Modeling of CO₂ absorption with K₂COз diethanolamine-piperazine compound using packed column method

In recent years, interest in the development of carbon dioxide (CO2) removal technology has increased due to the impact on global warming and climate change, which is mainly due to the large amount of CO2 emissions generated from various natural activities and human activities that are leached directly into the atmosphere. Common methods often used in the chemical industry to separate CO2 gas from process gases include absorption using chemical solvents by using a pakced column method. This study aims to obtain data on CO2 loading and CO2 removal in K2CO3-H2O solution with DEA-PZ promotor, and to determine the effect of concentration and temperature variables on CO2 loading and CO2 removal using modelling. This research was conducted with a variable temperature of 40°C-60°C, a concentration of 30% K2CO3, 1-3% DEA and 0.75% PZ using a packed column in atmospheric pressure. The results of the data validation obtained have an average % error of 7-12% based on previous research. The parameters obtained are the optimal temperature at 55oC and CO2 loading and CO2 removal increases along with the increase in the concentration of DEA-PZ promoter The effect of the PZ promoter as an additional solution has an important role in increasing the effectiveness of absorption.
