Abstract

Unit Utilitas Pabrik Kaltim-3 PT. Pupuk Kalimantan Timur, Bontang merupakan unit yang menunjang pembuatan Pupuk Urea dan Amonia. Dalam unit utilitas terdapat beberapa unit penunjang salah satunya adalah Unit Waste Heat Boiler (WHB). Unit Waste Heat Boiler (WHB) merupakan unit pembangkit steam yang memanfaatkan kalor gas buang keluaran sistem pembangkit listrik Gas Turbine Generator (GTG) untuk mengubah air menjadi superheated steam. Gas buang GTG masih memiliki energi termal cukup besar yang dapat dimanfaatkan kembali untuk menunjang proses produksi. Selain memanfaatkan gas buang keluaran sistem pembangkit listrik GTG, Waste Heat Boiler (WHB) juga mendapatkan kalor tambahan (supplementary firing) yang berasal dari pembakaran natural gas. Untuk mengetahui efisiensi dari sistem gabungan Unit Waste Heat Boiler (WHB) dan unit Gas Turbine Generator (GTG) diperlukan sebuah analisis termal. Efisiensi sistem gabungan ini bergantung pada konsumsi bahan bakar pada sistem pembangkit listrik Gas Turbine Generator (GTG), penambahan pembakaran bahan bakar (supplementary firing), dan gas buang (exhaust gas) keluaran sistem pembangkit listrik Gas Turbine Generator (GTG) yang dimanfaatkan untuk memanaskan air hingga menjadi superheated steam. ======================================================================================================== Utility Unit Kaltim-3 PT. Pupuk Kalimantan Timur, Bontang is a unit that supports production of urea and ammonia. There are several units that support utility unit, one of which is the Unit Waste Heat Boiler (WHB). Waste Heat Boiler (WHB) Unit is a steam generating unit which utilizes exhaust gas from Gas Turbine Generator (GTG) to change water into superheated steam. Exhaust gas of GTG still has a considerable energy can be recovered to support the ongoing production process. In addition to utilizing the waste gas power generation system output GTG, Waste Heat Boiler (WHB) also get additional heat (supplementary firing) from the combustion of natural gas. To determine the efficiency of the combined system Unit Waste Heat Boiler (WHB) and units of Gas Turbine Generator (GTG) required a thermal analysis. The efficiency of the combined system is depend on the fuel consumption in power generation systems Gas Turbine Generator (GTG), the addition of fuel combustion (supplementary firing), and the capacity of the exhaust gas (exhaust gas) output power systems Gas Turbine Generator (GTG) which is used for heat the water up to become superheated steam.
