DSP-13 Mixed Packing Test Expected Benefit toMembers: Improved performance of packed towers by retrofitting with mixed beds and improved new tower design. Present Situation and Proposed Research: The concept of using mixed beds of random packing has been proposed and touted as providing the pressure drop performance of the large packing and the efficiency of the smaller. Patents have been issued in the area and would need to be explored before proceeding. A test of the concept at SRP has been reported, but the results have not been widely used. Proposal Conduct a patent review to ensure the members can use any experimental work. Test a mixed bed of two sizes of Pall rings and compare against prior tests of those two sizes. Proposed Internals and Test System: Standard. Estimated Additional Costs (Beyond Unit Time): Unknown Estimated Unit Time: Total column time of six weeks as follows: • One week for initial installation • Two weeks’ operation with the first mixed bed • One week to install a bed with different percentages of the two sizes Two weeks’ operation with the second mixed bed Background and Discussion: The basics of this concept were originally developed by Belko, and patents related to the concept were issued to Belko and later transferred to AMACS. A test was conducted at SRP and appeared to be successful, but has not been widely accepted within the membership. An independent test at FRI would provide a credible gauge of the concept.
