一种新的微波热解系统瞄准了中国堆积如山的有毒污泥

你好，我是Innov8tia的Seth。感谢您阅读这篇文章并询问我们的系统。有几个方式，我们的R2S赞美AD和区分自己:1。我们专注于处理工业污泥和混合的部分腐蚀塑料，这些废物是不可回收的，通常是危险的，而且没有其他处理方法。厌氧消化最适合于食物垃圾、庭院垃圾、城市污泥、农场动物粪便等我们通常认为“安全且可堆肥”的垃圾。Innov8tia的R2S可以处理含有重金属、持久性有机化合物和其他工业有机化学品的废物，以及AD无法处理的不可生物降解化合物(塑料)，这些化合物由于潜在的中毒和坍塌或效率降低而无法处理。大多数AD减少了大约50%的质量，在这种污泥没有商业应用或仍然危险的情况下，我们可以处理它。我们也处理那些不能焚烧、焚烧成本太高(高水分含量、运输)、焚烧的环境/社会后果不可接受，或者地方政府不愿意放弃土地空间来建造大型焚烧厂或AD设施的垃圾。我们正在与中国的一家食品垃圾处理厂合作，处理他们产生的污泥，其中可能含有15-20%的塑料。有一篇有趣的论文研究了AD和热解的结合，并取得了积极的结果:当前和未来污水污泥对能源技术的环境和经济生命周期评估(Mills, 2013)。 2. We view large, high throughput facilities as a less efficient state in many cases. We've designed the R2S to be small but equally efficient, allowing the system to be installed at the source, where waste is generated - achieving the process results we want without the expense and carbon footprint of transportation. The R2S is sized to treat the amount of sludge generated by a single manufacturer (around 3 to 6 metric tons per day) up to a pipe fed centralized treatment facility in an industrial park (maybe 150 to 250 tpd). Similar tech from our same university's lab is being used to build what will be the largest single gasifier in the world, but in Innov8tia's case smaller = better. https://www.nottingham.ac.uk/news/pressreleases/2018/april/powering-china's-future-with-clean-coal-technology.aspx 3. Toxins, temp, and energy. We do not produce many toxins in the first place, trivalent Cr isn't converted to hexavalent Cr, we don't produce H2S, NOx/SOx, and if we do we can simultaneously remove it along with any Hg. We reform 100% of organic compounds into useful products, if there are biologically available toxins (most probably heavy metals) we can crank the temp up to produce a non leaching slag instead of char. Because of our microwave enhanced nickle based heterogeneous catalysts we can operate at lower temperatures, generally between 500 to 850 C, up to 1200 if we need to. From most sludge we produce around 70% (% mass) syngas (H2+CO, some CH4 and other hydrocarbons C2-C4, H2 content is up to 40% by volume) and 30% char, little to no oil. The gas has an energy content of around 13-19 MJ/kg depending on the sludge feedstock, we use this gas to run a CHP which provides the energy we need to run the system, overall parasitic loss is around 50%, which isn't bad. A microturbine or SOFC could also be used - in fact we're working with a SOFC startup here in Ningbo and would prefer fuel cells, once they are acceptable to both accountants and system operators.
