To improve the energy efficiency of an industrial process thermochemical storage (TCES) can be used to store excess or typically wasted thermal for utilisation later. Magnesium carbonate (MgCO3) has a turning temperature 396 °C, theoretical potential 1387 J/g and is low cost (~GBP 400/1000 kg). Research studies that assess MgCO3 use as medium TCES material are lacking, and, given its potential,...

The application of calcite rich common clays has marked impact on the formation alkali-activated binders. Experiments have shown that carbonate decomposition can be well controlled via calcination procedure, whereby majority and subsequent CO 2 release occurs above temperature 750 ?°C. decarbonation mostly separated from dehydroxylation layered silicates. Depending composition raw clay material...

this paper discusses the performance evaluation and availability analysis of ammonia synthesis unit of a fertilizer plant. the fertilizer plant is a complex and repairable engineering system comprises of various units viz. shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis etc. one of the most important functionaries...

Graphite deposits may form alternatively by metamorphism of sedimentary rocks and from fluids. Both types occur in supracrustal successions within the Lewisian Complex Northwest Scotland, similarly Palaeoproterozoic across North Atlantic region Canada, Greenland Scandinavia. Carbon isotope compositions show that graphite Scotland had a mixed origin organic matter (schists) decarbonation limesto...
