Coal - Carbon Dioxide (CO2) Slurry Feeding System for Pressurized Gasifiers
Performer: Massachusetts Institute of Technology
Project No: FE0012500
This MIT project will develop and assess a slurry feeding system based on a suspension of coal in liquid CO2 that can be pumped into a high-pressure gasifier. The advantages of this solution are that CO2 has a low heat capacity, a low heat of vaporization and low viscosity. Thus, the liquid CO2 imposes a much smaller thermal load on the gasifier relative to a water slurry, and has the potential to improve the efficiency and economics of integrated gasification combined cycle (IGCC) power plants with carbon capture and dramatically reduce greenhouse gas emissions from coal fired power plants.
