4 UNDERGROUND COAL GASIFICATION–ADVANTAGES COAL GASIFICATION •Tapping energy from vast coal reserves which are not commercially viable to mine

Gasification may occur in a separate processing facility or a coal mine. The gases can be stored or burned for the production of electricity, fuel or chemicals. Gasification usually involves the use of oxygen and steam. This process offers several advantages and disadvantages with regard to efficiency, cost, the environment and other factors.

Gasification has inherent advantages over combustion for emissions control. Emission control is simpler in gasification than in combustion because the produced syngas in gasification is at higher temperature and pressure than the exhaust gases produced in …

The Cons of Coal Gasification. The gasification of coal may also draw a number of disadvantages. These disadvantages primarily include the following: 1. The drawbacks of coal gasification are quite substantial. When gasification has been taken off, there will be no sufficient waste coal within the country to sustain the beast.

May 02, 2009· The Pros and Cons of Coal Gasification As we have learned in class, of the natural fossil fuels we have at our disposal, coal is pretty much the left handed, red headed step child of the group. It's the dirtiest, the hardest to harvest, and has less energy per kg than our other options, but it does have one thing going for it: it's really plentiful.

Coal - Advantages and Disadvantages Regardless of which source of energy it is, we need to take its advantages and disadvantages into consideration to determine whether it is a reliable or not.
