摘要:
【目的】碳的捕集、利用与封存（Carbon Capture Utilization and Storage，CCUS）是减少大气中二氧化碳含量的关键技术之一，超临界/密相态CO2管道运输是将CO2从捕集点输送至封存点最经济、可行的方法。对于超临界/密相CO2的管道设计来说，关键要求是管道产生裂纹后阻止管道的长程韧性断裂，全尺寸爆破试验是目前验证管道在发生爆裂时能否停止断裂的最直接手段。【方法】据调研，国外共开展了11次全尺寸爆破试验，但考虑到国内外制管工艺的差异性以及实际CO2运输的不同情况，为探究中国超临界CO2管道的止裂韧性，成功开展中国首次全尺寸二氧化碳管道爆破试验，采用X65钢级、外径为323.9 mm、壁厚为7.2~7.6 mm的焊管进行试验，试验气体的组成为95%CO2+4%N2+1%H2，试验压力为11.85 MPa，温度为12.6 ℃。【结果】试验结果表明：CO2管道全尺寸爆破试验进展顺利，管道从起裂管开始裂纹扩展，在起爆位置西侧在两根管道的环焊缝处环切止裂，在起爆位置东侧由于管道母材韧性止裂，试验钢管表现为典型的韧性剪切断裂特征，且采集到裂纹扩展速度、压力及温度等多项重要试验数据。【结论】该试验为中国掌握百万吨级二氧化碳输送管材研制、管道设计及建设技术提供了重要的数据支撑，标志着中国在CCUS技术研究领域取得重要的突破性进展。
Abstract:
Carbon Capture, Utilization and Storage (CCUS) is one of the key technologies to reduce the amount of carbon dioxide in the atmosphere, and supercritical/dense-phase CO2 pipeline transportation is the most economical and feasible way to transport CO2 from the capture point to the storage point. The construction of CO2 pipeline in China is still in the initial stage, and there is an urgent need to accelerate the key core technology of CO2 pipeline transportation. For supercritical/dense phase CO2 pipeline design, the key requirement is to stop the pipeline cracks after the pipeline to prevent the pipeline's long-range toughness fracture, full-scale burst test is the current verification of the pipeline in the event of fracturing can arrest of the most direct means. Eleven full-scale burst tests have been carried out abroad, but taking into account the differences in the domestic and foreign pipe making process and the different situations of actual CO2 transportation, in order to explore the crack arresting toughness of supercritical CO2 pipelines in China, the first full-scale CO2 pipeline burst test was carried out in China. The test was carried out using a welded pipe of X65 steel with a diameter of 323.9 mm and a wall thickness of 7.2~7.6 mm. The test gas was 95% CO2+4% N2+1% H2, and the test pressure was 11.85 MPa and the temperature was 12.6 °C. The test results show that the full-scale burst test of CO2 pipeline progresses successfully, the pipeline starts crack propagation from the crack initiating pipe, the west side arrests by ring-cutting at the weld of the two pipelines, and the east side arrests due to the toughness of pipeline, the test steel pipe exhibits typical toughness shear fracture characteristics, and many important experimental data such as crack propagation speed, pressure and temperature were collected. This test provides important data support for China to master the development of million-ton CO2 transport pipe, pipeline design and construction technology, marking an important breakthrough in the field of CCUS technology research in China.
