Abstract

Asam salisilat memiliki karakterisitik antara lain berbentuk serbuk kristal, warna putih dan meleleh pada suhu 157-159 oC. Pabrik ini mengunakan proses karboksilasi Kolbe-Schmitt dan mempunyai kapasitas sebesar 91200 kg asam salisilat/hari. Lokasi pendirian pabrik di kawasan industri Cilegon dipilih berdasarkan ketersediaan bahan baku, air dan kemudahan transportasi. Dalam proses pembuatan asam salisilat ini meliputi tiga tahap, yaitu pembentukkan natrium phenolate, natrium salisilat dan asam salisilat. Pada tahap pembentukkan natrium phenolate, phenol direaksikan dengan larutan NaOH 55% kondisi operasi 90C 1 atm. Pada tahap pembentukkan natrium salisilat, natrium phenolate direaksikan dengan gas CO2 pada kondisi operasi 175C 4 atm. Pada tahap pembentukkan asam salisilat,natrium salisilat direaksikan dengan H2SO4 98% pada kondisi operasi 60C 1 atm. Pabrik ini direncanakan beroperasi selama 330 hari /tahun dan 24 jam /hari. Total bahan baku utama yang dibutuhkan sebesar 17478,13 kg/hari dengan bahan baku pendukung yaitu karbon aktif. Kebutuhan utilitasnya adalah air sanitasi, air boiler, air pendingin, dan air proses yaitu masing-masing sebesar 84 m3/hari, 3152,8 m3/hari, 509,22 m3/hari, dan 928,32 m3/hari ======================================================================================================================== The characteristic of salicylic acid are crystal powder, white, and melt in temperature of 157-159 oC. This salicylic acid plant use Kolbe- Schmitt carboxylation process with a capacity of 91200 kg salicylic acid/hour. This plant located in Cilegon, the location is chosen for its raw material and water avaliability, also the ease of transportation. Salicylic acid production process consists of 3 stages, which are formation of sodium phenolate, sodium salisilate and salicylic acid. In the formation of sodium phenolate, phenol is reacted with NaOH 55% process at 90C 1 atm. In the formation of sodium salisilate, the sodium phenolate is reacted with CO2 with a process at 175C 4 atm. In the formation of salicylic acid, the sodium salisilate is reacted with H2SO4 98% with a process at 60C 1 atm. This plant is projected to operate batch for 24 hours/day and 330 days/year. This plant required 17478,13 kg/day of raw material and activated carbon as the supporting materials. The water utilities required for this plant are sanitation water, boiler water, cooling water, and process water respectively by 84 m3/day, 3152,8 m3/day, 509,22 m3/day, and 928,32 m3/day
