• Managing water consumption in mining

  With carbon capture, the difference in water use is even more dramatic (2.5:1.0), as the chemical absorption process for CO 2 capture in PC plants (amine) requires even more cooling water. In terms of raw water increase, CO 2 capture increases raw water use by 37% for IGCC plants, versus a 95% increase for PC plants.

• The Five Processes of Gasifiion ALL Power Labs

  Reduction is the direct reverse process of combustion. Combustion is the combination of combustible gases with oxygen to release heat, producing water vapor and carbon dioxide as waste products. Reduction is the removal of oxygen from these waste products at high temperature to produce combustable gases.
