Economic Optimization of Green Methanol production by Coupling Wind Power Generation with Biomass Power Generation

Abstract

Reducing carbon emissions in the chemical industry is an important condition for achieving "carbon peaking and carbon neutralization". As an important basic chemical industry, methanol production process is still dominated by coal chemical industry. It is urgent to find a new path and explore a green methanol production process. Due to the volatility and intermittency of wind power or photovoltaic power generation, it is difficult to meet the demand for methanol production only by using new energy for power generation, and there is also a lack of carbon sources. Therefore, it can be considered to use biomass power generation and wind power or photovoltaic power generation for green methanol manufacturing. A green methanol production system coupled with wind power and biomass power generation and its economic optimal allocation method are established in this paper. Under the premise of multi energy flow stability constraints, the full life cycle cost of the coupled system is minimized. Based on a green methanol scene in Inner Mongolia, a simulation analysis model is established. The simulation analysis results show that the economic benefits can be improved and the system operation effect can be optimized through multi energy flow coupling.
