CCUS moving towards scale: Alcohol amine corrosion and high-pressure CO₂ transportation drive process pump upgrades
2026-09-05 12:19:05 378 江苏海珐In 2026, global CC continues its transition from demonstration to large-scale deployment. According to the latest IEA, large-scale carbon capture, transport, and storage projects continue to expand, with more than 30 projects reaching final investment decisions in the two years and related investment exceeding USD 5 billion in 5. The current engineering challenge has shifted from "whether capture is feasible" to "whether-term stable operation can achieved." Under the presence of CO₂, SO₂, NOₓ, and oxygen, amine systems such as MEA and MDEA/PZ undergo solvent degradation, formation of heat-stable salts (HSS), and carbon steel corrosion. Research in 2026 further indicates that corrosion differences among various blended amine systems are significant, SO₂ impurities can alter the protective mechanism of corrosion films. Meanwhile, CCUS is strengthening engineering routes such as-phase CO₂, supercritical CO₂, CO₂ liquefaction, ship-based CCS, solvent reclaiming, and-time corrosion monitoring. In 2026, the Mizushima industrial area in Japan has advanced the integrated design of CO₂ capture, liquefaction temporary storage, and shipping. Jiangsu Haifa Machinery Manufacturing Co., Ltd (www.jslgpump.com) provides API OH2 process pumps, BB3/BB5 high-pressure multistage pumps, VS series pumps, and API 685 magnetic drive pumps for CCUS, offering NPSH verification, corrosion-resistant material matching, API 682 sealing, and high-pressure structural design tailored to amine circulation, lean/rich solution transfer, CO₂ pressurization, and corrosive media conditions, thereby reducing risks of cavitation, leakage, and unplanned shutdowns, and providing fluid transfer solutions for the localization of million-tonne-scale CCUS facilities.
