Abstract
The CO2 waste gas from the gas industry contributes to global warming hence it needs to be reduced or further processed. One of the pathways to utilize CO2 produced from the gas industry is used as a raw material for manufacturing chemicals. This study aims to evaluate techno-economic of CO2 hydrogenation to blue methanol. CO2 sources originated from gas fields located in Central Sulawesi and Central Java and hydrogen from PV electrolysis. The process system was simulated using Aspen HYSYS V.12. The technical analysis was performed using CO2 mass consumption, CO2 conversion, and PV area requirement. The economic analysis was performed using a levelized cost of process. The result shows that CO2 mass consumption for gas fields in Central Sulawesi and Central Java were 1.45 and 1.42 ton-CO2/ton-MeOH, respectively. The CO2 conversion was 94.8% and 96.0% for Central Sulawesi and Central Java, respectively. To produce 1-ton of methanol required PV area of 38,146 m2 in Central Sulawesi and 34,965 m2 in Central Java with methanol production cost in Central Sulawesi and Central Java were 1,960.87 and 1,196.21 $/ton-MeOH, respectively.
