the invented emulsified composition and sodium carbonate was conducted in experiment D2 to improve the cleaning efficiency.
- the oil content in the solid after final process step was still higher than 1 w/w%. Improvement by using water/co-solvent (butoxyethanol) mixture for washing step was exhibited in experiment D3.
- the oil content in the solid after final treatment could be successfully reduced to ⁇ 1 w/w%.
- % Concentration of cleaning solution is the % compared with the treated sample.
