Sistema autóctone de remoção de CO2: purificando atmosferas confinadas

Abstract

The accumulation of contaminants, such as carbon dioxide, in confined atmospheres without natural renewal is one of the operating limitations of submarines, where a purification system is necessary to treat its confined atmosphere. Removing the carbon dioxide generated by the crew is a critical technological challenge, as harmful effects to the crew are already observed even at low concentrations. In this condition of low CO2 partial pressures, it is difficult to remove this contaminant. The present work presented an innovative technology to keep the confined atmosphere purified, using contacting membrane and gas permeation modules. A national contactor module was manufactured and a computacional model was developed for sizing the equipment.
