Abstract

Industri asam fosfat merupakan salah satu industri di Indonesia yang memiliki prospek yang cukup besar di masa mendatang, mengingat asam fosfat merupakan salah satu bahan baku dalam pembuatan pupuk, dan saat ini perkembangan industri pupuk semakin meningkat namun tidak di dukung dengan jumlah produksi asam fosfat di Indonesia, sehingga perlu direncanakan pendirian pabrik asam fosfat dengan bahan baku batuan fosfat dan asam sulfat dengan proses basah. Berdasarkan bahan baku, kemudahan transportasi, sumber air dan lahan, rencana lokasi pendirian pabrik adalah di Gresik, Jawa Timur. Pembuatan asam fosfat dengan proses basah melalui 5 tahap, tahap petama yaitu tahap screening yang bertujuan untuk memisahkan batuan fosfat yang undersize dan oversize dengan ukuran 200 mesh, tahap kedua yaitu tahap rock grinding yang bertujuan untuk menghancurkan batuan sampai dengan ukuran 200 mesh, tahap ketiga yaitu tahap reaction yang bertujuan untuk mereaksikan batuan fosfat, asam sulfat dan air untuk menjadi asam fosfat dan gypsum, tahap keempat yaitu tahap filtration yang bertujuan untuk memisahkan asam fosfat dengan gypsum dan tahap kelima yaitu evaporationyang bertujuan untuk memekatkan asam fosfat hingga kemurnian 75% H3PO4 Pabrik asam fosfat bekerja secara kontinyu dan beroperasi selama 330 hari/tahun dengan kapasitas produksi 170.000 ton/tahun. Bahan baku berupa batuan fosfat yaitu sebesar33599,18 kg/jam dan bahan baku asam sulfat yaitu sebesar 41434,25 kg/jam. Kebutuhan utilitasberupa air sanitasi, air umpan boiler, air pendingin dan air proses masing-masing 3,8 ; 12,07 ; 183,23 ; 42,2 m3/jam. Limbah yang dihasilkan dari industri asam fosfat ini yaitu gypsum yang akan diolah untuk bahan baku pada industri semen

The phosphoric acid industry is one of the industries in Indonesia that has a considerable prospect in the future, considering that phosphoric acid is one of the raw materials in making fertilizers, and currently the development of the fertilizer industry is increasing but is not supported by the amount of phosphoric acid production in Indonesia, so that it is necessary to plan the establishment of a phosphoric acid plant with phosphate rock and sulfuric acid raw materials by wet process. Based on raw materials, ease of transportation, water sources and land, the planned location of the factory establishment is in Gresik, East Java.Making phosphoric acid with a wet process through 5 stages, the first stage is the screening stage which aims to separate the phosphate rock that is undersize and oversized with a size of 200 mesh, the second stage is rock grinding stage which aims to destroy rocks up to 200 mesh in size, the third stage is reaction stage which aims to react phosphate rock, sulfuric acid and water to become phosphoric acid and gypsum, the fourth stage is the filtration stage which aims to separate phosphoric acid with gypsum and the fifth stage is evaporation which aims to concentrate phosphoric acid to 75% purity $\text{H}_3\text{PO}_4$.The phosphoric acid plant works continuously and operates for 330 days/year with a production capacity of 170.000 tons/year. The raw material in the form of phosphate rock is equal to 33.599,18 kg/hour and the raw material for sulfuric acid is 41.434,25 kg/hour. Utility needs in the form of water sanitation, boiler feed water, cooling water and process water respectively 3,8; 12,07; 183,23; 42,2 $\text{m}^3\text{/hour}$. The waste produced from the phosphoric acid industry is gypsum which will be processed for raw materials in the cement industry.
