Carbon Dioxide (CO2) Absorption Process Using Sodium Hydroxide (NaOH)

Carbon dioxide capture from atmospheric air using sodium hydroxide spray.

In contrast to conventional carbon capture systems for power plants and other large point sources, the system described in this paper captures CO2 directly from ambient air. This has the advantages that emissions from diffuse sources and past emissions may be captured. The objective of this research is to determine the feasibility of a NaOH spray-based contactor for use in an air capture system...

Modelling of a Gas-Absorption Packed Column for Carbon Dioxide-Sodium Hydroxide System

This paper present a research work on the modeling of a gas absorption packed column with the aim formulating a mathematical model and simulation of the model using a computer software to obtain the rate of absorption and the amount of absorbed carbon dioxide CO2 into dilute sodium hydroxide NaOH. Arm field gas absorption column titration techniques were used for the analysis. The total concent...

An Experimental Investigation of Reactive Absorption of Carbon Dioxide into an Aqueous NH3/H2O/NaOH Solution

In this research, the reactive absorption of carbon dioxide in an aqueous solution of NH3, H2O, and NaOH has experimentally been investigated. The experiments were carried out in an absorption pilot plant in different operational conditions. The composition and temperature of both gas and liquid phases were obtained during the column height. The concentration of molecular ...

Ventilation Efficiency and Carbon Dioxide (CO2) Concentration

In animals metabolic processes, involve complex organic molecules being broken down to simpler molecules, such as carbon dioxide and water. Carbon dioxide waste is removed from the body through respiration. Carbon dioxide content in fresh air is approximately 400 parts per million. In this study, we investigate the relationship between ventilation efficiency and carbon dioxide (CO2) concentrati...
