ReNew Wilton Hydrothermal Upgrading Demonstration Plant

在2020年2月基准材料价格上涨后，向韧性基金第二链申请将为该项目提供额外的财政支持。这是在2019冠状病毒病大流行之前，最初的智能可持续塑料包装示范项目第一轮拨款提交的时间。该项目包括在Teesside的Wilton International基地建设和优化首个20,000 tpa热液升级示范工厂（HydroPRS），该工厂将把废弃塑料转化为碳氢化合物原料（蜡、油、石脑油），用于生产新塑料和其他化学品，回收塑料中的化学分子。塑料废物的化学回收有望创造下一代的再处理厂。传统的机械回收塑料在可回收的塑料种类、可回收的次数（变色）、机械回收塑料的允许用途、不喜欢多层塑料等方面受到限制。与传统的再处理方法相比，化学回收方法可以容忍更大范围的塑料非同质性。因此，水热升级通过处理其他可能被焚烧或填埋的塑料来补充机械回收，使化学物质可用于生产新塑料，包括食品级塑料和其他成品。该工艺使用超临界水加热，并在催化剂的存在下，将塑料聚合物分解成短链分子。水在提供氢来完成断裂的化学键、降低复杂性和成本方面起着重要作用。这是由Renew ELP有限公司拥有和运营的第一个类型项目，目的是展示HydroPRS技术平台的商业规模设施的可靠运行，为不同的原料建立最佳的反应堆条件，并确认产品质量并建立产品市场。工厂的设计包括预先制造的部件（如挤出机、锅炉）和一系列钢制造部件。预制部件和制造部件的原材料成本都大幅增加。该资助申请是为了支持ReNew ELP团队按时、高质量地交付该项目，并帮助应对化学处理演示器关键组件不可预见的、具有财务挑战性的成本上升。

The Application to the Resilience Fund Strand 2 is to provide additional financial support to the project, following increases to material prices benchmarked in February 2020\. This was the time of the original Smart Sustainable Plastic Packaging Demonstrator Round 1 grant submission, pre-COVID-19 pandemic.The project comprises building and optimising a first-of-its kind 20,000 tpa hydrothermal upgrading demonstration plant (HydroPRS) at the Wilton International site, Teesside, that will convert end of life plastic in to hydrocarbon feedstock (waxes, oils, naphtha) to be used for the production of new plastic and other chemicals, recycling the chemical molecules contained within plastic.Chemical recycling of plastic waste promises to create the next generation of reprocessing plants. Traditional mechanical recycling of plastic is limited in respect of the types of plastic that can be recycled, number of times it can be recycled (discolouration), the allowable uses of mechanical recycled plastic, the dislike of multi layered plastics, etc. Chemical recycling methodologies tolerate a wider range of non-homogeneity of plastics, relative to traditional re-processors. Hydrothermal upgrading therefore complements mechanical recycling by processing these other end of life plastics that might otherwise be incinerated or landfilled, making the chemical available for the production of new plastic, including to food grade, and other finished goods.The process employs supercritical water to heat, and in the presence of a catalyst, to break the plastic polymer into shorter chain molecules. The water plays an important part in providing hydrogen to complete the broken chemical bonds, reducing complexity and cost.The purpose of this first of a type project, owned and operated by Renew ELP Ltd, is to demonstrate the reliable operation of a commercial-scale facility for the HydroPRS technology platform, establish the optimum reactor conditions for different feedstocks, and confirm product quality and establish markets for the products.The Plant's design includes pre-manufactured components (such as an extruder, boilers) and an array of steel fabricated parts. The raw material costs for both pre-manufactured components and those for fabrication have seen significant increases. The grant application is to support the ReNew ELP team to deliver this project to time and quality, and help be resilient to the unforeseen, and financially challenging cost rises in critical components for this chemical processing demonstrator.
