Abstract：Carbon dioxide capture and storage(CCS)technology,as an important means to address global warming,has been widely adopted in China.However,during its promotion process,this technology faces challenges such as insufficient technical maturity,high investment costs,and potential environmental leakage risks.To address the safety challenges in the promotion of CCS technology,taking a 400 000 t/a CCS pilot project of a certain company as the research object,considering the safety requirements of ground capture,pipeline transportation,and underground storage,the hazard and operability study(HAZOP)method combined with the company's risk matrix is adopted to comprehensively assess the process parameters and equipment operation risks at the design stage from multiple dimensions,and improvement plans and measures are formulated for different risks.Specific HAZOP analysis results are obtained,and targeted intervention measures are proposed.The research results can provide references for the subsequent revision of operation procedures,formulation of employee training plans,and supplementation of hidden danger governance measures for the project.
