THE EFFECT OF MIXING DEMINERALIZED WATER AND CONDENSATE ON BOILER OPERATIONAL EFFICIENCY AT PT LOTTE CHEMICAL TITAN NUSANTARA
Keywords:
Boiler feed water, condensate, cost efficiency, demineralization, water qualityAbstract
This study determines the optimal mixing ratio of demineralized water and condensate for boiler feedwater at PT Lotte Chemical Titan Nusantara by balancing water quality and cost efficiency. Parameters evaluated were pH, conductivity, phosphate, silica, and total iron for five mixing ratios: 100% demin, 75:25, 50:50, 25:75, and 100% condensate. Increasing condensate fraction moderately increased pH, conductivity, phosphate, and total iron while remaining within operational limits. The 25% demineralized water : 75% condensate ratio provided safe water quality and reduced operating costs by up to 67.5%, making it the optimal composition.
