二氧化碳气体井下远距离输送的可行性研究 Title: Feasibility Study of Long-Distance Underground Transportation of Carbon Dioxide Gas Introduction: With the increase in greenhouse gas emissions and the urgent need to reduce carbon dioxide (CO2) levels in the atmosphere, the transportation and storage of CO2 have become crucial challenges. One potential solution is the underground long-distance transportation of CO2 gas. This paper aims to investigate the feasibility of this transportation method, including its technical, economic, and environmental aspects. 1. Technical Feasibility: 1.1 Transport Process: The transportation of CO2 gas would involve capturing the gas at its source, compressing it to asupercritical state, and injecting it into underground pipelines or wells. 1.2 Pipeline Design: The design and construction of pipelines or wells for CO2 transport should consider factors such as pressure, temperature, and CO2 purity. The potential risks of leaks and corrosion must also be addressed. 1.3 Safety Considerations: An effective monitoring and control system should be implemented to ensure the safe transportation of CO2 gas. Emergency response plans should be developed in case of leakages or accidents. 2. Economic Feasibility: 2.1 Initial Investment: Building aCO2 transportation network would require significant upfront costs, including the construction of pipelines, compression equipment, and monitoring systems. 2.2 Operation and Maintenance: The operational expenses of the transportation system, including monitoring, maintenance, and security measures, should be considered. 2.3 Cost Comparison: The cost-effectiveness of long-distance underground transportation should be compared with alternative methods such as trucking, rail, or shipping. Factors such as energy consumption, labor costs, and infrastructure requirements should be evaluated. 3. Environmental Feasibility: 3.1 Climate Benefits: Underground transportation can facilitate the capture and storage of CO2, reducing its release into the atmosphere and mitigating climate change. 3.2 Environmental Impact: The potential risks associated with underground CO2 transportation, such as leakage, must be thoroughly assessed to protect groundwater and avoid negative environmental consequences.
