Description
技术领域
本发明涉及一种从油砂中分离沥青的分离组合物及其使用方法,特别涉及采用有效而环境可接受方式从油砂中分离沥青以及从目前的残渣沉淀池中回收剩余沥青的组合物和方法。
背景技术
油砂,又称作“焦油砂”和“沥青砂”,是沥青(焦油)、砂和水的混合物。沥青是一种很重的粘性原油,具有较高的硫含量。沥青从油砂中进行正常分离后,沥青可以加工成合成原油,适合作为生产液体动力燃料、加热油和石油化工的原料。油砂田遍布世界各地。特别是,加拿大拥有巨大的矿藏,包括阿尔伯塔省的阿萨巴斯卡油砂,美国拥有犹他州油砂,在南美洲,委内瑞拉的奥林纳哥油砂,以及非洲的尼日利亚油砂。世界上已知石油中大多数都存在于油砂中。
沥青是很难以环境可接受方式有效地从油砂中分离。目前,人们从油砂中分离沥青的做法一般都只能获得可用沥青的85-92%。此外,目前,从油砂中分离沥青的方法包括在加工处理期间生成乳液,或者“泡沫体”,这要求使用对环境有害的有机溶剂-诸如石脑油-来“裂化”乳液,以便进一步加工处理。此外,油砂的砂子(以及其它颗粒物质,诸如粘土)部分中留存的沥青对生成重淤渣-通常称之为“残渣”-有一定作用。残渣由未回收的沥青、砂(和其它颗粒物质)以及水组成,目前处理残渣的做法是,将残渣注入到巨大的残渣沉淀池内,在这里,砂子和其它颗粒物质在几年期间缓慢沉淀和分层。

具体实施方式
下面给出一些实施例,来说明各种实施方案,但这些实施例不应视为本发明的范围仅限于此。
实施例1-从阿萨巴斯卡油砂中分离沥青
准备300g的如下分离组合物,其pH值大约7.8,将其置放在一个1L的烧杯内:
向装有分离组合物的烧杯内注入300g的阿萨巴斯卡油砂。将合成的浆体加热到54℃到60℃。将一个高剪切实验室用混合器放入烧杯内,以每分钟3500转的速度搅拌浆体,时间为3分钟。将混合器从烧杯中取出。在随后的5到30分钟内,在烧杯内就会产生完全相分离。观察到四个不同的清晰的相态。顶部即第一层内含有沥青。第二层含有分离组合物。第三层含有粘土。底层即第四层含有砂子和其它颗粒物质。
让烧杯内的物质冷却,在此期间,将沥青从烧杯中排出。测定沥青应99%以上无杂质,包括砂和粘土。回收的沥青接近45g,占油砂试样中所有可用沥青的99%以上。
另外,回收砂子,测定其99%以上无沥青。该砂子置放在烘箱内,温度72℃,时间8小时,而后在冷却到室温后,砂子可以通过20-25目的筛子来筛除。
为了进一步了解油砂中所存留的沥青含量,可在烧杯内置放100.00g的干砂,向砂子内添加100g的甲苯。搅拌所形成的浆体,然后,使其沉淀。将甲苯从砂子中轻轻倒出。目视检查所倒出的甲苯,发现很清澈。将砂子再次在温度72℃下烘干,时间8小时,以便蒸发任何残余的甲苯。而后,对砂子进行称重,剩余的砂子为99.86g。
在另一个1L的烧杯中,放入300g新的分离组合物的等分试样。向新的分离组合物中添加45g分离后的回收的沥青。将分离组合物和沥青加热到72℃,并以每分钟2000转的速度搅拌,时间3分钟。让烧杯中的物质冷却,并按上述方式分离。最后形成的沥青可以完全无任何杂质。
在沥青被取出后,可从第一个1L的烧杯中取出原来的分离组合物。将275g的该分离组合物添加到1L的烧杯中。向烧杯内注入新的阿萨巴斯卡油砂等分试样。将浆体加热到72℃,以每分钟3000转进行搅拌,时间3分钟。
让烧杯内的物质冷却,在此期间,将沥青从烧杯中排出。测定沥青99%以上无杂质,包括砂子和粘土。回收的沥青接近41g,占油砂试样中可用沥青的99%以上。
另外,回收砂子,测定其99%以上无沥青。该砂子置放在烘箱内,温度72℃,时间8小时,而后在冷却到室温后,砂子可以通过20-25目的筛子来筛除。
