Excerpt from American Sulphuric Acid Practice During a period of several years in close contact with the manufacture of Sulphuric Acid the writers have a great many times been asked to recommend some published work upon the subject from which a knowledge of the practical essentials of modern American acid making could be obtained. This inquiry has come from men working in association with, and under the supervision of, the writers, and also from men in allied lines who wished to acquaint themselves quickly with this information. SO far as the writers know, such a work in English does not exist. Lunge's Sulphuric Acid and Alkali is admirable in many ways, and certainly every one permanently connected with the manufacture of acid should have it for reference: it does not, however, cover modern American practice, nor is it suitable to present to a new chamber Operator as a source of information. Besides Lunge, there are several books which include a few chapters on sulphuric acid, but none is satisfying. The writers' purpose in preparing this volume has been to provide some fundamental information for the man with little preliminary knowledge of the subject. It does not in any way pretend to cover acid manufacture with the thoroughness of Lunge. History, chemical and physical theory, and many other things are treated from the technical, not the scientific, view-point, in an effort to avoid the error, so common in Handbooks, of not devoting much time to Why, while very thoroughly covering How. Note. Sullivan's Handbook so thoroughly covers the laboratory end that We have not included laboratory practice, and recommend his methods. The writers are much indebted to several manufacturers of acid plant equipment for photographs and drawings of machinery and apparatus.
