Toward Net-Zero Emission Fertilizers Industry: Greenhouse Gas Emission Analyses and Decarbonization Solutions

Energy & Fuels, Год журнала: 2022, Номер 36(8), С. 4198 - 4223

Опубликована: Апрель 4, 2022

The production of fertilizers has been evolving steadily in the last 300 years. It involves a high number commodities and reagents that share large portion costs emissions greenhouse gases (GHGs), particularly carbon dioxide (CO2). Phosphorus, nitrogen, potassium components represent more than 200 million tonnes annually. Given most fertilizer process is dependent on fossil fuels as fuel feedstock, amount CO2 generated at least 3 per tonne fertilizer. introduction, future, less intensive technological lower energy-consuming separation catalytic technologies industry potential to reduce drastically. In this review, we thoroughly analyze GHG over time explore pathways achieve viable sustainable decarbonization solutions. also aim explore, whenever information available, factors (sources) ranges different value chains plants. As result, an overview literature from synthetic (N, P, K) industries will be given. More emphasis stem extraction raw materials final products (energy source, efficiency, type) transportation intermediates within sites plants (vehicle type, efficiency). A perspective analysis possible recommendations for future net-zero capture made.

Potential uses of phosphogypsum: A review

Journal of Environmental Science and Health Part A, Год журнала: 2022, Номер 57(9), С. 746 - 763

Опубликована: Июль 29, 2022

AbstractAbstractPhosphogypsum (PG) is a by-product of the phosphate fertilizer industry that produced during phosphoric acid production process. Annual global PG ranges between 100 to 300 Mt, with only 15% utilized while rest usually placed on large dumps potential serious human and environmental impacts. The aim this study give an overview evaluate existing uses extend from soil stabilization cement chemical for agricultural geotechnical, impacts, applications. More specifically, can be used as substitute in industry, building materials road construction, improvement, raw material some chemicals, backfilling rehabilitation abandoned mines quarries, recovery gypsum extraction rare earth elements signifies importance cyclic economy. paper offers extensive PG, discusses their adequacy, reveals widely under certain conditions, rather than disposed waste stockpiles.Keywords: Uses phosphogypsumsoil stabilizationagriculturerehabilitation quarries Data availability statementThe data presented review are openly available according respective reference number appears text tables.FundingThe author(s) reported there no funding associated work featured article.

The chemical behavior of the different impurities present in Phosphogypsum: a review

Phosphorus, sulfur, and silicon and the related elements, Год журнала: 2023, Номер 199(2), С. 129 - 148

Опубликована: Ноя. 17, 2023

Phosphogypsum (PG) is an acidic by-product that created during the production of phosphoric acid using sulfuric route. The management PG poses a significant environmental challenge worldwide due to its large quantity and chemical composition. While primarily consists calcium sulfate dihydrate, it also contains various impurities such as phosphorus, fluoride, heavy metals, radionuclides. These toxic impurities, when present in high concentrations, can have adverse effects on environment human health. In this review, we provide detailed examination behavior most abundant found PG. Furthermore, discuss factors influence presence different types Understanding overall these crucial for selecting appropriate methods identifying suitable avenues valorization.
