AI Technical Summary

Benefits of technology

This patented technology describes an apparatus called a thermal recycling system (TRS). It includes multiple rows of heat exchangers placed next to each other along their length within the engine's smoke stack chamber. These heat exchanges take place between different gases during combustion processes inside the furnace or boiler. By utilising this arrangement, these systems reduce fuel usage while also recovering excessive amounts of nitrogen oxide emissions. Additionally, they have been developed specifically designed to efficiently remove harmful substances such as hydrocarbons and particulate matter from flue gases produced when burning fossil fuels like coal. Overall, TRS helps optimize power generation by minimizing wasted resources caused by NOx emission.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency at which recovered nmolone (NP) from exhaust gases emitted during manufacturing processes for Lithium ion secondary cells or batteries that use these gasses. Current methods are either too complicated or result in poorly captured NMs being released into the atmosphere due to high volatility.
