印尼油砂多相提取油砂油的工艺
Study on the multi-phase extraction of bitumen from Indonesian oil sands
摘要
Abstract
Indonesian oil sands were separated in a multi-phase extraction system with solvent phase,water washing agent phase and oil sands. The effects ofm(water)∶m(oil sands),pH of water phase,m(solvents)∶m(oil sands) and temperature on the extraction of bitumen from the oil sands were studied. The results showed that, under the optimum technological conditions ofm(water)∶m(oil sands) 0.4-0.6,pH of water phase10-12,m(solvents)∶m(oil sands) 1.0 and temperature 70℃,the bitumen recovery could still be more than 94.5% after the solvents was reused 5 times;with naphtha as the solvent, the bitumen recovery kept above 90.5% after the water washing agent was reused 5 times. The oil content in the tailing sands could be less than 0.3% after two-stage washing with clear water,which could meet the requirement of pollutants in sludges for agricultural use(GB 4284—1984).关键词
