Typical Two Stage Odour Control System Using Q-PAC

Design Example 85 000 M³/hr, 99%+ Efficiency

= Low Operational Expense
= Effective Odour Control
= Reduced Chemical Losses
= Resistance to Fouling
= Reduced Maintenance, Long Service Life

Introduced to the industry in 1996, Q-PAC? offers a number of advantages when designing an odour control wet scrubbing system:

Q-PAC? for H₂S Odour Control Scrubbers

Never-the-less, there are losses of chemicals which cannot be prevented, which of course raise the cost of odour control scrubbing. These losses are due to the facts that bleach, NaOCl, slowly decomposes in storage as well as the fact that some amount of caustic is constantly lost to CO₂ absorption in both scrubbing stages.

The use of two stage scrubbing is often employed both to minimize chemical consumption as well as to control sulfur deposits when scrubbing H₂S. The first stage operates at
