Dimethylamine (Production from Alcohols, ELCD)
The data set covers all relevant process steps / technologies over the supply chain of the represented cradle to gate inventory with a good overall data quality. The inventory is mainly based on secondary data. This dataset is based on secondary data from internationally adopted production processes.
Dimethylamine belongs to the group of lower alkylamines. For those, the common production process is the reaction of the appropriate alcohol with ammonia over suitable catalyst. In case of dimethylamine the reactants would be methanol and ammonia. In this reaction, the product is always a mixture of primary, secondary, and tertiary amines because the primary amine formed initially can react further with one or two molecules of alcohol. While the initial conversion of the alcohol to the primary amine is close to thermo neutral, the formation of secondary and tertiary amines is exothermic and thus thermodynamically favoured. In 2000 the commercial use of the alcohol route was prevalent.
The background system is addressed as follows:
Electricity, Thermal energy: The electricity (and thermal energy as by-product) used is modelled according to the individual country-specific situation. The country-specific modelling is achieved on multiple levels. Firstly the individual power plants in service are modelled according to the current national grid. This includes net losses and imported electricity. Second, the national emission and efficiency standards of the power plants are modelled. Third, the country-specific fuel supply (share of resources used, by import and / or domestic supply) including the country-specific properties (e.g. element and energy contents) are accounted for. Fourth, the import, transport, mining and exploration processes for the energy carrier supply chain are modelled according to the specific situation of each power-producing country. The different mining and exploration techniques (emissions and efficiencies) in the different exploration countries are accounted for according to current engineering knowledge and information.
Steam: The steam supply is modelled according to the individual country-specific situation with regard to the technology efficiencies and energy carriers used. Efficiencies range from 84% to 94% in relation to the representative energy carrier (gas, oil, coal). Coal, crude oil and natural gas used for the generation of steam are modelled according to the specific import situation (see electricity).
Energy carriers: Coal, crude oil, natural gas and uranium are modelled according to the specific import situation (see electricity).
Refinery products: Diesel, gasoline, technical gases, fuel oils, basic oils and residues such as bitumen are modelled via a country-specific, refinery parameterized model. The refinery model represents the current national standard in refinery techniques (e.g. emission level, internal energy consumption,...) as well as the individual country-specific product output spectrum, which can be quite different from country to country. Hence the refinery products used show the individual country-specific use of resources. The supply of crude oil is modelled, again, according to the country-specific crude oil situation with the respective properties of the resources.
