Excerpt from A Manual of Chemical Plant It is no part of the author's plan, in compiling this manual, to enter into the question of the design of chemical works or the principles under lying the construction of chemical plant. That is the business of the chemical engineer, and for the theory of the subject the reader must be referred to the literature of chemical engineering. The task of the author is to present a record, at far greater length than is possible in any general chemical treatise, of the practical outcome of research and experiment as embodied in the range of plant which is actually avail able for the carrying out of the operations and processes of industrial chemistry, and the entire subject has been treated from this point of view. Especially is this the case with the pat-ent literature which has been dealt with. The examination of some thousands of specifications of patents relating to chemical plant and processes has inevitably resulted in the laying down of very sharp lines of demarcation between the purely theoretical patentee and the inventor whose improvements reach the stage of a commercially successful apparatus or process. The author's work for the last twenty years has been the recording of pro gress in chemical technology from this standpoint, and the present volume represents the fruit of his labours so far as chemical plant is concerned.
