The Role of the Merseburg Process in Industrial Decarbonisation and Waste Evaluation

Abstract

Due to greenhouse gas emissions in industrial production, global warming and the resulting climate change pose significant threats to a liveable world. The emission of carbon dioxide, which is released as a result of industrial activities, is the most important component that triggers the global warming process. The use of waste material, which is the result of industrial activity, as raw material within the framework of circular economy is of vital importance in terms of the use of sustainable resources. The problem of phosphogypsum, which is released during the production of phosphoric acid, can be eliminated by the Merseburg process. With such waste minimisation, the destruction caused by emission gases such as carbon dioxide in the atmosphere will also be prevented. In this evaluation study, the use of carbon dioxide gas as a raw material is discussed, while reducing the emission values of industries such as cement and thermal power plants that cause large amounts of carbon dioxide emissions from phosphogypsum waste. Although an ammonium sulphate production is foreseen with the evaluation of carbon dioxide and phosphogypsum waste with the Merseburg process, the effect of the impurity content of the waste material used on the recommended ammonium sulphate concentration will be an important research topic. Various protocols are being worked on worldwide in order to minimise the emissions on international scale. The use of the Merseburg process for this and similar processes will provide significant advantages to the manufacturer in reaching the targeted emission amount.
