The latest research and development in hydrothermal carbonisation (HTC) processes are reviewed and the feasibility of application to small towns in the UK is assessed. The HTC process designed in this report is theoretically evaluated for the biodegradable municipal waste and sewage waste produced by the small town of Chirnside, in the Scottish Borders. Calculation of mass and energy balances of the process are carried out alongside the evaluation of challenges and environmental, social and economic opportunities presented. The hypothetical HTC plant is capable of processing 267.14 t per year of food waste and 105.12 t per year of faecal sludge produced by Chirnsides estimated 2250 residents in 2041. The plant would be capable of producing 99.08 t per year of hydrochar with an estimated total energy content of 540.26 MWh per year. When used in a Biomass Combined Heat and Power Plant, the hydrochar would be capable of supplying Chirnsides residents with 0.71% and 3.43% of its domestic thermal energy demand and domestic electrical energy demand in 2041, respectively. Both the expected opportunities and challenges for the application of HTC are discussed, shedding light on the associated research in regards to this sustainable technology.
本文综述了水热碳化（HTC）工艺的最新研发进展，并评估了其在英国小镇应用的可行性。本报告设计的HTC工艺针对苏格兰边境的奇恩赛德小镇产生的可生物降解城市垃圾和污水进行了理论评估。在评估该工艺所面临的挑战以及所带来的环境、社会和经济机遇的同时，还进行了该工艺的质量和能量平衡计算。假设的HTC工厂每年能够处理奇恩赛德镇预计在2041年产生的2250名居民所产生的267.14吨食物垃圾和105.12吨粪便污泥。该工厂每年能够生产99.08吨水炭，估计总能量含量为每年540.26兆瓦时。当用于生物质热电联产厂时，水炭分别能够满足奇恩赛德镇居民在2041年0.71%的家庭热能需求和3.43%的家庭电能需求。文中讨论了HTC应用的预期机遇和挑战，为这项可持续技术的相关研究提供了参考。
