Abstract

Negara Indonesia dikenal sebagai negara agraris, dimana banyak masyarakat nya yang bekerja di sector pertanian. Karena itulah, tingkat konsumsi pupuk di Indonesia sangat tinggi karna merupakan komponen penting untuk kualitas tumbuhan. Pupuk urea adalah pupuk yang mengandung unsur Nitrogen sebanyak 46% yang berperan dalam pembentukan dan pertumbuhan bagian-bagian vegetative tanaman seperti pembentukan klorofil, membentuk lemak, protein, dan mempercepat pertumbuhan daun, batang dan akar. Pembangunan pabrik urea direncanakan memiliki kapasitas 600.000 ton/tahun pupuk urea dalam bentuk prill, dimana pabrik akan didirikan di Kawasan Industri Kariangau, Balikpapan. Kawasan ini cukup dekat dengan sumber bahan baku, serta memadai dalam factor transportasi serta utilitas. Berdasarkan analisa neraca massa dan energi, pabrik ini membutuhkan bahan baku sebanyak 2122 ton/tahun NH3 dan 1223 ton/tahun CO2 dengan kebutuhan steam 51.270 kg/jam, cooling water 16.557.227 kg/jam serta listrik sebesar 11.193 KW/tahun. Pabrik ini terdiri dari enam tahap, yaitu sintesa, purifikasi, konsentrasi, pembutiran, recovery, serta condensate treatment. Bahan baku pada awalnya akan masuk sebagai liquid dan direaksikan menjadi urea pada reactor dengan kemurnian sekitar 30%. Kemudian, bahan baku yang belum berhasil bereaksi akan direaksikan Kembali di seksi selanjutnya untuk mendapatkan kemurnian urea hingga 99,7%. Larutan urea akan dipadatkan dalam bentuk prilling pada seksi pembutiran menggunakan alat prilling tower. Berdasarkan perhitungan yang dilakukan, pabrik urea memadai untuk didirikan dengan nilai IRR = 20,2%, NPV = 310,4 Juta Dolar, dan Pay Out Time (POT) selama 3 tahun

Indonesia is known as an agricultural country, where many people work in the agricultural sector. For this reason, the level of fertilizer consumption in Indonesia is very high because it is an important component for plant quality. Urea fertilizer is a fertilizer that contains as much as 46% Nitrogen which plays a role in the formation and growth of vegetative parts of plants such as the formation of chlorophyll, forming fat, protein, and accelerating the growth of leaves, stems and roots. The construction of the urea factory is planned to have a capacity of 600,000 tons/year of urea fertilizer in prill form, where the factory will be built in the Kariangau Industrial Area, Balikpapan. This area is quite close to sources of raw materials, as well as adequate in terms of transportation and utilities. Based on mass and energy balance analysis, this plant requires 2122 tons/year of NH3 and 1223 tons/year of CO2 raw materials with a steam requirement of 51,270 kg/hour, cooling water of 16,557,227 kg/hour and electricity of 11,193 KW/year. This plant consists of six stages, namely synthesis, purification, concentration, granulation, recovery, and condensate treatment. The raw material will initially enter as a liquid and be reacted to become urea in a reactor with a purity of about 30%. Then, the raw materials which have not been successfully reacted will be reacted again in the next section to obtain urea purity up to 99.7%. The urea solution will be compacted in prilling form in the granulation section using a prilling tower. Based on calculations made, the urea plant is sufficient to build with an IRR value of 20.2%, NPV = 310.4 Million Dollars, and a Pay Out Time (POT) of 3 years
