Headway completes laboratory testing of new decarbonized substance

A few days ago, Headway Technology Group (Qingdao) Co., Ltd. completed laboratory testing of a new decarbonized substance. This substance can not only absorb carbon dioxide quickly and efficiently, but also make the separation of carbon dioxide easier, and its own activity is more durable. Under the condition of combined installation of Headway desulfurization system and decarbonization system, it can reduce the fuel cost of ships by about 25%. It is reported that the decarbonization device supporting the substance will be installed on the actual ship in August this year.

In recent years, with the continuous growth of world trade activities and international shipping volume, scientists in various fields around the world are using various methods to solve the problem of carbon dioxide emissions from ships. Among them, it is recognized that the most effective carbon reduction measure is to absorb carbon dioxide directly at the discharge port. At present, traditional industries mainly use ethanolamine (MEA) solution or dimethylethanolamine (DMEA) solution to absorb carbon dioxide. Although this process is widely used in decarbonization devices of major land power plants and refineries, there are still problems such as equipment volume. The disadvantages of large size, many processing steps, high energy consumption, volatile unstable components in MEA, poor solution activity, and short cycle life limit its further application in ocean-going ships.

The new decarbonization material is matched with the decarbonization system independently developed by Headway, which eliminates the MEA solution and DMEA solution used in the traditional decarbonization process, so that the ship carbon dioxide recovery no longer needs to consider the ammonia emission of the traditional decarbonization process, which greatly reduces the The energy required to absorb a unit mass of carbon dioxide. 

According to reports, compared with the traditional process and the carbon dioxide combination ratio of 2:1, the absorption ratio of this substance to carbon dioxide has reached 1:1.4. Applying it to the decarbonization device developed by Headway will greatly save installation space. And it can be installed separately, which saves about 38.5% of energy consumption compared with the traditional process. Under the condition of joint installation of Headway desulfurization system and decarbonization system, it can reduce the fuel cost of ships by about 25%. 

As a high-tech enterprise with scientific and technological innovation as its purpose, Headway will continue to adhere to the development vision of “creating high-end marine products and building an international marine brand”, providing partners with efficient and reliable marine products and technical service solutions, and providing shipping products for shipping. Contribute to the green, smart and sustainable development of the industry.

海德威完成新型脱碳物质实验室测试可降低25%船舶燃料成本

日前,海德威科技集团(青岛)有限公司完成了一种新型脱碳物质的实验室测试。该物质不仅能够快捷高效吸收二氧化碳,还可让二氧化碳分离变得更容易,自身活性更持久,在海德威脱硫系统和脱碳系统联合加装的工况下,可降低船舶燃料成本约25%。据悉,配套该物质的脱碳装置将于今年8月启动实船安装。

近年来,随着世界贸易活动和国际航运量的持续增长,全球各领域科学家都在通过各种方法来解决船舶二氧化碳的排放问题。其中,公认最有效的减碳措施就是直接在排放口进行二氧化碳吸收。当前,传统工业主要利用乙醇胺(MEA)溶液或二甲基乙醇胺(DMEA)溶液来吸收二氧化碳,这种工艺虽被广泛应用于陆地各大电厂和炼油厂的脱碳装置,但仍存在诸如设备体积大、处理环节繁多、能耗高、MEA中的不稳定成分易挥发、溶液活性差、循环寿命短等缺点,限制了其在远洋船舶上的进一步应用。

该新型脱碳物质搭配海德威自主研发的脱碳系统,淘汰了传统脱碳工艺所使用的MEA溶液和DMEA溶液,使船舶二氧化碳回收不再需要考虑传统脱碳工艺的氨排放,极大降低了吸收单位质量的二氧化碳所需能耗。

据介绍,相较传统工艺与二氧化碳结合比例为2:1,这一物质与二氧化碳的吸收比达到了1:1.4,将其应用于海德威研发的脱碳装置中,将极大节省安装空间,且能进行分体安装,比传统工艺节省约38.5%的能耗需求,在海德威脱硫系统和脱碳系统联合加装的工况下,可降低船舶燃料成本约25%。

作为一家以科技创新为宗旨的高新技术企业,海德威将持续秉承「创造高端船舶产品,打造船舶国际品牌」的发展愿景,为合作伙伴提供高效可靠的船配产品与技术服务解决方案,为航运业绿色、智慧、可持续发展贡献力量。
