Pra Rancangan Pabrik Pembuatan Metil Salisilat dengan Proses Esterifikasi Metanol dan Asam Salisilat dengan Kapasitas 4.000 Ton/Tahun dan Tugas Khusus Rancangan Keteknikan Reaktor Alir Tangki Berpengaduk (RATB)

Abstract

This methyl salicylate production plant from salicylic acid and methanol with esterification process has a production capacity of 4.000 tons/year and operates for 330 days a year. The main process in the pre-design of this factory consists of three stages, namely the raw material preparation stage, the esterification reaction process, the neutralization reaction process, and the methyl salicylate purification process. The reaction is an esterification reaction of salicylic acid and methanol with a sulfuric acid catalyst which takes place in a stirred tank flow reactor at a temperature of 68oC. The amount of acetaldehyde required to achieve annual production capacity is 1.125,562 kg/hour. The planned factory location is in Brongsong Village, Kendal Regency, Central Java Province. with a total plant area of 14.634 m2. Water needs in this factory are supplied from the Waridin River as much as 1.907,182 kg/hour. The required workforce is 114 people with the form of a Limited Company (Ltd) with a line and staff organizational structure. For the establishment and operation of the factory it requires capital investment of IDR 421.476.202.954 and production costst of IDR 104.478.602.951. Based on the feasiblity analysis, this plant has a BEP 30,11%, ROI 17,86% POT for 5,6 years, RON 29,78%, and IRR of 17,21%. Based on the economic analysis, it can be concluded that plant is feasible to established
