ArcelorMittal South Africa (AMSA) is the largest steel producer in Africa, producing 4.8 million tonnes of steel per year through an integrated process. Through working with the Industrial Energy Efficiency Project, AMSA implemented an energy management system and optimized various energy systems, such as compressed air, pumps, fans, and steam. These optimization projects are estimated to save AMSA approximately R105 million per year in electricity and natural gas costs. Pump system optimization assessments alone have identified potential savings of over R36 million at reduced payback periods.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

2. ArcelorMittal South Africa (AMSA) is the largest steel producer in Africa.
AMSA produces 4.8 million tonnes per year of saleable steel.
The plant’s steel products are manufactured in an integrated process.
Raw materials such as iron ore, coke and dolomite are charged to blast
furnaces where they are converted to liquid iron.
The liquid iron is refined in basic oxygen furnaces and electric arc
furnaces to produce liquid steel.
The liquid steel is cast into slabs, which are hot rolled into heavy plate in
a plate mill, or into coils in a strip mill.
The coils are either sold as hot rolled sheets in coil or processed further
into cold rolled and coated products, such as hot dip galvanised, electro-
galvanised and pre-painted sheet, and tinplate.

10. • Recommendations (without large capital) :
• Sump level increase to 100%.
• Automatic level control for top-up.
• Redesign suction pipe in order to reduce pressure loss
o Use bigger size pipe;
o Regularly clean strainers; and
o Remove elbow on inlet.
• Regularly clean heat exchangers.
• Adjust flow based on temperature.
• Confirm ΔT requirements of the ‘BF closed loop’ system and
calculate the required flow rate of the ‘open’ loop system.
• Compare flow requirements with cooling degree days.
• Operate a single pump year round.
