Case Study: Clean Coal ~ Answer these questions
1. Describe IGCC and its importance: Integrated gasification combined cycle (IGCC). Power plants
could generate electricity while capturing and permanently storing carbon dioxide and other
pollutants.
2. Where is this currently taking place? Polk Power Plant in Tampa, Florida (approximately 1 year)
3. Is the coal actually being burned? How is the energy being generated.
No, it is not being burned. The coal is converted into a gas and the gas is burned in a turbine. Coal is
ground into a fine powder and mixed w/water to create a slurry. Slurry is pumped at high pressure
into a gasification chamber, where it mixes w/96% pure oxygen and heated to 1370 degreesC
(2500oF). Coal reacts w/O2 and breaks down into a variety of gases, mostly hydrogen and carbon
dioxide. Gases are cooled separately and converted into managed forms. From the turbine are fed
After purification, the synthetic hydrogen gas (syngas) is pumped to the combustion chamber, which
spins a large magnet to produce electricity. Superheated gases from the turbine are fed into a steam
generator that drives another turbine to produce more electrical energy. Combining these two
turbines makes an IGCC about 15% more efficient than a normal coal-fed powerplant.
4. How are the contaminants such as sulfur dioxide, ash and mercury which are generated from the
coal technology reduced/eliminated?
Sulfur dioxide, ash and mercury that normally go up in smoke in a normal coal-burning powerplant
are captured and sold to make the IGCC’s cleaner & economical. Sulfur is marketed as fertilizer, ash
and slag are sold to cement companies. Mercury removal is an important component of this system.
All slurry water is recycled to the gasifier; there is no waste water and very little solid waste.
5. State the advantages of this technology: Clean coal technology, less contaminated water,
recycling of materials such as mercury, slag, ash and sulfur. It is 15% more efficient than a normal
coal-fired powerplant.
6. State the disadvantages of this technology: Costs more to build an IGCC powerplant (by 15-20%
more) than a conventional coal-fired powerplant, digging the coal from strip or underground mines
has high environmental ramifications.
