ReNew Wilton Hydrothermal Upgrading Demonstration Plant

该项目包括在蒂赛德的威尔顿国际工厂建造和优化首个20000 TPA水热升级示范工厂(Cat-HTR)，该工厂将把使用寿命结束的塑料转化为碳氢化合物原料(蜡、油、石脑油)，用于生产新的塑料和其他化学品，回收塑料中包含的化学分子。塑料废物的化学回收有望创建下一代后处理工厂。传统的塑料机械回收在可回收塑料的类型、可回收的次数(变色)、机械回收塑料的允许用途、对多层塑料的厌恶等方面受到限制。与传统的再处理机相比，化学回收方法容忍更广泛的塑料的异质性。因此，水热升级是对机械回收的补充，通过处理这些生命周期结束时可能被焚烧或填埋的塑料，使化学物质可用于生产新塑料，包括食品级和其他成品。该过程使用超临界水加热，并在催化剂的存在下，将塑料聚合物分解为较短的链分子。水在提供氢气以完成断裂的化学键、降低复杂性和成本方面起着重要作用。这个由**RENEW ELP有限公司**拥有和运营的第一个类型项目的目的是展示CAT-HTR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，并确认产品质量和为产品建立市场。位于达灵顿的**Wood Group**是被选中交付这个第一个项目的工程承包商。伍德的国际能力意味着，在示范项目成功完成后，它将很好地在全球范围内交付这项技术。**华威制造集团**(华威大学-高价值制造Catapult的一部分)参与了该项目，通过投入和产出的技术分析，以及环境分析和结果解释以及生命周期评估(LCA)，帮助优化工厂。

The project comprises building and optimising a first-of-its kind 20,000 tpa hydrothermal upgrading demonstration plant (Cat-HTR) 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 CAT-HTR technology platform, establish the optimum reactor conditions for different feedstocks, and confirm product quality and establish markets for the products.**Wood Group** based in Darlington is the engineering contractor selected to deliver this first project. Wood's international capabilities means that it is well placed to delivery this technology worldwide following successful completion of the demonstration project.**Warwick Manufacturing Group** (University of Warwick - Part of High Value Manufacturing Catapult) is engaged on the project to assist in optimising the plant through the technical analysis of inputs and outputs, alongside environmental analysis and interpretation of results and through Life Cycle Assessment (LCA).
