Absorption Of Carbon Dioxide In A Bubble Plate Tower, William Arthur Enderson
Absorption Of Carbon Dioxide In A Bubble Plate Tower, William Arthur Enderson
Masters Theses
"Gas absorption, one of the chief operations of chemical engineering, has occupied investigators for a long time. Results of many experiments on the general subject of gas absorption has been published. However, relatively few data have appeared in the literature on the use of bubble cap towers for gas absorption although they constitute one of the three major classifications of absorption equipment. Bubble cap towers are used extensively in the petroleum industry. More performance data would increase the versatility of existing equipment"--Introduction, page 1.
The Effect Of Addition Agents In Grinding Portland Cement Clinker, Eugene Farrell Hill
The Effect Of Addition Agents In Grinding Portland Cement Clinker, Eugene Farrell Hill
Masters Theses
"In the dry grinding of most materials in a ball mill or similar apparatus, a degree of fineness is eventually reached when a noticeable decrease in the efficiency of grinding occurs. The degree of fineness where this phenomenon occurs, as measured by the specific surface of the material being ground, varies greatly with different materials. The accompanying effect in all cases, however, is the formation of a coating upon the balls; this coating in the case of cement adheres tightly to the balls and increases in thickness as grinding progresses after the initial "coating' fineness has been reached. Usually an …
