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.
