Pra-Rancangan Pabrik Pembuatan Metil Merkaptan dari Syngas dan Hidrogen Sulfida dengan Kapasitas Produksi 39.000 Ton/Tahun

Abstract

Methyl Mercaptan is a substance that has many benefits, including: as a raw material for amino acids, namely methanio, which is a complement to animal feed, as a raw material for making polymers, pesticides, dimethyl sulfoxide, namely as a solvent and the main function of methyl mercaptan is as an odorant in propane and natural gas. In the pre-design of this methyl mercaptan manufacturing plant, the targeted production capacity is 39,000 tons/year with a factory process duration of 330 working days in one year. After studying the selection and production process scenarios for making methyl mercaptan, the process stages in making methyl mercaptan can be detailed, including: 1. Raw material preparation process 2. Reaction process 3. Methyl mercaptan purification process The design of the main process equipment determined in the pre-design of the methyl manufacturing plant, namely: 1. Reactor Fixed Bed Multitubular a) Reactor Temperature : 350℃ b) Reactor Pressure : 10 atm 2. Absorbers a) Absorber Temperature : 70℃ b) Absorber Pressure : 10 atm 3. Knock Out Drum 1 a) Knock out Drum Temperature : 70℃ b) Knock out Drum Pressure : 5 atm 4. Knock out Drum 2 a) Knock out Drum Temperature : 30℃ b) Knock out Drum Pressure : 1 atm This methyl mercaptan manufacturing factory is planned to be established in the Jati Barang area, Indramayu Regency, West Java with the required land area of 17,280 m. The business entity form of this company is planned to be a Limited Liability Company (PT) and the organizational form is a line and staff organization with a required workforce of 280 people. The results of the analysis of the economic aspects of this factory design are as follows: • Total Investment Capital : Rp 207,491,074,536.34 • Total Production Costs : Rp 1,551,376,318,176.32 • Sales Proceeds : Rp 1,754,999,136,000 • Net Profit : Rp 375,623,678,397.25 • Profit Margin (PM) : 30.57 % • Break Even Point (BEP) : 48.94 % • Return on Investment (ROI) : 19.64 % • Pay Out Time (POT) : 5.09 years • Return on Network (RON) : 32.73 % • Internal Rate of Return (IRR) : 25.15 % From the results of the economic aspect analysis, it can be concluded that this Methyl Mercaptan manufacturing factory is feasible to be established.
