Assessment of carbon dioxide propagation in a pipeline emergency

Abstract

One of the most important problems of our time is the annual growth of greenhouse gas emissions into the atmosphere. To combat this phenomenon, emission reductions or the development and application of technologies for capturing, storing, using and utilizing carbon dioxide are possible. The need to implement projects for the decarbonization of technological processes is also relevant in connection with the international climate agenda. To reduce emissions, one cannot do without measures aimed at carbon sequestration. Of great interest is the creation and implementation of industrial carbon sequestration technologies that use the existing oil and gas infrastructure and allow obtaining additional benefits by increasing oil and gas recovery. The implementation of this technology largely depends on the environmental and economic feasibility of the project, which is influenced by the selected technologies for capturing and cleaning gas from impurities, the length of the pipeline to the field, a reasonable injection technology, and many other factors. For this reason, scientific and practical research in this direction are of practical importance and are quite relevant. The article presents the results of an analysis of the consequences of a violation of the tightness of a pipeline for pumping carbon dioxide. The calculation of the distribution zone of the release, as well as changes in the concentration in the flow, was carried out. The conclusion is made about the possibility of estimating the time required for the distribution of the carbon dioxide flow in the air volume to reduce its concentration to acceptable values. The work performed is important in terms of profile planning, location and safety measures in the construction and operation of pipelines for carbon dioxide transfer.
