ANALISIS SISTEM PENDINGIN PADA SEALTUBE HEAT EXCHANGER 881X PADA UNIT REFINERY DENGAN CLEAN COOLING WATER DI PT TUNAS BARU LAMPUNG, TBK CABANG PALEMBANG

PT Tunas Baru Lampung Tbk, Banyuasin is a company with the main
production in the form of Cooking Oil located in Banyuasin KM 14. The process of
making cooking oil requires many tools that have roles and functions, one of which
is the Clean Cooling Tower and Sealtube Heat Exchanger, where the Sealtube Heat
The 881X exchanger works to cool the hot fluid, namely Refined Bleached
Deodorized Plam Oil (RBDPO) from the Deodorization Section process by utilizing
cold fluid in the form of Cooling Water. Cooling Tower is widely used to increase
productivity and efficiency in the production process at PT Tunas Baru Lampung,
Tbk Palembang Branch. Cooling tower performance Assess approach and
operating range to design value and Identify areas of energy wastage. In order for
the distillation process to run smoothly, the Cooling Tower must work optimally to
reduce the temperature of the hot RBDPO so that the RBDPO process can continue
to the next process. The purpose of this study, among others, is to determine the
working efficiency of the Clean Cooling Tower tool on the Sealtube Heat Exchanger
in the Refinery unit by calculating Evaporation Loss, Drift Loss, Blowdown, Total
Make Up Water on the Sealtube Heat Exchanger and to determine the cooling
capacity and work efficiency of Cooling Water. on the Sealtube Heat Exchanger at
PT Tunas Baru Lampung, Tbk Palembang Branch. The data collection used is field
study, observation, log sheet and literature study. The results of this study have a
value that is still efficient enough to produce air lost due to blowdown, evaporation
and evaporation loss.
