Multiphase mixing for pickering emulsions and emusifications models

混合操作和相关技术在知识和科学方面被认为是成熟的。然而，即使在今天，源自混合效率低下的过程损失也会导致不合格产品、化学反应中的选择性差、不期望的副产物等造成数十亿美元的损失。多相混合研究是一门核心化学工程科学，可以生产新的（纳米）材料和高性能产品，将有助于提高加拿大在工程领域的领先地位。阿尔伯塔目前每天挖掘120万桶，鉴于卡尔加里和埃德蒙顿的建筑成本飙升，与运输这一巨大数量有关的挑战不容忽视。在这种已经很困难的情况下，计划在2015年将产量增加到240万桶/日。加拿大东部的炼油厂目前正准备提炼超重油，但目前的石油运输系统仍然不够。乳化后输送石油是一项新技术，具有许多优点，但需要进一步研究。许多乳液聚合方法涉及在油-水界面处存在固体颗粒。它们还涉及乳液相转化，这是最终产品质量的关键步骤，并且通常是不合格产品的原因。如果乳液的搅拌已显示对最终产物施加强烈影响，则尚未研究界面处的固体存在，并且在固体存在下的相转化的进一步研究将有益于产率改进和产物质量。

The mixing operations and related technologies are considered mature in terms of knowledge and science. However, even today, process losses originating from mixing inefficiencies results in billion dollars losses from out-of-specs products, poor selectivity in chemical reactions, undesirable by-products, ... Research in multiphase mixing, a core chemical engineering science allowing for the production of new (nano-) materials and high-performance products, will help increase the Canadian leading position in the engineering field. Alberta currently digs 1.2Mbbl per day and the challenge related to the transportation of this huge quantity cannot be neglected in view of the soaring building costs in Calgary and Edmonton. Adding to this already difficult situation, the production is planned to increase to 2.4 Mbbl/d in 2015. Eastern Canada refineries are currently gearing up to refine extra-heavy oil but the current oil transportation system is still not adequate. Transporting the oil after emulsification is a new technology that offers many advantages but requires additional research. Many emulsion polymerization processes involve the presence of solid particles at the oil-water interface. They also involve emulsion phase inversion that is a crucial step in the final products quality and is often the cause of out-of-spec products. If the agitation of the emulsion has been shown to exert a strong influence on the final product, the solids presence at the interface has not been studied yet and further investigation of the phase inversion in presence of solids will be beneficial to yield improvements and product quality.
