1. Proj. Name：SRU Tail Gas Emission Revamping Facilities Turnkey Project

2. Client：Tao-yuan Refinery of CPC Corp., Taiwan

3. Proj. Period：Oct. 2015～Nov. 2016

4. Proj. Description：

This project is to comply with environmental regulation requirements of air pollution control and focus on abnormal operation during startup/shutdown and de-sulfur process of SRU #2 & #3 of Refinery Section II, Tao-yuan Refinery.  After installing a tail gas treatment facilities, which will be able to reduce SO₂ emission concentration and minimize odor smell in air, it can be expected to create a better environmental air quality.  By those revamping facilities, the high concentration of 1% SO₂ content in tail gas will be scrubbed by caustic soda solution and the emission of SO₂ concentration shall be decreased to ≦50ppmv, and also the Chemical Oxygen Demand (COD) of Waste Water effluent from the facilities shall be limited less than 1,000vppm.
