1. Proj. Name：CPC Talin Refinery SRU#4 Sulfur Oxide Scrubber Project

2. Client：Talin Refinery of CPC Corp., Taiwan

3. Proj. Period：July 2024∼Otc. 2025

4. Proj. Description：

This project is for CPC-TL to reduce SRU #4 Tail Gas SO₂ emission by adding a SO₂ absorption Unit of caustic Scrubbing Facilities between the existing Catalytic Incinerator (R-4362) and Stack (M-4363) within the very narrow & limited available site space. Based on SRU #4 Tail Gas Inlet/Outlet Design Baselines for the new Scrubbing Facilities, it is expected that：Capacity in tail gas flow rate of 10,906 Nm³/h Max. w/ 1.2 Vol% SO₂ concentration Inlet, and after scrubbing the outlet SO₂ concentration can be ≦30 vppm, the scrubbed tail gas temp. can be re-heated up to ≧135℃ by a MS Steam Re-Heater to avoid white plume produced at Stack Exit；meanwhile, the effluent COD ≦1,000 mg/l, PH：6~9 after scrubbing, and the effluent temp. ≦38℃ by using an Effluent Cooler are required to be met.
