美国一初创公司称可使水泥行业完全脱碳

2023-10-19 14:44:46

Brimstone 使用比石灰石更丰富的硅酸钙岩石,并使用专利技术剥离钙。然而,与石灰石不同的是,硅酸盐岩石不含二氧化碳,因此生产过程中不存在此类排放。

当今大多数建筑环境至少部分由混凝土制成,使其成为地球上仅次于水的第二大使用材料。但制造混凝土排放的二氧化碳几乎与汽车一样多,因为其主要成分水泥是由石灰石制成的。石灰石天然含有按重量计约50%的二氧化碳。

Brimstone Energy 是一家总部位于加州的初创公司,是致力于减少水泥生产过程中的碳排放的公司之一。

Brimstone 使用比石灰石更丰富的硅酸钙岩石,并使用专利技术剥离钙。然而,与石灰石不同的是,硅酸盐岩石不含二氧化碳,因此生产过程中不存在此类排放。去年7月,该公司获得认证,证明其产品与水泥本质上相同。

Brimstone 联合创始人兼首席执行官科迪·芬克 (Cody Finke) 表示:“人们已经知道如何使用它进行建造,因此施工不会被延误,也不会存在安全问题。”

该公司仍处于早期阶段,目前正在建设一座试点工厂,但芬克表示,一旦规模扩大,生产水泥的成本将比现在低。

“最终,我们的计划、目标是开发一种可靠的低成本工艺来大规模生产水泥。因此,由于成本较低,我们的工艺最终将取代全球100%的水泥生产设施,从而一个完全脱碳的系统,”芬克说。

改变水泥制造方式的目标对投资者尤其有吸引力。

“当今地球上大约有3000座水泥厂终将开始用这种新颖工艺取代旧工艺,这实际上蕴含了数万亿美元的固定资产投资潜力,所有这些都是由利润激励驱动的。”Brimstone 的支持者之一、Breakthrough Energy Ventures 的库珀·林兹勒 (Cooper Rinzler) 说道。

除了 Breakthrough 之外,Brimstone 的投资者还包括 DCVC、Collaborative Fund、Fifth Wall、S2G Ventures 和亚马逊的 Climate Pledge Fund。该公司迄今已筹集 6000 万美元。

Wanbei Cement "High Temperature and Low Dust SCR Dust and Nitrate Integration" project adopts the international advanced SCR denitrification technology, combines with the innovative technology of high temperature and low dust, and reduces the dust concentration to less than 10 mg/Nm ³ by setting a high temperature metal bag filter in front of the SCR reactor, which effectively solves the problem of high dust content in the flue gas at the end of the cement furnace. Clean gas enters the catalyst reaction layer to ensure that the catalyst operates in a high-temperature micro-dust state, thereby realizing the integrated continuous removal of dust and nitrate.
