High-Carbonate, Low-Silica, High-Calcium Stone In The High Bridge Group (Upper Ordovician), Mason County, North-Central Kentucky, Warren H. Anderson, Lance S. Barron

Information Circular--KGS

The High Bridge Group (Middle Ordovician) of northeastern Kentucky is a major source of limestone and dolomite for construction, agricultural, and industrial stone. These industries require carbonate rocks of high chemical purity. Chemical analyses of foot-by-foot samples from a Mason County core show that three zones of high-calcium and several thick zones of high-carbonate and low-silica stone are present in the High Bridge at a mineable depth. Mason County is located in northeastern Kentucky, on the Ohio River, and offers river access to transportation to the metropolitan Covington-Cincinnati market and the northern portion of the Eastern Kentucky Coal Field for …

Limestone And Lime For So2 And Pollutant Control In The Ohio Valley, James C. Cobb, Garland R. Dever Jr.

Information Circular--KGS

The purpose of this conference is to emphasize the importance of limestone resources for controlling SO₂ emissions from coal-fired power plants. We have brought together experts from utilities to describe important factors in limestone performance in scrubbers and from the stone industry to describe important factors in limestone and lime production. Conference speakers include also representatives from research institutes, equipment manufacturers, government agencies, and geological surveys.

Use Of Limestone, Lime, And Dolomite For So2 Emission Control In Kentucky, Garland R. Dever Jr.

Information Circular--KGS

Flue-gas desulfurization and atmospheric fluidized-bed combustion systems for sulfur dioxide (SO₂) emission control have been installed at 13 coal- and gas-fired plants and one research laboratory in Kentucky. Limestone, lime, and dolomite are the principal SO₂ sorbents used in these systems.

Nine coal-fired, electricity-generating plants in the State have installed wet-scrubbing systems for flue-gas desulfurization. Lime-based scrubbers are using Thiosorbic® lime, produced from the Camp Nelson Limestone (Ordovician) of north-central Kentucky, and carbide lime, a byproduct from the manufacture of acetylene in Louisville. Limestone-based scrubbing systems at three of the plants have used stone from the Warsaw, …
