项目摘要

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.

Earth Renu Energy Corp.（Earth Renu）是一家不列颠哥伦比亚省拥有和经营的公司，旨在从城市有机废物中获得的生命末期甘油三酯和脂肪酸中生产可持续能源和化学品，更具体地说，是从黄色油脂和油脂收集器废物中获得的。这是一个热门话题，因为加拿大的许多城市开始禁止在垃圾填埋场处理有机废物。用于生产生物柴油的废植物油中的不期望的组分之一是由植物油的降解产生的游离脂肪酸（FFA），这产生了挑战并增加了生产成本。Earth Renu开发了一种专有工艺来去除FFA，并生产出可与初榨植物油相媲美的优质生物柴油原料。FFA去除过程产生废甘油，其可以进一步加工以生产工业甘油和磷酸钾。该研究通过在实验室规模上进行实验，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个完整的甘油和化学品回收工艺，在小规模上经济可行，并应导致地球Renu设计，建造和测试一个商业前的试点工厂。
