ICC - Process Overview Image: //cdn.intratec.us/images/icc/process-overview/375-G.jpg
ICC - Process Overview Text: <h6>Product</h6> <p><b>Dimethyl Ether</b>. Dimethyl Ether (a.k.a. DME), is the simplest aliphatic ether, containing only two carbon atoms. This organic compound has been used in the production of the methylating agent dimethyl sulfate, as an aerosol propellant, coolant and in a number of other applications. More recently, DME has attracted considerable attention as a synthetically produced alternative to diesel, able to produce clean energy in the future.</p> <h6>Raw Materials</h6> <p><b>Carbon Dioxide</b>. Carbon dioxide is a colorless and incombustible gas with chemical formula CO2; a naturally occurring chemical present in the atmosphere. Formed during respiration, this gas is obtained by several ways and at various scales, based on carbon-based fuels combustion, carbohydrates fermentation, limestone thermal decomposition, as byproduct of the industrial production of hydrogen by steam reforming and ammonia synthesis, etc. Carbon dioxide is a versatile chemical with a number of applications, being widely used in the production of carbonated beverages, as an inert gas and as a pressurizing gas. In the chemical industry, it is mainly used in the production of urea, methanol, metal carbonates and bicarbonates.</p> <b>Natural Gas</b>. Natural gas is a naturally occurring mixture of hydrocarbon found in porous subsurface geologic formations. It is composed mainly of methane, but also contains varying amounts of higher hydrocarbons such as ethane, propane, and butane. Additionally, natural gas may also include non-hydrocarbon components considered impurities such as nitrogen, carbon dioxide, and hydrogen sulfide. Natural gas is primarily used as a source of heat energy for residential, commercial, and industrial applications. It may also be used in the production of important chemicals such as ammonia, methanol, and hydrogen. </p>
ICC - Process Schematic Image: //cdn.intratec.us/images/icc/process-schematics/375-G.jpg
ICC - Process Schematic Text: <p>The process under analysis comprises three major sections: (1) Syngas Production; (2) DME Synthesis; and (3) Purification.</p><p>Syngas Production. Natural gas feedstock is treated in zinc oxide beds, for removing sulfur compounds, and in a pre-reformer (fixed-bed-type reactor), that converts higher hydrocarbons contained in the feed gas into a gas rich in methane and hydrogen, in order to protect the catalysts. Then, the treated gas is fed to a dry reformer, in which the methane reacts catalytically with CO2, generating CO and H2 (syngas). The reformer outlet stream is cooled, compressed and then fed to absorption column for the separation of unconverted CO2 by means of a methanol wash.</p><p>DME synthesis. The syngas is then fed to a fixed-bed synthesis reactor, in which it is directly converted to DME. Such direct synthesis of DME is carried out in the presence of a bifunctional zeolite-based catalyst system (Cu-Zn-Al/ZSM-5 catalyst). The reactor outlet gas is mainly comprised of DME, methanol, CO2 and unconverted hydrogen and CO. </p><p>Purification. The effluent from DME synthesis is cooled, and DME and methanol are separated from the gases by condensation. The separated gas is partially recycled to the DME synthesis, with a small purge. The DME-methanol condensate stream is then passed through distillation columns. In the CO2 column, carbon dioxide is removed from the DME and recycled to the dry reforming. In the DME column, DME product is purified from methanol and directed to storage facilities located outside battery limits. Finally, wastewater is separated in the methanol column and the methanol obtained is recycled to the DME synthesis.</p>
ICC - Short Description: The report presents the economics of Dimethyl Ether (DME) production from natural gas and carbon dioxide (CO2). In the process under analysis, natural gas is reformed with CO2 yielding synthesis gas (syngas). Syngas is then fed to a one-step process for DME generation - syngas conversion into methanol and methanol dehydration into DME are carried out in a single reaction step. The economic analysis performed assumes a plant located in the United States.
