Abstract

Meningkatnya perkembangan industri kimia di indonesia
menyebabkan kebutuhan akan bahan baku dan bahan oenunjang nya juga
mengalami peningkatan. Asam sulfat merupakan salah satu bahan kimia
yang tergolong bahan baku yang selalu meningkat setiap tahunnya.
Kapasitas pabrik asam sulfat yang akan didirikan pada tahun 2024 ini
adalah 850.000 ton/tahun. Lokasi yang dipilih untuk pendirian pabrik asam
sulfat dari bahan baku belerang ini yaitu pada Kelurahan Kanaan,
Kabupaten Bontang Provinsi Kalimantan Timur. . Proses pembuatan asam
sulfat dengan proses double contact double absorber (DCDA) yang terdiri
dari lima unit tahapan. Tahap pertama yaitu Sulfur Handling, tahap kedua
yaitu SO2 Generation, tahap ketiga yaitu SO2 Conversion, tahap keempat
yaitu Drying & SO3 Absorption, tahap terakhir yaitu H2SO4 Storage &
Distribution. Pabrik ini direncanakan beroperasi secara kontinyu selama
330 hari/tahun dengan basis 24 jam/hari. Bahan baksu sulfur yang
dibutuhkan sebesar 2.779,98 kg/jam. Pada pabrik asam sulfat ini, kami
menlaukan efisiensi kinerja Heat Exchanger. Dari hasil perhitungan
menggunakan metode Sizing Known didapatkan heat exchanger dengan tipe
Cross Flow both unmixed dengan hasil efisiensi sebesar 99,64%. Hasil ini
dapat mempengaruhi luas area, capital cost, total cost, jumlah shells dan
penambahan satu alat heat exchanger terhadap kondisi design berupa heat
exchanger dan proses fluida di dalamnya. Berdasarkan analisa kelayakan
ekonomi , pabrik asam sulfat dengan kapasitas 850.000 ton/tahun telah layak
untuk didirikan dengan NPV, IRR, POT dan BEP yang diperoleh sebesar Rp.
449.099.665.735,74; 19%; 2,3 tahun dan 18,08%.
================================================================================================
The increasing development of the chemical industry in
Indonesia causes the need for raw materials and supporting materials to
also increase. Sulfuric acid is one of the chemicals classified as raw
materials that always increases every year. The capacity of the sulfuric
acid plant to be established in 2024 is 850,000 tons/year. The location
chosen for the establishment of the sulfuric acid plant from sulfur raw
material is Kanaan Village, Bontang Regency, East Kalimantan
Province. . The process of making sulfuric acid using a double contact
double absorber (DCDA) process which consists of five units of steps. The
first stage is Sulfur Handling, the second stage is SO2 Generation, the
third stage is SO2 Conversion, the fourth stage is Drying & SO3
Absorption, the last stage is H2SO4 Storage & Distribution. This plant is
planned to operate continuously for 330 days/year on a 24 hour/day basis.
The required sulfur feedstock is 2,779.98 kg/hour. In this sulfuric acid
plant, we carry out the efficiency of Heat Exchanger performance. From
the results of calculations using the Sizing Known method, a heat
exchanger with the Cross Flow type both unmixed was obtained with an
efficiency of 99.64%. These results can affect the area, capital cost, total
cost, number of shells and the addition of one heat exchanger to the design
conditions in the form of a heat exchanger and the fluid process in it.
Based on the economic feasibility analysis, a sulfuric acid plant with a
capacity of 850,000 tons/year is feasible to be established with NPV, IRR,
POT and BEP obtained amounting to Rp. 449.099.665.735,74; 19%; 2.3
years and 18.08%.
