EVALUASI KINERJA TURBINE CONDENSER E-2302 SEBELUM DAN SESUDAH DILAKSANAKAN TURN AROUND 2016

PT. Kaltim Parna Industri (KPI) is an ammonia plant with a capacity of 1,500 MPTD. The purity of the products produced 99.95% by weight. The process that is used in PT. KPI is Haldor Topsoe Process. The raw material used to produce ammonia is natural gas (as a source of H2) and air (as a source of N2). PT. Kaltim Parna Industri has two main units of production processes and utilities. In the production process of the unit there are several major units, unit desulphurizer, reforming system consists of primary and secondary reformer, CO Converter unit consisting of High and Low Temperature CO Converter (HTS and LTS), CO2 units, unit methanator, and ammonia converter. In the unit utility has main units, there are units of sea water intake, units of desalination, demineralization, daerator, Package Boilers, Water Heat Boiler, sea water cooling towers, waste water treatment system, chlorination, STG and emergency diesel denerator, N2 generator, instrument water, and storage tanks. Turbine Condenser E-2302 has the main function to condense steam low to utilize the latent heat which is then used to drive a steam turbine-pump (TS / P-2301A / B). Overall heat transfer coefficient of turbine condenser E-2302 prior to Turn Around (TA) has an efficiency of 88.964% and afterTurn Around (TA) of 94 928% with heat transfer coefficient calculation technique overalls using calor compared with area and LMTD (Log Mean Temperature Difference).
