准确性高于假设:为什么对单一全球碳核算模型的需求从未如此强烈
可再生天然气(RNG)或替代天然气(SNG)生产是实现住宅供暖和运输系统等终端需求脱碳的最灵活方法之一.
Renewable natural gas produced from biogas, power-to-gas and biomass gasification, is a clean and low-carbon alternative to conventional natural gas, that can be transported and distributed using the existing grid infrastructure.
Wood的VESTA催化甲烷化技术为天然气生产提供了一种高效的方法, 健壮的 and viable system that can be adapted to any source of syngas (e.g., from biomass or waste gasification), including the CO2-富气,通常用于沼气升级和基于绿色氢气和其他过程产生的二氧化碳的电力制气应用.
可再生天然气是一种清洁、优良的能源载体,可直接引入现有的天然气管网. 生物基市场领域的应用包括住宅供暖(包括烹饪)。, cogeneration and transportation systems.
The biogas sector represents a production potential of renewable gas of 10 billion Nm3 of biomethane by 2030 (90% from agriculture matrices and 20% from organic wastes, non-biogenic sources and gasification). The production of biomethane delivers a reduction in greenhouse gas emissions.
由于生产工厂易于与现有天然气网络连接以及成熟技术的可用性,可再生天然气预计将在能源领域发挥关键作用, 比如灶神星, for commercial applications.
Wood developed a simple methanation process called VESTA, powered by a high-performance catalyst from our partner, 科莱恩.
VESTA通过三种替代工艺方案利用可再生资源,减少对化石燃料的依赖,实现天然气生产的脱碳:
第一种途径是通过使用独特的工厂配置(取决于所选择的气化技术)来生产清洁气体,这将对下游合成气成分产生影响, 随后, on the cleaning steps.
沼气和可再生氢气,以增加天然气产量,减少二氧化碳排放
CO2通过使用可再生氢气和随后的干燥段将富天然气转化为绿色天然气.
在不同地区的政府激励下,生物质气化工厂在经济上具有吸引力(例如,先进生物燃料原料激励或替代燃料走廊(AFC)赠款以及英国和欧洲大陆的类似计划)。, 在北美也是如此,或者作为一种整合和利用低品位热量的途径.
沼气升级 and power-to-gas systems allows the widest use of RNG, not only for power generation but to provide an alternative for transport, industrial and domestic energy demands in all green economies.
A unique, once-through methanation technology
与其他甲烷化方法相比,VESTA的优势在于其充分的灵活性,可以平衡资本和运营支出, and the adaptation of any source of syngas, 比如煤, biomass or waste gasification, biogas upgrading and power-to-gas application.
In contrast to other available technologies, VESTA采用了一遍通过的过程,在甲烷化反应器的下游进行二氧化碳去除,而不是在甲烷化部分之前.
该策略消除了对产品回收压缩机的需求,减少了相关的电力消耗和安装成本,同时防止了甲烷化部分失控的风险,因为二氧化碳起到了温度抑制器的作用,减轻了该过程的高放热性.
催化剂的伴侣
The high-performance catalyst for the methanation reactors is provided by our partner 科莱恩. 科莱恩’s high-stability, non-precious metal catalyst is ideal for the increased operating range of 230-700oC contributing to a superior outcome.
Wood对以下三种小规模和多用途商业应用的天然气生产途径进行了技术和经济评估:
The biobased sector is getting unforeseen interest and investment in Europe. Considering current incentives, 生物质气化后进行适当的抛光步骤和清洁气体甲烷化是一种可行且具有经济吸引力的生产可再生天然气的解决方案.
沼气升级 provides an efficient, 健壮的, and viable system to produce bio-SNG that can be delivered, transported and distributed using existing natural gas infrastructure.
电能制气的利用与沼气升级生产清洁合成气和随后的生物制煤天然气一样可行和高效,后者可以整合到现有的天然气网络中,用于运输和供暖.
First of its kind waste-to-SNG demonstration plant
Wood has partnered with the UK government and Advanced Plasma to build the first waste-to-energy SNG plant using the 灶神星甲烷化 technology.
超清洁替代天然气示范工厂由英国运输部和国家电网天然气分配公司资助,并与Advanced Plasma 权力公司的Gasplasma®技术合作建造.
该工厂将生物质转化为合成气,然后使用Wood的VESTA SNG技术将合成气转化为替代天然气(SNG). VESTA甲烷化装置的安装已经完成,并将于2022年全面投入使用.
