Description
Technical Field
The invention belongs to the technical field of metal corrosion experiments, and particularly relates to a test device and a test method for simulating corrosion of a supercritical carbon dioxide conveying pipeline.
Background
In recent years, energy supply and climate change have become key issues that restrict global economic development. In particular, the excessive emission of greenhouse gases causes global warming, and the economic construction and the life of people are seriously influenced. CCUS (short for Carbon capture, atomization and storage) is a mainstream technology for dealing with Carbon emission and greenhouse effect internationally, including Carbon capture, utilization and sequestration. Specifically, the CCUS separates carbon dioxide from industrial or other emissions sources, such as power plants, coal gasification, etc., concentrates, compresses, transports to a specific location, injects into a reservoir for sequestration to achieve long-term separation of the captured carbon dioxide from the atmosphere. According to the estimation of the international energy organization, the CCUS technology is expected to reduce more than 20% of carbon emission on the global scale.
In China, the emission reduction task of greenhouse gases in high-emission industries such as coal chemical industry, steel, cement and the like is heavy, so that the CCUS technology has a very wide application prospect. In addition, in the oil and gas industry, the technical practice of carbon dioxide flooding to improve the recovery ratio is also popularized and applied. Therefore, the CCUS technology has very important significance for coping with climate change and promoting low-carbon development in China for a medium and long time.
Nevertheless, the problem of corrosion of metal pipes by carbon dioxide is not negligible. In particular, the corrosion problem of metal pipelines is endless in the process of conveying and injection-production of supercritical carbon dioxide. In addition, the content of impurities varies depending on the carbon dioxide source, and the influence of impurities on corrosion is complicated. This is a major problem currently affecting the development of the CCUS technology.
By supercritical carbon dioxide, it is meant pure carbon dioxide in a stable single phase at pressures and temperatures exceeding its critical values (7.38MPa, 31.4 ℃), which has some unique properties, such as density close to that of a liquid, low viscosity, high diffusion coefficient, etc. These unique properties make the corrosion mechanism for metal pipes different from the common carbon dioxide corrosion. Therefore, research on corrosion of supercritical carbon dioxide has received attention from numerous scholars. Subject to the structural and functional limitations of conventional reactors, there are two so-called "supercritical carbon dioxide" environments that are common today: one is to soak the sample in the solution and then introduce carbon dioxide to make it exceed the temperature and pressure of the critical point; another is to suspend the sample above the solution and introduce carbon dioxide to exceed the critical temperature and pressure. The first environment is far from the service environment of the supercritical carbon dioxide conveying pipeline, and the corrosion is relatively serious because the sample is immersed in the solution. The second environment is relatively close to the service environment of the supercritical carbon dioxide conveying pipeline, but has two problems: the problem of carbon dioxide consumption in a sealed environment is solved, and the problem that the water content in the carbon dioxide cannot be effectively and definitely controlled is solved. Therefore, the test rule obtained by the two simulation environments cannot effectively represent the service condition of the supercritical carbon dioxide conveying pipeline, and the large deviation of the test rule can even lead to the invalidation of the test result.
