ANALISIS TEMPERATUR LINGKUNGAN TERHADAP KINERJA COOLING TOWER DI PT. INDOCEMENT TUNGGAL PRAKARSA TBK. P-12 TARJUN KALIMANTAN - SELATAN

Abstract

Abstract Cooling work system at PT. Indocement Tunggal Prakarsa Tbk Tarjun Plant-12 uses a cooling tower marley fan 3 type mechanical draft, counterflow flow 10.221 m3 / h which functions to cool the output water from the condenser through a nozzle to spray it by spraying some water into the air and discharging it into the atmosphere, so water falls into the water basin through a drift eliminator. Environmental temperature affects the cooling tower performance. The cooler the environment the better the cooling tower performance. The effect of environmental temperature and performance on cooling tower is the discussion in this study. The results of calculations in the study show that the environmental temperature affects the cooling tower performance where in the morning until late afternoon at certain temperatures or weather the cooling tower performance experiences a significant increase and decrease. While the average efficiency, the range and approach from 2016 to 2019 has decreased efficiency by 8.44%, decreasing the range by 1.24 ° C and decreasing the approach by 0.82 ° C.
