Zipfel ZIPEEL PPD-SPD 304-863-2567 ( LEBAJ AT Al AT ESVAX } ( RAWLINGP AT ENGG AT MRGATE ) Subject: Summary of test at Exp Sta Gentlemen, here is my view of the test summary. TEST SUMMARY A six in dia column was setup foaming (flooding) at the C-8 experimental station to study the affects concentration, column temperature, and gas of column rate. This test work .vs. examined the following ranges: Air flow - 36.5-52.6 ACFM Temperature - 30-55oC C-B Cone - 500-2000 pptn. The results of concentration, the test showed that increasing gas flow, foaming increased with increasing C-8 and increasing temperature. The.first two concl incre us as i i o n ns g t were empe expect rature. e d, Th i b s ut l a i t t t e w r a s r e hope sult d i that ndic a f t o e aming s tha t would foam i b n e g reduced is more by dependent on support that surface tension rather than bubble increasing temperatures in the C-8 collapse. These data do not recovery scrubbers reduce column foaming. Complete test details are to be published in the Corporate Process Developement & Small Lots Manufacturing March, 1994, monthly report- Tour comments, Roger. o o 6 ^ Gt EID932208
