Control of Blackwater in Coal Preparation Plant Recycle and
Water recycle is an important part of the coal preparation process. This study was directed toward (1) a survey of current practice and an evaluation of both the solid and liquid components of blackwater, (2) an experimental study of blackwater flocculation, and (3) a fundamental analysis of the flocculation process.
GypsumLimestone: two great soil amendments with key
2014年7月18日In coal-fired power plants, lime removes sulfur oxides from flue gas, forming calcium sulfate, or gypsum. And the higher the sulfur content of the coal, the greater the amount of synthetic gypsum produced. This form of gypsum creates a disposal issue for power plant operators, and finding uses for it has been an ongoing process.

Gypsum as an agricultural product Soil Science Society of
2019年2月6日Improving soil structure helps farmers with some common agricultural problems. Adding gypsum to the soil reduces erosion by increasing the ability of soil to soak up water after precipitation, thus reducing runoff. Gypsum application also improves soil aeration and water percolation through the soil profile.
