Heavy oil utilisation is set to increase over the coming decades as reserves of conventional oil decline. Heavy oil differs from conventional oil in containing relatively large quantities of asphaltene and carboxylic acids. The proportions of these compounds greatly influence how oil behaves during production and its utilisation as a fuel or feedstock. We report the development of a microfluidic technique, based on a H-cell, that can extract the carboxylic acid components of an oil and assess its asphaltene content. Ultimately this technology could yield a field-deployable device capable of performing measurements that facilitate improved resource management at the point of resource-extraction.
随着常规石油储量的下降，重油的使用量在未来几十年将增加。重油与常规石油的不同之处在于，它含有相对大量的沥青质和羧酸。这些化合物的比例极大地影响了石油在生产过程中的表现以及作为燃料或原料的使用。我们报告了一种基于H型电池的微流控技术的开发，该技术可以提取油中的羧酸成分并评估其沥青质含量。最终，这项技术可能会产生一种可在现场部署的设备，能够进行测量，有助于在资源开采点改善资源管理。
