A Predictive Model For Uniaxial Compressive Strength Of Carbonate Rocks From Schmidt Hardness, Murat Yurdakul, Halil Ceylan, Hurriyet Akdas Jan 2011

A Predictive Model For Uniaxial Compressive Strength Of Carbonate Rocks From Schmidt Hardness, Murat Yurdakul, Halil Ceylan, Hurriyet Akdas

Civil, Construction and Environmental Engineering Conference Presentations and Proceedings

Uniaxial compressive strength (UCS) is considered to be one of the important parameters in rock engineering projects. In order to determine UCS, direct and indirect techniques are employed. In the direct approach, UCS is determined from the laboratory UCS test. In indirect techniques determine UCS based on the nondestructive test findings which can be easily and quickly performed and require relatively simple or no sample preparation. Indirect techniques are commonly preferred by rock and mining engineers because of their low cost and ease. This study presents the findings of an Artificial Neural Networks (ANN) based model for the prediction of ...


Resource Recovery From Wastewater Treatment Sludge Containing Gypsum, L.L. Smith, M.L. Fortney, C.E. Morris, Thomas D. Wheelock, J.A. Carrazza Jan 1984

Resource Recovery From Wastewater Treatment Sludge Containing Gypsum, L.L. Smith, M.L. Fortney, C.E. Morris, Thomas D. Wheelock, J.A. Carrazza

Chemical and Biological Engineering Conference Presentations and Proceedings

The disposal of wastewater treatment sludge generated at the Radford Army Ammunition Plant (RAAP) is a serious problem. The sludge is produced by neutralizing spent acid contained in the wastewater with lime, and consists principally of very finely divided wet gypsum (calcium sulfate dihydrate). Although the sludge is presently being disposed of in a landfill, the sludge is difficult to handle and convert into a load-bearing material. Therefore an alternative method of disposal is being developed and evaluated.

The alternative method involves drying and granulating the sludge, followed by high temperature calcination in a fluidized bed reactor to recover usable ...


Evaluation Of The Removal Of Organic Sulfur From Coal, R. Markuszewski, L.J. Miller, W.E. Straszheim, C.W. Fan, Thomas D. Wheelock, R.T. Greer Jan 1981

Evaluation Of The Removal Of Organic Sulfur From Coal, R. Markuszewski, L.J. Miller, W.E. Straszheim, C.W. Fan, Thomas D. Wheelock, R.T. Greer

Chemical and Biological Engineering Publications

As the removal of sulfur from coal prior to combustion acquires more importance in order to meet evermore stringent antipollution regulations, research on the development of methods for the cleaning of coal continues to expand. Reviews are available which describe the various methods for desulfurizing coal (1, 2, 3). The sulfur content in coal is usually a few per cent, but it can range from less than 0.5 per cent to as much as 8 per cent or more. Much of the sulfur is inorganic in nature, occurring in discrete mineral phases; the inorganic sulfur is mostly pyrite with ...
