With the increasing demand for efficient chemical process technologies, dimethyl ether (DME) production has attracted growing attention due to its wide range of industrial applications. Reactor design plays an important role in achieving stable operation, effective heat management, and reliable production performance.

Nanjing Dunxian Chemical Technology Co., Ltd.has developed DME Reactor solutions based on advanced reactor design concepts and chemical process experience. The reactor is designed with an internally cooled structure, consisting of a shell and internal heat exchange tube bundle to provide suitable reaction conditions for methanol dehydration.

During the DME production process, methanol gas enters the reactor from the upper section and passes through the internal heat exchange structure before reaching the catalyst bed. After the dehydration reaction, the generated DME gas exits the reactor and continues to subsequent processing stages.

Dunxian DME Reactor technology adopts a methanol-to-DME one-step process, integrating methanol vaporization, methanol dehydration, DME distillation, and DME storage. The process design also applies multi-stage heat recovery to improve energy utilization and support stable industrial operation.

According to the supplied product information, the Dunxian DME Reactor achieves a single-pass methanol conversion rate of ≥86%, with DME purity reaching ≥99.9 wt%. The reactor design maintains an appropriate operating temperature to reduce side reactions and support consistent product quality.

With continuous investment in reactor technology development,
Nanjing Dunxian Chemical Technology Co., Ltd.provides professional reactor solutions, proprietary equipment supply, process support, and technical services for chemical industry customers worldwide.
