Abstract

Methanol market in Indonesia is projected to grow with Compound Annual Growth Rate of 3.2% by 2034. Utilizing natural gas as a feedstock and employing carbon capture and storage technology using activated metildietanolamin with piperazine (MDEA-PZ), the process is designed to produce methanol with a low carbon footprint. The process design and simulation were carried out using Aspen HYSYS, focusing on mass and energy balances across pre-treatment, syngas formation, methanol synthesis, purification and carbon capture stages. The pilot-scale plant with a capacity of 100,000 tons per year located in the Special Economic Zone (KEK) Arun, Aceh, demonstrating promising results with an Internal Rate of Return (IRR) of 11.73%, a Net Present Value (NPV) of USD 166.63 and levelized cost of methanol (LCOM) of 611.61 $/ton MeOH. Compared to other low emission chemical plant, this plant offers promising economic feasibility.

Abstract

This study designs a benzene production plant from natural gas in the Arun Gas Field, Aceh, Indonesia, with a focus on sustainability and economics. The plant could support Indonesia's government efforts in achieving the Enhanced Nationally Determined Contribution and carbon credit objectives. Using DWSim simulation, the processes modeled consists of natural gas purification, dehydroaromatization reaction, and benzene separation. The results demonstrate high efficiency in producing benzene with a purity of 99.5%-wt. Economic analysis indicates that the investment in this plant is financially viable, with an internal rate of return of 12.2%, a payback period of 7.6 years, and an 8.93% return on investment.  By combining sustainability and economic profitability, this research provides a foundation for the implementation of an environmentally friendly and sustainable benzene production plant in the Arun Gas Field.
