This paper investigates a combined process of dehydrogenation and etherification to produce tertiary amyl methyl ether (TAME) from light naphtha fractionated to extract isopentane. It proposes that by integrating this combined process into an integrated refining-petrochemical enterprise aimed at para-xylene (PX) production, the oversupply of light naphtha can be mitigated, while freeing up more aromatic feedstocks for PX production. Using PIMS software to simulate the overall process flow of the whole plant, the results indicate that the combined process can reduce gasoline output by 744,000 TPY while indirectly increasing aromatic production by 216,000 TPY. Economic calculations show that if the surplus gasoline is sold at a discount exceeding 422 yuan per ton, the internal rate of return (IRR) of the combined units of isopentane dehydrogenation and isopentene etherification will exceed 10%. This process technology is mature and low-risk, offering a new idea for optimizing refinery production processes.
