ReNew Wilton Hydrothermal Upgrading Demonstration Plant

该项目包括在Teesside的Wilton International基地建设和优化首个20000吨/年热液升级示范工厂（Cat-HTR），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，回收塑料中含有的化学分子。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首个项目，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，确认产品质量并为产品建立市场。位于达灵顿的Wood Group**是被选中交付第一个项目的工程承包商。Wood的国际能力意味着，在成功完成示范项目后，它将很好地在全球范围内提供这项技术。**华威制造集团**（华威大学-高价值制造弹射器的一部分）参与该项目，通过对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）来协助优化工厂。

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).
