Sodium Silicate

Sodium silicates are mostly used for the production of detergents. Moreover, they are needed in big volumes as basic product for the manufacture of silicic acid as additives for rubbers and plastics and cracking catalysts for the petro-chemical industry. They are also used for the synthesis of zeoliths, kieselgels and brines, for glues, as binding agent for aqueous painting colours, for ore flotat...read more

Titanium Dioxide

Two different types of processes are used for the production of titanium dioxide in Germany : the sulfate process and the chloride process. In Germany, titanium dioxide is produced at four plants, three of them apply the sulfate process, one of them uses the sulfate as well as the chloride process.    read more

Sodium Perborate

The manufacture of sodium perborate takes place as tetrahydrate at first, which is converted in a second process to monohydrate by means of dehydration. Both compounds, the tetrahydrate as well as the monohydrate can be used for the production of detergents. The monohydrate is also used for the manufacture of dishwashing detergents.read more

NPK-Fertilizer

Multi-nutrient fertilizers have increasingly gained importance in the last decades mainly for economic reasons, but also due to technical and physiological aspects. According to the type of manufacture, they are divided into mixed fertilizers and complex fertilizers. The manufacture of mixed fertilizers is generally effected by simply mixing dry single fertilizers, so that there are not caused any...read more

Soda

The annual world production of sodium carbonate (soda) amounted to approximately 31,5 million tons in 1993. The main share is synthetic soda. Nowadays it is only manufactured by means of the Solvay technology, which – as it uses NH3 as auxiliary material – is also called „ammonia soda process“. Approximately 35 % of the world production is natural soda, mainly manufactured in the USA.  read more

Large Volume Gaseous and Liquid Inorganic Chemicals

Synthesis gases are mixtures from hydrogen and carbon monoxide. Raw materials are solid, liquid or gaseous fuels, which react under additivation of oxygen and / or steam at higher temperatures. Often the production of synthesis gas is a very economic recycling process of residues, which can provide the basis for basic chemical products, e.g. methanol. So heavy vacuum distillation residuals from re...read more
