摘要

利用可再生能源制氢合成绿色甲醇可解决绿电消纳问题，也是二氧化碳减排的重要途径之一。为开展绿色甲醇项目方案设计，并评估项目的技术经济可行性，以东北某绿色甲醇项目为例，对生物质气化耦合绿氢制备绿色甲醇的技术路线和工艺流程开展了论证。结合新能源发电的波动性，分时段调度控制，以项目经济性最优为目标，通过实时电量平衡法模拟匹配，获得了500 MW风电装机规模下的制氢规模为52000 m

/h，有效储氢规模为221 × 10

，绿色甲醇规模为160000 t/a。在给定边界条件下，选取内部收益率、投资回收期、总投资收益率和资本金净利润率作为经济性指标。按照项目投资财务内部收益率（所得税后）为6%，反算绿色甲醇售价为5324.06 CNY/t，项目投资回收期（所得税后）为12.25 a，资本金财务内部收益率为11.91%，总投资收益率为4.19%，项目资本金净利润率为12.59%，项目在经济上合理可行。本研究所提项目方案具备一定可行性，满足相关标准及工程要求，可为后续绿色甲醇项目方案设计提供参考。

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 used to simulate and match

resulting in a hydrogen production capacity of 52000 m³/h for a 500 MW wind power installation. Additionally

the effective hydrogen storage capacity is 221 × 10

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 meth

anol project design.
