Topsoe’s DME technology converts methanol into DME (dimethyl ether). The technology is characterised by a high degree of feedstock flexibility, operating on crude methanol as well as refined methanol for the DME synthesis. Topsoe’s DME process applies a simple and robust adiabatic reactor and is characterised by efficient heat integration between the process and the utilities sections ensuring low energy consumption.

Topsoe's hydrogen technology and catalysts ensure optimised processes with low energy consumption. Topsoe's hydrogen technology is designed for feedstock variation and operates on feedstocks from natural gas to heavy naphtha. Due to the processes' high energy efficiency NOx and CO2 emissions are low. Topsoe's research programme has contributed extensively to improvements in process technology and development of specialised equipment for critical processing steps. Relevant equipment includes tubular reformers, convection reformers, bayonet reformers, and waste heat boilers.

Topsoe’s methanol technology converts feedstock such as natural gas and synthesis gas from coal gasification into methanol. The methanol plant consists of three main process sections: synthesis gas production, methanol synthesis and methanol distillation, of which the synthesis gas production is the most cost intensive.  As Topsoe offers a variety of technologies for synthesis gas production it is possible to select the optimal technology for specific plant conditions, primarily determined by the capacity of the plant and the cost of feedstock, thus lowering investment and operating costs.

The SCR (Selective Catalytic Reduction) process is the most efficient process for removing nitrogen oxides (NOx) from gases. In the process NOx reacts with ammonia over a catalyst to form elementary nitrogen and water vapour without creating any secondary pollutants. Topsoe’s SCR DeNOx process and catalysts are suitable for treating off-gases from a long range of different industries and applications including fossil-fuel and biomass fired utility boilers, gas turbines, oil refining and chemical plants, stationary diesel engines and waste incinerators.

The SNOX™ process removes sulphur and nitrogen oxides from flue gases, recovers the sulphur oxides as concentrated sulphuric acid and reduces the nitrogen oxides to free nitrogen. The process is based on catalytic reactions and does not consume water, absorbents or chemicals, except for ammonia for the reduction of nitrogen oxides. The SNOX™ process can be applied for treatment of flue gases from combustion of primarily high-sulphur fuels in power stations, refineries and other industrial boilers and for treatment of other waste gases containing sulphur compounds and nitrogen oxides.

Topsoe's integrated gasoline synthesis process - TIGAS - is ideal for the processing of synthesis gas to gasoline. In an improved version of the methanol-to-gasoline process, TIGAS converts synthesis gas into gasoline in a single-loop process, thus eliminating the requirement for upstream methanol production and intermediate storage.

Topsoe's Recycle Methanation Process - TREMP™ - constitutes an important step in the production of substitute natural gas (SNG) from carbonaceous feedstocks such as coal, petcoke and biomass. Topsoe's TREMP™ technology ensures en efficient heat recovery and thereby improves plant efficiency. The TREMP™ technology produces a natural gas compatible with pipeline specifications, ensuring easy distribution of the product.

Topsoe’s Wet gas Sulphuric Acid technology (WSA) recovers sulphur from off-gases in the form of commercial-grade concentrated sulphuric acid and regenerates spent sulphuric acid. The WSA process is a wet gas catalytic process where the concentrated sulphuric acid is produced by condensation from a wet process gas. As the process gas is not dried prior to treatment in a WSA plant, generation of waste water and loss of sulphur is avoided.
