    • CVS - EAF Design Main Objective q Dry Pump technology for Vacuum System q Integrated solution for Process and Plant Automation (level 1 + 2 Automation) q Innovative Process Control: AI@SOLIS and AI@GAS q Advanced Process Simulation and Optimization q Substantial Energy Saving Solution q Environmental Safe Solution
    • CVS - VD/VOD Dry Mechanical Pump versus Steam Ejectors • Energy and Cost Saving • Higher Hydrogen Elimination and Better Performances on working pressure • Clean and Environmental Friendly Technology • No cleaning required • Full computer controll • Easier Maintenance • Fast turn on / turn off service
    • CVS - VD/VOD Energy and Cost Saving Steam Ejector Spent Energy a typical VD 30 min. Degassing process: Average steam consume for a 800kg/h Steam Ejector: 16 t/h of steam 16t/h x0.5h x 0.85Gcal/t = 6.4 GCal = 7.42 MWh (thermal) Electrical equivalent of thermal energy for power turbines 40% Electrical equivalent of thermal energy consumed by Steam Ejector is therefore: 7.42 MWh x 0.40 = 2.97 MWh (electric) Energy for water pumping (800m3/h): 300 kWh Total Steam Ejector Energy Consume 3.3 MWh Mechanical Pump System consumed power: 450kW x 0.5 h = 225KWh Ratio of consumed power: 3.3MWh/0.225MWh=14.6 times 15 times less energy consume
    • CVS - VD/VOD Higher Nitrogen and Hydrogen Elimination qSievert Law: [ H eq ] = K p H 2 where pH2 is partial pressure of H2 above liquid steel and K is a constant • In case of a steam ejector pH2 is around 66% of total pressure at 1 mbar this means 0.66 mbar; therefore to perform degassing of the steel we need to go under this pressure • In case of dry pumps pH2 is around 0.5% of total pressure therefore the degassing process is more efficient and most important can be done at higher pressure • For a dry pumping system 10 mbar is a good degassing pressure
    • CVS - VD/VOD Clean and Environmental Friendly • No water contamination • Dust concentration in exhaust gas < 5mg/m3 • Global Steel Industry Requirement of Reduced Green House Emission is fully achieved by using Dry Pumping Technology instead of Steam Ejectors Typical view of a Steam Ejector Pipe • Saving Energy Effect on Reduced Carbon Footprint
