An analysis of current methanol to olefin development technology: DMTO and SMTO

The global demand for ethylene and propylene is about 200 million tons per year, which requires a very efficient and large number of separation systems. It is necessary to study the chemical packaging system, which is effective and emits fewer pollutants. Based on the existing literature and data, this paper includes two main advanced technologies from the Dalian Institute of Chemical Physics, the Chinese Academy of Sciences DMTO and SINOPEC Shanghai Petrochemical Research Institute SMTO. Specific analysis and optimization of energy loss and product loss in each process are carried out. The result shows that optimization of reaction conditions and other ways to improve the conversion rate and product selectivity is currently the main direction, as is the development of more energy-efficient new high-efficiency separation technology to achieve energy savings. At present, there is still ample room for innovation in the research of catalysts and the corresponding supporting reactor types, in addition to meeting quality requirements and further optimizing the process for technological innovation.
