Optimization of Clean Extraction Process for Recovery of Botanical Oils Using Subcritical Water

目前，许多天然石油工业使用易燃化学品、高压程序和极端温度从生物质中提取植物油，无论是从花、茎、根还是叶中提取植物油。这一过程需要极其专业的设备和高设施安全标准，这对工业制造商来说是非常昂贵的。此外，这些基于乙醇的方法需要从所需的石油产品中去除乙醇，这是通过蒸发和蒸馏完成的，并且需要高能量使用过程，导致提取和后处理的高碳足迹。位于安大略省博尔顿的Maratek Environmental Inc.生产环保产品，回收利用多种不同材料产生的废物。Maratek Environmental正在寻求创建一种从生物体中回收植物油的水基提取程序。Maratek Environmental之前曾审查过现有植物油提取方法的潜在危险和低能效。通过开发基于水的提取方法，Maratek Environmental将定位为一家加拿大私营公司，拥有革新和改进提取行业并显著减少危险化学品使用的技术。针对这一点，Maratek Environmental将与Lambton College Research and Innovation Office合作，专注于开发和优化以水为提取介质的植物油提取方法。该项目的成功将使Maratek Environmental能够创建一系列产品，提高安全性，与现有方法的提取效率相匹配，并通过消除昂贵和耗时的蒸馏过程来减少后处理时间。

Currently, many natural oil industries use flammable chemicals, high pressure procedures and extremetemperatures for the extraction of botanical oils from biomass, whether it be from flowers, stalks, roots, orleaves. This processes requires extremely specialized equipment and high facility safety standards which isvery costly for industry manufacturers. In addition, these ethanol-based methods require removal of the ethanol from the desired oil product which is done through evaporation and distillation and requires high energy usage processes, resulting in a high carbon footprint for the extraction and post-processing. Maratek Environmental Inc., located in Bolton, ON, manufactures environmentally conscious products thatrecycle waste for re-use from a number of different materials. Maratek Environmental is looking to is to create a water-based extraction procedure for recovery of botanical oils from biomass.Maratek Environmental has previously reviewed the potential dangers and low energy efficiency of existingextraction methods regarding botanical oils. By developing a water-based extraction method, MaratekEnvironmental will be positioned as a Canadian private sector company with a technology to revolutionize and improve the extraction industry and reduce hazardous chemical usage significantly.In response to this, Maratek Environmental, in collaboration with the Lambton College Research andInnovation Office, will focus on developing and optimizing an extraction method for botanical oils using water as the extraction medium. The success of this project will allow Maratek Environmental to create a product linethat improves safety, matches extraction efficiency of established methods, and decreases post-processing time by eliminating the need for expensive and time-consuming distillation processes.
