Development of a recovery process to produce glycerin, glycerides, free fatty acid (FFA) and potassium phosphate from the byproduct of a process removing FFA from used cooking oil

Earth Renu Energy Corp.(Earth Renu)是一家不列颠哥伦比亚省拥有和运营的公司，致力于从城市有机废物中获得生命末期的甘油三酯和脂肪酸，更具体地说，从黄色油脂和隔油器废物中生产可持续能源和化学品。随着加拿大许多市政当局开始禁止在垃圾填埋场处置有机废物，这是一个热门话题。用于生产生物柴油的废弃植物油中的有害成分之一是游离脂肪酸(FFA)，它是由植物油降解产生的，这给生产带来了挑战，增加了生产成本。Earth Renu开发了一种专有工艺来去除FFA，并生产一种优质的生物柴油原料，可与原始植物油相媲美。去除游离脂肪酸的过程产生废甘油，这些甘油可以进一步加工以生产工业甘油和磷酸钾。拟议的研究通过在实验室规模进行实验，并通过计算机模拟优化工艺，扩展了废甘油精制工艺的可行性。该研究项目旨在开发一套完整的甘油和化学回收工艺，在小规模上经济可行，并应导致Earth Renu设计、建造和测试一个商业化前的试点工厂。

Earth Renu Energy Corp. (Earth Renu) is a B.C. owned and operated company seeking to produce sustainable energy and chemicals from end of life triglycerides and fatty acids obtained from urban organic waste, and more specifically from yellow grease and grease trap waste. This is topical as many municipalities in Canada are starting to ban disposal of organic wastes in landfills. One of the undesirable components in waste vegetable oil for the production of biodiesel is the Free Fatty Acid (FFA), resulting from the degradation of vegetable oil, which create challenges and increase production costs. Earth Renu has developed a proprietary process to remove the FFA and produce a premium feedstock for biodiesel production, comparable to virgin vegetable oil. The FFA-removal process generates spent glycerin, which can be processed further to produce technical glycerin and potassium phosphate. The proposed research extends the feasibility of the spent glycerin refining process by running experiments in a lab scale, and optimizing the process through computer simulations. The research project will aim at developing a complete glycerin and chemical recovery process, economically viable on a small scale, and should lead to Earth Renu designing, building and testing a pre-commercial pilot plant.
