Case Study
Medical Waste Incinerator CO Removal — Field Test
Field test of CO oxidation catalyst performance on a medical waste pyrolysis / incineration exhaust stream.
CO: 11,224.2 mg/Nm³ → 16.2 mg/Nm³
Reported result
The original field test record reports CO concentration reduced from 11,224.2 mg/Nm³ to 16.2 mg/Nm³ on 2023-03-20.
Data completeness note
For full engineering evaluation, the following data should be attached to the original record:
- Gas flow rate
- Operating temperature
- Oxygen content
- Continuous operating time
- Detection method and instrument
What this case demonstrates
The test shows high CO conversion on a fluctuating incineration stream — evidence of the catalyst’s tolerance to thermal cycling and multi-pollutant conditions.
Engineering takeaways
The reported field data — CO reduced from 11,224.2 mg/Nm³ to 16.2 mg/Nm³ on 2023-03-20 — was measured on a medical waste incinerator, a stream that also carries HCl, SO₂, heavy metals and moisture. Catalyst survival in this duty depends on the upstream gas cleaning: the acid and particulate removal stages protect the catalyst from rapid poisoning and blinding.
For a permanent installation, the follow-up questions are the operating temperature at the catalyst position, the CO spike behaviour during batch charging, and the expected chloride exposure — all of which set the deactivation margin in the sizing calculation.
