SLIDE 25 The wet lime slurry scrubber, built at EERC, meets the Carbozyme Acceptance Standard
– EERC CEPS fired on SO2 spiked natural gas to low, moderate, and high levels - 860, 2600 & 3300 ppmv – Pollution Control System on CEPS = SCR, Fabric Filter, Wet Scrubber 1, Polishing Scrubber (CaCO3 slurry)
Target - <7ppmv (20ppmw) - Required Performance Achieved
Lime slurry and ceramic Intalox saddle packing for the polishing
- scrubber. Packed tower used due to
small scale of the test unit.
