Eli Lilly USA: High Efficiency Incinerator Scrubber - Case Study
Problem: How to meet the MACT emission standards at the Eli Lilly plant.
Solution
In 2002 Eli Lilly ordered two TurboScrubber® units from Osprey Corporation installed in series on the outlet of pharmaceutical waste incinerators in Clinton, Indiana. The upstream TS “C/A” unit was for condensing & absorbing of multiple acid gases plus removal of fine particulates using only water & the downstream TS “P/S” or polisher unit was required to perform high efficiency absorption of the cocktail of acid gases using NaOH dosing. Since meeting MACT emission standards was a must for the system & given the very high loadings plant engineers RMT requested the addition of a non absorbing high energy (60” WG) Venturi stage for additional PM removal which could have been handled with far less energy consumption & Capex by increasing the TurboScrubbers’ pressure drops (via L/G & fluid be height increases).
Results
The resultant performance was perfect performance form the improved plant.
