Abstrak

Asam Nitrat merupakan salah satu produk industri kimia yang digunakan sebagai bahan baku industri kimia, bahan baku peledak, nitrating agent, oxidizing agent, pelarut, katalis dan hydrolizing agent. Asam Nitrat dapat diproduksi melalui beberapa proses yaitu 1) Proses Oksidasi Ammonia, 2) Proses Retort, dan 3) Proses Electrical Arc. Dalam Pra-Rancangan Pabrik Asam Nitrat ini dipilih proses Electrical Arc yang ditinjau dari segi ekonomi dan termodinamika lebih menguntungkan dibandingkan dengan proses lainnya. Kapasitas produksi pabrik direncanakan 55.000 ton/tahun dengan 330 hari kerja dalam 1 tahun. Lokasi pabrik direncanakan didirikan di Kawasan Industri Gresik, Kab. Gresik, Jawa Timur. Tenaga kerja yang dibutuhkan sebanyak 168 orang dengan bentuk badan usaha Perseroan Terbatas (PT) yang dipimpin oleh seorang Direktur Utama yang dibantu oleh Direktur Produksi, Direktur Pemasaran dan Keuangan, serta Direktur SDM dan Umum dengan struktur organisasi line and staff. Penyediaan kebutuhan utilitas pabrik berupa sistem pengolahan dan penyediaan air, cooling water, sistem penyediaan udara instrumen, dan sistem pembangkit tenaga listrik. Dari analisis ekonomi diperoleh: Fixed Capital Investment (FCI) = Rp 442.854.394.558 Working Capital Investment (WCI) = Rp 78.150.775.510 Total Capital Investment (TCI) = Rp 521.005.170.068 Break Even Point (BEP) = 30,51% Shut Down Point (SDP) = 12,25% Pay Out Time before taxes (POT)b = 2,19 tahun Pay Out Time after taxes (POT)a = 2,59 tahun Return on Investment before taxes (ROI)b = 30,32% Return on Investment after taxes (ROI)a = 24,26% Discounted cash flow (DCF) = 24,73% Mempertimbangkan rangkuman di atas, sudah selayaknya pendirian pabrik Asam Nitrat ini dikaji lebih lanjut, karena merupakan pabrik yang menguntungkan dan mempunyai prospek yang baik. abstract Nitric acid is one of the chemical industry products used as raw material for chemical industry, explosive raw material, nitrating agent, oxidizing agent, solvent, catalyst and hydrolizing agent. Nitric acid can be produced through several processes: 1) Ammonia Oxidation Process, 2) Retort Process, and 3) Electrical Arc Process. In the Pre-Design of Nitric Acid Plant is selected Electrical Arc process in terms of economics and thermodynamics is more profitable compared with other processes. Plant’s production capacity is planned 55,000 tons/year with 330 working days in a year. The location of the plant is planned to be established in Industrial Estate Gresik, Kab. Gresik, East Java. Manpower needed as many as 168 people with a business entity form Limited Liability Company (PT) which is headed by a President Director who is assisted by Production Director, Marketing and Finance Director, and Director of Human Resources and General with line and staff organization structure. Provision of utility plant needs a treatment systems and water supply, cooling water, instrument air supply systems, and power generation systems. From the economic analysis is obtained: Fixed Capital Investment (FCI) = Rp 442.854.394.558 Working Capital Investment (WCI) = Rp 78.150.775.510 Total Capital Investment (TCI) = Rp 521.005.170.068 Break Even Point (BEP) = 30,51% Shut Down Point (SDP) = 12,25% Pay Out Time before taxes (POT)b = 2,19 tahun Pay Out Time after taxes (POT)a = 2,59 tahun Return on Investment before taxes (ROI)b = 30,32% Return on Investment after taxes (ROI)a = 24,26% Discounted cash flow (DCF) = 24,73% Consider the summary above, it is proper establishment of the Nitric Acid plant is studied further, because the plant is profitable and has good prospects.
