Research on Material Selection of Liquid Carbon Dioxide Storage Tank for Marine Carbon Capture System
With the increasingly strict requirements for carbon reduction in the international shipping industry,marine carbon capture technology has received widespread attention from the industry and has broad market prospects.Because the three-phase temperature of carbon dioxide is-56.56℃,liquid storage typically uses methods such as low temperature low pressure,and low temperature medium pressure.The article compares and analyzes different design schemes of liquid carbon C-type dioxide storage tanks,and obtains the most reasonable scheme.The results show that due to the lowest material cost,the material cost of low-temperature carbon steel,such as 16MnDR/P355NL1,storage tanks is the lowest.Low-temperature high-strength steel,such as P690QL1/P690QL2,storage tanks can significantly reduce the weight of the storage tanks,compared to other materials.Considering the weight and material cost of the storage tank,low-temperature high-strength steel such as P690QL1/P690QL2 should be used.
