Abstract: The methanol production process through the reforming unit is a crucial step in converting natural gas into synthesis gas, which is used as the primary feedstock in synthesizing high-quality methanol (grade AA). Periodic evaluation of the reforming unit performance is essential to ensure process optimization and the synthesis of gas quality. This study uses Aspen HYSYS software simulations to analyze the effect of operating conditions and natural gas feedstock characteristics on reforming unit performance. The analysis was carried out by comparing the composition of natural gas at two different periods, identifying the key parameters that affect methane conversion, and evaluating the effect of temperature and pressure on synthesis gas quality. The results showed increased operating temperature and pressure contributed to increased methane conversion and H₂/CO ratio. High methane content in the feed plays a vital role in the efficiency of the reforming reaction, although the presence of other compounds can inhibit the process. The results showed that on May 31, with better operating conditions, syngas with a composition of 67.64% were produced compared to 67.28% on July 24. However, the increased feed flow rate on May 31 led to higher energy consumption. The conclusion of this study confirms the importance of optimizing operating parameters such as temperature, pressure, and feed composition to improve methanol production efficiency and yield. In addition, the balance between methane and C₂⁺ hydrocarbons in natural gas largely determines the efficiency of methanol synthesis.
