PREFACE

This chapter on adsorption is the first completely new chapter added to the Technical Data Book-Petroleum Refining since its first edition. The Technical Data Committee felt that the use of physical adsorption for separations, the technical advances that have been made in the area of adsorption, and the lack of sources of practical design information on adsorption were justification for addition of this new chapter. During the past 2 years an extensive data bank on the physical adsorption equilibria of gases and liquids on solids has been collected, and potentially useful correlations have been evaluated with this data bank. Whenever possible, recommended procedures are given in the chapter for correlating or predicting equilibria data. In addition, bibliographies of available data and recommended references for studying the treatment of adsorption data are given. This chapter deals only with physical adsorption. Chemical adsorption is not considered.

Detailed results of the evaluations used in selecting the recommended procedures are given in Documentation Report No. 15-83, available from University Microfilms, Ann Arbor, Michigan.

Work on this chapter was done by S. D. Mehta and the project directors, Ronald P. Danner and Thomas E. Daubert. The chapter coordinator for the Technical Data Committee was G. E. Merritt, Arco Petroleum Products Company. Many other members of the committee contributed useful suggestions.
