Abstract

Chemical phenomena involving three phases (solid, liquid, and gas) are often found in the industry.
Carbonate (CaCO3) is widely used in industries as a powder-making material in the cosmetic
industry, a pigment in the paint industry, and filler in the paper and rubber industry. This research
aim to study the ordering process carbonate deposits (CaCO3) from the absorption process of CO2
gas with Ca(OH)2 suspension. The absorption reaction of CO2 gas with Ca(OH)2 suspension was
carried out in a stirred slurry tank reactor. Initially, the reactor containing water was heated to a
certain temperature, then Ca(OH)2 was added to the reactor. Furthermore, CO2 gas with a certain
flow rate and temperature (according to the reactor temperature) is flown with the help of a gas
distributor. Samples were taken every 1 min until the concentration of Ca(OH)2 could not be detected
(completely reacted). The variables in this study were: stirrer rotation speed (5.66711.067 rps), CO2
gas flow rate (34.0127–60.5503 c/s), and temperature (30–50°C). The mass transfer coefficient and
the reaction rate coefficient were determined by minimizing Sum of Squares of Errors (SSE). This
experimental process follows a dynamic regime. A dimensionless number relationship for the gasliquid mass transfer for the value range is Re1 = 18928.76-38217.20, Sh = 0.07928 Reg
0.4383 Rel
0.4399
Sc0.6415 with an error of 5.19%. The dimensionless number relationship for solid-liquid mass transfer
is Sh = 0.0001179 Reg
0.4674 Rel
0.5403 Sc1.444 with an error of 7.31%. The relationship between the
reaction rate constant and the temperature in the 30-50 °C range can be approximated by the
Arrhenius equation, namely kr = 1771000 e-2321.4/T cm3
/mgmol/s with an error of 3.63%.
