The research proposal deals with cleaning of extracted bitumen from Athabasca oil sands. The recovered bitumen typically contains 30wt% water, part of which is emulsified. The emulsified water is present as very small drops of few microns in size. The removal of the water prior to bitumen upgrading is essential as the water contains chloride salts that would cause corrosion in the upgrading equipment. We found that one type of ethylcellulose polymers, a biodegradable and environmentally friendly polymer, to be an excellent candidate that assists in the break-up of the emulsified water drops in the bitumen.

该研究计划涉及从阿萨巴斯卡油砂中提取沥青的清洁。回收的沥青通常含有30重量%的水，其中一部分被乳化。乳化水以几微米大小的非常小的液滴存在。在沥青改质之前除去水是必要的，因为水含有氯化物盐，氯化物盐会引起改质设备的腐蚀。我们发现，一种类型的乙基纤维素聚合物，一种可生物降解和环境友好的聚合物，是一个很好的候选人，有助于在沥青中的乳化水滴的分裂。
