Two carbon capture and desulfurization projects at the Nanjing Chemical Research Institute passed the evaluation. Author/Source: Sinochem News Network. Date: 2021-12-02. Clicks: 12. On November 13, the projects \"Expanded tests on amino acid salt-based solvents for carbon dioxide capture\" and \"Development of new technologies using high-performance organic amines to remove SO₂ from off-gases\", carried out by Sinopec Nanjing Chemical Research Institute Co., Ltd., passed the project evaluation organized by Sinopec’s Science and Technology Department. “The “Scale-up Test of Amino Acid Salt Carbon Dioxide Capture Solvent” project optimized the developed formula and process using a pilot-scale device with a capacity of 5–10 Nm3/h, resulting in a solvent loss rate 90% lower than that of MEA. At the same time, quantum chemical calculations were used to determine the underlying factors for the high energy consumption in amino acid salt regeneration. “The solvent formula developed for removing SO₂ in flue gases, as part of the project \"Development of a new high-performance organic amine-based technique for SO₂ removal\", boasts an oxidation resistance of over 70% and a corrosion resistance of 98%. It is capable of purifying feed gas with an SO₂ concentration of up to 17,143 mg/Nm3 to levels below 50 mg/Nm3; at the same time, this solution absorbs almost no carbon dioxide from the feed gas.

It is capable of purifying feed gas with an SO₂ concentration of up to 17,143 mg/Nm3 to levels below 50 mg/Nm3; at the same time, this solution absorbs almost no carbon dioxide from the feed gas. The company has been in industrial operation for 3 years now; the SO2 level can be reduced to 30 mg/m3, with a steam consumption of 70 kg per ton of rich liquid.
