生物质气化耦合绿氢制备绿色甲醇技术经济性分析
Techno-economic analysis of green methanol production via biomass gasification coupled with green hydrogen
摘要
Abstract
The production of green hydrogen using renewable energy to synthesize green methanol can solve the problem of renewable energy consumption and is also one of the important ways to reduce carbon dioxide emissions.In order to design a green methanol project and assess its technical and economic feasibility,a case study of a green methanol project in Northeast China was conducted.The technical route and process flow of biomass gasification coupled with renewable energy hydrogen production for green methanol synthesis were evaluated.Considering the volatility of renewable energy generation,time-period scheduling control was applied.With the goal of optimizing the project's economic performance,the real-time power balance method was simulated and matched,resulting in a hydrogen production capacity of 52000 m3/h for a 500 MW wind power installation.Additionally,the effective hydrogen storage capacity is 2210000 m3,and the green methanol production capacity is 160000 t/a.Under the given boundary conditions,internal rate of return(IRR),payback period,total return on investment,and net profit margin on equity were selected as the economic indicators.With a project financial IRR(after tax)of 6%,the green methanol price is calculated to be 5324.06 CNY/t.Additionally,the payback period(after tax)is 12.25 a,the financial IRR on equity is 11.91%,the total return on investment is 4.19%,and the net profit margin on equity is 12.59%.The project is economically viable.The proposed project plan is feasible,meets relevant standards and engineering requirements,and can provide a reference for future green methanol project design.关键词
