BOX ISO PLAQUEMINE, LOUISIANA 70765-0160 B04 388-8000 Boyd Horton Chairman Reactive Chemicals Committee WASTE HCL/SLUDGE ACIDIFICATION REVIEW Upon start-up of the Waste HC1 Utilization Project at Chlorine, the vapor space in T-29 will be analyzed for acetylene buildup. This data will be used as a baseline. Plans are to install a nitrogen purge as a precaution regardless of the acetylene analysis results. These actions are a result of the Reactive Chemicals Review Committee recommendations.

Check the vapor space in T-29 for acetylene buildup to make sure that there is no accumulation from dissolved gas in the Division aqueous acid system. 2. Consider use of a nitrogen or air purge on T-29 to prevent accumulation of chlorine or acetylene. NOTE: Please send a written response to the Chairman of the Reactive Chemicals Committee within two weeks as to action or planned action in regard to these considerations. W. B.
