Optimalisasi Penyerapan Gas Clo2 Di Absorber Chlorine Dioxide Plant#6

---

Chlorine dioxide (ClO2) is a chemical used as a bleaching agent in the pulp bleaching process. At the integrated ClO2 plant PT. RAPP, ClO2 solution with a concentration of 9.9-10 ± 0.2 g/L is obtained through the process of absorbing ClO2 gas using Chilled Water in the absorber. This research aims to determine the effect of temperature, chilled water flow, water dilution flow on the absorption process that occurs in absorber plant #6. This research uses primary and secondary data collection methods, where primary data was obtained from laboratory analysis results and secondary data was obtained from company data in the Chemical Plant department with variations in Chilled water temperatures of 6oC, 7oC, 8oC, Flow chilled water by varying ClO2 Solution 10,3-10,14 g/L, 9,98-10,5 g/L, 9,98-9,91 g/L and water dilution flow 70 kg/day – 120 kg/day. From the results of the analysis carried out, If the concentration is high, the amount of flow chilled water used to absorb ClO2 gas tends to be small so that unabsorbed ClO2 gas increases, the higher the chilled water temperature will produce ClO2 solution with a lower concentration. Whereas the lower the chilled water temperature will produce a ClO2 solution with a high concentration and too much flow dilution water, the more ClO2 gas will be carried away. While the flow dilution of water is small or small, the ClO2 gas released will be less but there will be a risk of decomposition of ClO2 gas. In this study, the optimum conditions for the absorption process at absorber CP#6 with chilled water temperature 6ºC, chilled water flow ratio at chilled water flow ratio 79.48, 80.55, 80.51 concentration 9.84-9.91 g/L and water dilution flow ratio at water dilution flow ratio 47.11 kg/hour.

Key words: Absorber, absorption, Chlorine dioxide, Optimal.
