Es ist vielfach belegt, dass den Kriterien der Objektivität und Überprüfbarkeit klinische Beobachtungen allein nicht standhalten. Vielmehr bedürfen sie der Absicherung durch Daten, die über quantitative und

Ying Zhang,Hui Fan,Weimin Huang,Yan Chend from metallurgical plants based on copper pyrites, zinc pyrites, iron pyrites, etc. Moreover, many consumers of sulfuric acid have started using waste sulfuric acid available at a much lower price instead of the fresh acid. The spread of sulfuric acid manufacturing plants has made it uneconomical

https://doi.org/10.1007/0-387-28173-8Earlier designs of sulfuric acid plants preferred minimizing initial capital cost and hence heat recovery equipment was not common. For example, these designs had atmospheric cooling ducts, air cooled heat exchangers, or air injection facilities instead of waste heat recovery boilers and economisers.

Wojciech Burakowski,Andrzej BebenSulfuric acid is called the king of chemicals. The first step to produce a useful product is sulfonation. Since the direct use of sulfuric acid is not feasible in all applications, the following auxiliary agents do play an important role. These are:

https://doi.org/10.1007/0-387-28173-8As the manufacture of sulfuric acid has increased over the years, plant designers, operators, and maintenance engineers have developed and improved the technology for its manufacture, leading to more efficient plants. These developments are briefly presented as improvements/innovations in process, catalyst, plant equipment, etc.
