1. Proj. Name：CPCT 3/4 E.F. H₂S Waste Sour Gas Emission Improvement Project

2. Client：CPC Tao-yuan Refinery

3. Proj. Period：April 2021∼Aug. 2022

4. Proj. Description：

This Project is for CPCT to reduce the H₂S waste sour gas in the 3/4 Elevate Flare Pipelines in accordance with the Self-Improvement requirements of air pollution prevention and control. Therefore, it is planned to add a Unit of waste sour gas Scrubbing Facilities within the limited area of 8Mx17M. By using new added Scrubbing Facilities, it is expected that the concentration of H₂S emission can be effectively reduced at least ≧95% in case of the Max. 3,000 Nm³/h waste sour gas flow rate with 41.2Vol% H₂S inlet content. Meanwhile, the other requirements of system pressure drop≦1,200mmH₂O, Dust removal≧50%, COD of effluent≦1,000 mg/L are also needed to be met.
