CoFlo tray Design and Technology Report

This report consists of two major segments. CoFlo Tray Design is the first section. The objectives of this section are: (1) Determine the design requirements for increased capacity by the substitution of CoFlo trays for sieve trays in a 15-tray 46-inch diameter column. The Design Basis was obtained from the Separations Research Program, which was solicited by an industrial customer on the use of CoFlo trays for their application. (2) Illustrate the design procedures so that they can be computerized to rapidly provide design and cost information for future customers. A summary of the research studies on which each design procedure is based is included. (3) Compare the costs of new sieve tray and CoFlo tray columns for this application to illustrate the savings inherent in the CoFlo process. Exhibits are the second section of this report and its objectives are to: (a) Report the extensive research studies on the CoFlo tray and related items; (b) Analyze present and potential future performance of the CoFlo tray; (c) Present comparative costs for sieve and CoFlo tray columns; and (d) List the applications for the CoFlo deentrainer
