PRARANCANGAN PABRIK METHANESULFONIC ACID (MSA) DARI METHANE DAN SULFUR TRIOXIDE DENGAN KAPASITAS 29000 TON/TAHUN

Abstract

Methanesulfonic Acid (CH3SO3H) is produced from Methane (CH4) and Sulfur Trioxide (SO3). By using the waste gas produced from the Embalut PLTU, the production of Methanesulfonic Acid can be produced from the Flue Gas by using SO2 compounds which will be oxidized to form SO3. So that SO3 reacts with CH4 to produce the desired product, namely MSA. Methanesulfonic Acid produced in this process produces 98%. With this purity the product compound can have many benefits in various industrial fields. This plant is designed to be able to produce a high-value product using emission gas discharged by the industry, so that it becomes a solution to environmental problems and also becomes a factory profit. The capacity of flue gas used for processing is about 4000 tons / day and produces Methanesulfonic Acid product compounds of 29,000 tons / year with continuous operation for 330 days per year. This plant was built in the city of Samarinda, East Kalimantan Province based on the location that has been considered. From the results of the design, an economic analysis was carried out to determine the feasibility of the plant with the following results. For total capital investment in the results worth Rp3,659,061,817,499.79, Total Production Cost (Rp1,711,853,410,115.56), Total Sales per Year (Rp3,004,668,544,065.98), Profit after tax (Rp1. 905,470,312,093,700), (ROI) before tax (353.3187%), Simple Payback Period (8.7737 years), Discounted Payback Period (12.05 years), Break Even Point (BEP) (24.9031%), Shutdown Point (SDP) (11.8556%). Based on the analysis values obtained, the plant is very feasible to be applied in Indonesia.
