Book Description
Lime is a white, powdery substance widely used in construction, agriculture, and industry. It is manufactured by heating limestone. Small amounts may be produced in an open fire but more effectively when enclosed. Early pits were lined with stone and in time enclosed in an oven or kiln. The 19th-century lime kiln, of Roman design, was a large "pot" dug into a hillside, surrounded by a stone box resembling a huge fireplace. Many thousands were built in the Susquehanna River valley. During settlement of "Penn's Woods," large tracts were subdivided many times, and by 1925 we find 12,000 farms in Lancaster County alone, and nearly every farmer wanted to produce his own lime to sweeten the fields and make mortar, plaster, and whitewash. In the most recent record, the 1875 county atlas, we find more than 500 kilns, a peak time for "do it yourself" lime burning. Commercialization relieved the farmer of the hard and dangerous work of lime burning, and the kilns fell idle around the turn of the century. Today we find evidence of 128 extant kilns in the county. Some are little more than remnants of former stonework, but others remain sturdy and sound. Their photos in this book reveal the art and labor of our ancestors who played a major role in the development of our nation.

Book Description
Pulp and Paper Industry: Chemical Recovery examines the scientific and technical advances that have been made in chemical recovery, including the very latest developments. It looks at general aspects of the chemical recovery process and its significance, black liquor evaporation, black liquor combustion, white liquor preparation, and lime reburning. The book also describes the technologies for chemical recovery of nonwood black liquor, as well as direct alkali regeneration systems in small pulp mills. In addition, it includes a discussion of alternative chemical recovery processes, i.e. alternative causticization and gasification processes, and the progress being made in the recovery of filler, coating color, and pigments. Furthermore, it discusses the utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor, including related environmental challenges. - Offers thorough and in-depth coverage of scientific and technical advances in chemical recovery in pulp making - Discusses alternative chemical recovery processes, i.e., alternative causticization and gasification processes - Covers the progress being made in the recovery of filler, coating color, and pigments - Examines utilization of new value streams (fuels and chemicals) from residuals and spent pulping liquor - Discusses environmental challenges (air emissions, mill closure) - Presents ways in which the economics, energy efficiency, and environmental protection associated with the recovery process can be improved
