Gasification for power generation and methanol production
Thread Content
Let’s discuss what the processes involved in IGCC power generation using gasification for methanol production are, and what their advantages are Is it more energy-efficient to generate power using only IGCC, or to produce methanol while also generating power and thus saving energy?
IGCC power generation is more environmentally friendly.
For IGCC, the main limitation at present is that the process is too complex and the engineering costs are high. Compared to current power plants, their efficiency is not much higher. Moreover, power plant technology is also evolving; supercritical and ultra-supercritical power plants have now been developed, and these types of plants also have high efficiency. However, their systems are much simpler and easier to modify. The biggest advantage of IGCC today is its environmental benefits; it offers significant advantages in the removal of CO2 and H2S. Facilities that produce chemical products through IGCC technology already exist in Yankuang, Shandong. In terms of the process, a methanol production unit has been added between the gasification stage and power generation; as a result, the exhaust gases from the methanol synthesis reaction do not need to be recycled as in conventional methanol plants, but can be directly used to drive gas turbines for power generation.
The economic viability of generating electricity alone is problematic; producing methanol alongside it is a better option
