Vaporized very pure methanol is catalytically dehydrated to yield Dimethyl ether in a fix-bed reactor by using a catalyst. The reactor effluent is charged to the Dimethyl ether distillation section. The remaining methanol/water mixture is charged to the methanol distillation tower, the methanol is recycled in the methanol stream. Water is the only by-product of the production process.
Akzonobel’s process technologists are continuously improving the safety and efficiency of the DME process plant, resulting in our capacity expansion in 2013, ready to support the growing demand of DME.
