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，混合效率低下导致的过程损失也会导致数十亿美元的损失，原因包括不合规格的产品、化学反应的低选择性、不受欢迎的副产品……多相混合是生产新型（纳米）材料和高性能产品的核心化学工程科学，多相混合的研究将有助于提高加拿大在工程领域的领先地位。艾伯塔省目前每天开采120万桶石油，考虑到卡尔加里和埃德蒙顿不断飙升的建筑成本，运输这一巨大数量的挑战不容忽视。雪上加霜的是，该地区的产量计划在2015年增加到240万桶/天。加拿大东部的炼油厂目前正在加紧提炼超重油，但目前的石油运输系统仍然不够。乳化后的油运输是一项新技术，具有许多优点，但需要进一步的研究。许多乳液聚合过程涉及在油水界面存在固体颗粒。它们还涉及乳液相转化，这是最终产品质量的关键步骤，通常是导致产品不合规格的原因。如果乳化的搅拌对最终产物有强烈的影响，那么界面处的固体存在尚未得到研究，进一步研究固体存在下的相转变将有利于收率的提高和产品质量的提高。

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.
