This massively updated and expanded fifth edition is the most complete, authoritative engineering treatment of the dehydration and gas purification processes used in industry today. Of great value to design and operations engineers, it gives practical process and equipment design descriptions, basic data, plant performance results, and other detailed information on gas purification processes and hardware. This latest edition incorporates all significant advances in the field since 1985.You will find major new chapters on the rapidly expanding technologies of nitrogen oxide control, with discussions of regulatory requirements and available processes; absorption in physical solvents, covering single component and mixed solvent systems; and membrane permeation, with emphasis on the gas purification applications of membrane units. In addition, new sections cover areas of strong current interest, particularly liquid hydrocarbon treating, Claus plant tail gas treating, thermal oxidation of volatile organic compounds, and sulfur scavenging processes.This volume brings you expanded coverage of alkanolamines for hydrogen sulfide and carbon dioxide removal, the removal and use of ammonia in gas purification, the use of alkaline salt solutions for acid gas removal, and the use of water to absorb gas impurities. The basic technologies and all significant advances in the following areas are thoroughly described: sulfur dioxide removal and recovery processes, processes for converting hydrogen sulfide to sulfur, liquid phase oxidation processes for hydrogen sulfide removal, the absorption of water vapor by dehydrating solutions, gas dehydration and purification by adsorption, and the catalytic and thermal conversion of gas impurities.

Army Sergeant Garret Drake is a Special Forces sniper who''s comfortable with his job. He takes care of bad guys and is good at it. While on a forced vacation in the Amazon, two events change his life forever. During a tour at a river-side village, he saves the life of a little girl about to be bitten by a deadly viper. The next evening while on a night hike, an accident leaves his life in peril from the toxin of a poison dart frog. Saved by the only medical person available--a local shaman--Garrett is left in a coma and is transported to America to recover. Accompanied by Naturalist Joan Sedona, she tells him the healing includes a gift from the healer. One he doesn''t want--the ability to heal virtually any illness and injury with a touch. This gift comes with rules. Rules that if disobeyed, are fatal. Garrett reluctantly begins healing and tries to maintain a low profile. Despite this, an Army Intelligence officer, learns of this amazing talent and has Garrett transferred to a bioweapons lab where he''s more a prisoner than participant. The experiment takes a dark turn when a black ops force, under false pretences led by Joan Sedona is sent to the Amazon to find the shaman who gave the healing ability to Garrett and extract the information. By any means necessary. While inside the lab, Garrett discovers Joan is in the Amazon and believes the black ops team may not leave witnesses behind. and that another experiment is underway, one with ominous repercussions.With the experiments taking a ghoulish turn, Garrett realizes his escape plan must also include a way to save Joan, nearly five thousand miles away in the remote Amazonian rain forest.
