| dc.description.abstract | Produced water decreases the production of oil and gas and it is currently the largest waste stream in oil and gas industry. In order to reduce the amount of produced water, a chemical treatment using polymers is the focus in this research. Biopolymer xanthan gum (XG) and cross-linker, chromium (III) acetate (Cr(III)) are used in this research work. Polymer additives such as guar gum (GG), Hydroxypropyl methylcellulose (HPMC) and polyvinyl pyrrolidone (PVP) are also used in this research work. One of the statistical techniques used is response surface methodology (RSM), the application of Design of Experiment (DOE). The targeted gelation time of flowing gel phase is between 180 minutes to 240 minutes and the gelation time of solid gel phase is within 1000 minutes to 1440 minutes. Xanthan-chromium (XC) solution form flowing gel at 180 minutes and solid gel at 1265 minutes. For XCG and XCH solutions, the flowing gel phase is formed at 240 minutes and XCP solution form at 235 minutes. Solid gel phase for XCG, XCH and XCP solutions is formed at 1015 minutes, 1440 minutes and 1410 minutes respectively. XCP have better resistance towards brine solutions as the changes can be seen after 80 days. Meanwhile, XC solution changes when meet with synthetic seawater after 75 days. Characterization studies of the solutions shows that the viscosity decreases as the temperature increases, meanwhile the viscosity increases as the time passes by. | en_US |
