| Summary: | In the pulp and paper industry, various methods are used to mitigate CO2 emissions, one
of which is CO2 fixation through its conversion into PCC (Precipitated Calcium
Carbonate). One process involves reacting CO2 with Ca(OH)2. This study aims to
determine the optimal method for CO2 emission mitigation by utilizing CO2 from the flue
gas of a biomass co-firing power plant to produce PCC, focusing on variables such as
CO2 injection flow rate and carbonation reaction time. The study is conducted by setting
a specific scope, defining fixed variables aside from the main research objectives, which
include operational conditions, microbubbler size, concentration of Ca(OH)2, and initial
reaction pH.
From the research, it was found that optimal CO2 binding occurs at a low flow rate and
when the reaction time reaches the equilibrium pH of CaCO3. In this study, the optimal
flow rate was found to be 0.1 L/min, with a reaction time of 3 minutes to reach a reaction
pH of 8.2, where no further conversion occurred, and the maximum conversion achieved
was 69.57%. The equilibrium reaction pH for CaCO3 occurred at around pH 8, as no more
CO3
2- ions were formed at lower pH levels. The pH change data in this experiment had
an R-value of 0.99, indicating that the pH change over time was very stable. |
