Effects of reactor stages on energy and economic performance of methanol to aromatics process

摘要:Increasing the stages of methanol aromatization reactor can significantly improve the aromatics yield. However, it remains inconclusive whether the increase in reactor stages is benefit to the whole methanol to aromatics (MTA) process. Based on four cases with different reactor stages including a single-stage, a two-stage and two three-stage reactors, this work conducted full-flow simulation for MTA process. In this paper, energy analysis and techno-economic analysis were performed for the four cases, aiming to explore the effect of reactor stages on the whole MTA process. The results showed that the aromatics yield in the three-stage reactor cases were as 180.74% and 163.72% as that in the single-stage and two-stage reactor cases, respectively. In terms of energy consumption, compared to the single-stage reactor-based case, the two-stage and three-stage reactor cases led to lower value. The economic analysis indicated that increasing the reactor stages resulted in higher total capital investment and total annual production cost, but much faster investment return could be gotten, showing increasing profitability.
