Dimethyl Ether Production from Synthesis Gas (Indirect Method)

This report presents the economics of Dimethyl Ether (DME) production from synthesis gas through a two-step process. In this plant, synthesis gas is converted into methanol in an isothermal reactor combined in series with a gas-cooled reactor. Methanol obtained from previous step is fed to a catalytic dehydration reaction over an aluminum-based catalyst to yield DME.

The report provides a comprehensive study of Dimethyl Ether production and related Dimethyl Ether production cost, covering three key aspects: a complete description of the Dimethyl Ether production process examined; an in-depth analysis of the related Dimethyl Ether plant capital cost (Capex); and an evaluation of the respective Dimethyl Ether plant operating costs (Opex).

The Dimethyl Ether production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Dimethyl Ether plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Dimethyl Ether plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.
