Experimental Studies on CO2 Capture in a Spray Scrubber Using NaOH Solution

Abstract

Experimental studies on carbon dioxide capture in a spray scrubber are carried out. Fine spray of sodium hydroxide (NaOH) solution is used as CO2 absorbent. Effects of different operating and design parameters, including concentration of NaOH solution, liquid flow rate, total gas flow rate, initial temperature and concentration of carbon dioxide on CO2 removal efficiency are investigated.
