Pra Rancangan Pabrik Pembuatan Hidrogen dan Karbondioksida dari Metanol dan Air dengan Proses Termal Metode Methanol Steam Reformer dengan Kapasitas Bahan Baku 10 Ton/Jam

Abstract

This preliminary plant design aims to produce hydrogen and carbon dioxide through the Methanol Steam Reforming process with a feed capacity of 10 tons per hour. This process utilizes methanol and water as the primary feedstocks, which undergo catalytic reforming at high temperatures to generate hydrogen and carbon dioxide as the main products. This technology is chosen for its efficiency in producing high- purity hydrogen and its potential to support decarbonization and energy transition efforts in Indonesia. The reactor operates at an inlet temperature of 300°C with a metal oxide-based catalyst. To enhance product separation efficiency, a Pressure Swing Adsorption (PSA) system is implemented for hydrogen purification. Additionally, the carbon dioxide produced can be utilized as an industrial feedstock or stored as part of greenhouse gas emission mitigation efforts. The plant is planned to be established in East Kalimantan on a 11,700 m² plot of land. A preliminary economic analysis indicates that this plant presents a viable investment opportunity with competitive profit projections. The plant has a Break-Even Point (BEP) of 43%, a Return on Investment (ROI) of 10.27%, and a Payback Period (POT) of 9.7 years. Additionally, the Rate of Return on Net Investment (RON) is 20.74%, and the Internal Rate of Return (IRR) reaches 55.17%. By considering both technical and environmental aspects, this design is expected to contribute to the advancement of clean energy technologies and support the nation’s carbon neutrality targets in the future.
