Development of a Prototype Pre-Production High Throughput Anaerobic Digester (HTAD)

目前的商业化厌氧消化（AD）装置效率低，技术含量低，规模大，只能在非常狭窄的操作条件范围内可靠运行。新一代沼气有限公司正在深入研究AD和现代过程控制技术，开发高通量厌氧沼气池（HTAD）。沼气生产效率的显著提高将从根本上改变小型厌氧沼气池的经济性，并实现对单一农场AD工厂的未满足需求，以及由水务公司进行具有成本效益的污水处理。预计大多数投入的投资回收期为5年或更短，而高能量原料的投资回收期明显更短。研究和可行性研究的结果将应用于开发一个生产前原型HTAD工厂，并进行一个试验方案。后者的目标是：改进HTAD的设计和测量性能，降低成本，用一系列原料测试性能，改进控制系统，使HTAD易于客户使用，并为未来的销售生成营销数据。开发项目的产出将用于建造和销售一系列模块化HTAD。英国将受益于建立一个新的以研究为基础的制造业，拥有多样化的国内和出口市场，在一个制造业非常有限的地区拥有非常良好的长期前景。HTAD有能力为政府的气候变化议程做出重大贡献，因为该项目通过从动物粪便、食物垃圾和有机工业废物中捕获甲烷来减少温室气体（GHG）；它还减少了一氧化二氮的排放。

Current commercial Anaerobic Digestion (AD) plants are inefficient, low-tech and large scale, only capable of reliable operation within a very narrow range of operating conditions. New Generation Biogas Ltd is exploiting research into AD and modern process control technology to develop a High Throughput Anaerobic Digester (HTAD). A significant increase in biogas productivity will radically change the economics of small Anaerobic Digesters and realise an unfulfilled need for Single Farm AD plants and cost effective sewage processing by Water Companies. A payback period for most inputs of the order of 5 years or less is predicted, significantly less for higher energy feedstocks.The results of research and feasibility studies will be applied to the development of a preproduction prototype HTAD plant and to conduct a trials programme. The objectives of the latter are to: refine the HTAD design and measure performance, reduce costs, testperformance with a range of feed stocks, refine the control system to make the HTAD easy for customers to use and to generate marketing data for future sales. The outputs of the development project will be used to build and market a range of modular HTAD.Benefits to the UK will arise from the establishment of a new research based, manufacturing industry with varied, home and export markets and very sound long term prospects in an area with very limited manufacturing industry. The HTAD has the capability to make a significant contribution to the Government’s Climate Change agenda as AD reduces Greenhouse Gases (GHG) by capturing methane from animal manure, food waste and organic industrial waste; it also reduces nitrous oxide emissions.
