Comparison of a regenerative thermal oxidizer to a rotary concentrator for gravure printer ketone emissions
- Durr Industries, Inc., Plymouth, MI (United States)
A large gravure printer was faced with choosing a control system to reduce ketone emissions. The volume of exhaust air requiring treatment was very large, making any system expensive to operate. The large system magnified the need to find the most cost-effective system including capital cost, operating cost, and periodic replacement cost. Future expandability and very high efficiency were required. Several proven control technologies were evaluated, including a recuperative oxidizer, a catalytic oxidizer, a stand-alone regenerative oxidizer, a rotary solvent concentrator, and a solvent recovery system. The most cost-effective system meeting the destruction requirements was achieved by integrating two technologies - a rotary solvent concentrator following by a small regenerative thermal oxidizer - into one unique and very flexible system. Operating costs used to evaluate each option are presented. Destruction and removal efficiency of the final system is presented. 3 figs., 4 tabs.
