Clean Coal Explained What Is Clean Coal? Popular Mechanics
The term clean coal has been applied to many technologies, ranging from wet scrubbers, which remove sulfur dioxide There are a range of different clean coal methods, devices and technologies Some have been used for years, whilst others are new or still under development, and might be more speculative or unproven They can be used at different stages of the coal energy process at the mining stage (such as washing coal), at the coal power plant stage (such asClean Coal: What Is It, Is It Really 'Clean' & Eco Friendly,
