From the preface:"THE purpose of this work is to make the reader better acquainted with that wild land which he has known from childhood, as the home of the Indian and the buffalo. The Rocky Mountain chain, distorted and rugged, has been aptly called the colossal vertebrae of our continent's broad back, and from thence, as a line, the plains, weird and wonderful, stretch eastward through Colorado, and embrace the entire western half of Kansas.Fortune, not long since, threw in my way an invitation, which I gladly accepted, to join a semi-scientific party, since somewhat known to fame through various articles in the newspaper press, in a sojourn of several months on the great plains. At a meeting held with due solemnity on the eve of starting, the Professor (to whom the reader will be introduced in the proper connection) was chosen leader of the expedition, while to my lot fell the office of editor of the future record, or rather Grand Scribe of what we were pleased to call our "Log Book." The latter now lies before me, in all its glory of shabby covers and dirty pages. Its soiled face is as honorable as that of the laborer who comes from his task in a well harvested field. Out of the sheaves gathered during our journey, I shall try and take such portions as may best supply the mental cravings of the countless thousands who hunger for the life and the lore of the far West.I have given the mistakes as well as triumphs of our expedition, and the members of the party will readily recognize their familiar camp names. The disguise will probably be pleasant, as few like to see their failures on public parade, preferring rather to leave these in barracks, and let their successes only appear at review."
Vapour permeation and membrane distillation are two emerging membrane technologies for the production of vapour as permeate, which, in addition to well-established pervaporation technology, are of increasing interest to academia and industry. As efficient separation and concentration processes, they have high potential for use in the energy, water, chemical, food and pharmaceutical sectors.
Part One begins by covering the fundamentals, preparation and characterization of pervaporation, before going on to outline the associated systems and applications. State of the art uses, future trends and next generation pervaporation are then discussed. Part Two then explores the preparation, characterization, systems and applications of membranes for vapour permeation, followed by modelling and the new generation of vapour permeation membranes. Finally, Part Three outlines the fundamentals of membrane distillation and its applications in integrated systems, before the book concludes with a view of the next generation.
