Book Description
In conjunction with the work on interfacial area and contact time, an investigation was carried out to study the factors affecting mass transfer coefficients in vapor-liquid contacting. Measurements of point efficiency on the distillation of a systems of acetone and water determined both the liquid and vapor mass transfer coefficients under various operating conditions. The study was conducted on a 4" diameter column using the same type of single-slotted 1.5" diameter cap employed in the previous work. The range of physical properties and operating variables included: vapor rate: G=5000 to 25,000 lbs./sq.ft.(hr.); liquid rate: L=500 to 3,600 lbs./sq.ft.(hr.) ; vapor Reynolds number: 6400 to 24,100; liquid Reynolds number: 35 to 800 ; vapor Schmidt number: 0.27 to 0.42; liquid Schmidt number: 50 to 330. Both vapor and liquid mass transfer coefficients were correlated as "jD" factors, with their respective Reynolds numbers. The equations developed were: [....]. In combination with the results on interfacial area and contact time, a generalized correlation for point efficiency data reported in the literature (30,53) and found it to be in excellent agreement. Based upon analysis of this and other studies reported in the literature (21,22) an explanation of the mechanisms involved in bubble plate mass transfer operations was presented. Since the efficiencies measured in this study were uniformly high, even in the absence of a froth zone, it was indicated that a substantial portion of the mass transfer occurring on a bubble cap plate takes place in the bubble formation region.

Book Description
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.
