Production of Portland clinker is inherently associated with CO2 emissions originating from limestone decomposition, the irreplaceable large-scale source calcium oxide needed. Besides carbon capture and storage, mineralization only lever left to reduce these process emissions. a reversal reaction production—CO2 bound into stable carbonates in an exothermic process. It can be applied several env...
Cement manufacturing is one of the most energy intensive processes and is accountable for substantial pollutant emissions. Increasing energy costs compel stakeholders and researchers to search for alternative options to improve energy performance and reduce CO2 emissions. Alternative fuels offer a realistic solution towards the reduction of the usage of fossil fuels and the mitigation of pollut...
The dusty challenge Obtaining reliable level measurement has traditionally been a severe challenge because cement production is such a dusty process. During homogenization, for example, silos are continuously filled and emptied, and the component materials are constantly aerated to ensure good mixing. This creates a tremendous amount of dust that makes it difficult to obtain reliable readings w...
New molten salt chemistry allows solar thermal energy to drive calcium oxide production without any carbon dioxide emission. This is accomplished in a one pot synthesis, and at lower projected cost than the existing cement industry process, which after power production, is the largest contributor to anthropogenic greenhouse gas emissions.
ارزیابی مواجهه شغلی کارکنان یک کارخانه تولید سیمان با گرد و غبار قابل استنشاق سیمان و سیلیس کریستالی
Introduction: Exposure to respirable fraction of cement dust and its crystalline silica content is the most important occupational risk factor in cement industries requiring more evaluation and monitoring. This study aimed to assess exposure to crystalline silica and cement dust among workers of a cement industry in Saveh city, Iran. . Material and Method: In this cross-sectional study, 62 s...
