Title: [abstract] A SOLID AMINE CO2 REMOVAL SYSTEM IN A SELECTED ENVIRONMENT.

Abstract: Maintaining ambient CO2 concentration at a desired level is vital for human activity in a sealed environment, such as submersible vehicles. Current CO2 removal systems, i.e., soda lime or lithium hydroxide chemical absorbent units and regenerative liquid amine system, are limited in their use due to their volume and energy consumption. We have developed a new CO2 removal system utilizing solid amine which is reclaimed and reused in the system. The solid amine was developed for this system. The system basically consists of multiple towers in parallel containing the solid amine, and a steam generator to reclaim CO2 bound solid amine. One of the towers is always reclaiming CO2 bound solid amine, and the remaining towers work as CO2 removers. A prototype model of the system with four towers was evaluated for CO2 removal performance in various conditions with ambient air containing 1% CO2. Results showed that the system can continuously remove about 50% of CO2 in ambient air, ranging from 40 to 60% in a cyclic mode, when air flow to the system was maintained at 0.13 normal cubic meter/min/kg of solid amine, and that energy requirement for CO2 removal and reclaim was 5 W/h/normal liter CO2. It was confirmed that the ability of the system to remove ambient CO2 is sufficient to use in a sealed environment. The advantage of the system is that the size and number of the solid amine towers can be changed according to the requirement of ambient CO2 levels and the size of the sealed environment.
