Benefits of technology

This new type of chemical can reduce its effectiveness when combined with other substances due to their ability to absorb gases from air or water vapor that may be harmful for some people's health if released into our environment during manufacturing processes such as thermal processing steps like heating up materials at high temperatures.

Problems solved by technology

This patented describes different methods or techniques that aim at removing carbon dioxide (CO2) produced during combustion processes. These include traditional wet scrubbing with water followed by dry cleaners such as activated charcoal powder, molecular sieves, ion exchange resins, metal plates/oxides, zeolite materials, and other technologies like catalyst systems. However, these existing solutions have drawbacks including high costs associated with their maintenance due to degraded components over time, potential environmental concerns related to disposable resources needed after treatment has been completed, and poor selectivity towards specific compounds found within exhaust streams.

Abstract

The invention relates to a carbon dioxide separation technique, which is particular applied to an ion additive for carbon dioxide absorbent of organic amines, wherein, the ionic additive contains 0.01%-5% of Rb[UO2SeO4(OH).H2O] and 0.01%-5% Cu2(CO3)OH2. Compared with organic amines without the ion additive, the oxidation speed of the organic amines with the ionic additive can be reduced by around 50% and the electrochemical corrosion can be decreased by 40%.
