EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Technological solutions, to utilize process gases from the iron and steel industry, to allow other production facilities , e.g. chemical industry, to use such energy sources, is becoming more and more attractive. One possible way, to convert the available energy from carbon and hydrogen-rich off-gases, such as coke oven gas, blast furnace top gas, direct reduction gas and also converter BOF...

Industry follows only the agriculture sector as main water consumer, as water is fundamental for all process steps from the cooling to the washing stages, from the product formulation to the mass separation. In particular, steelworks use significant amount of water in cooling and washing systems. However, higher freshwater cost and environmental regulation pressurise industry toward an...

During production of ethylene, propylene and butadiene at SABIC olefin plants, coke is deposited on furnace tubes. Deposited coke layer increases with time which reduces furnace efficiency. Hence, removal of coke through de-coking process-stage is frequently required followed by landfilling of collected waste coke. Moreover, HADEED imports carboneous additives or recarburizers to be added...

The generation of renewable electrical energy will not fulfil the electrical energy consumption at any time. Therefore there will be “surplus” electrical energy in the electrical energy system that must be used to gain grid stability. The PtL technology consumes that “surplus” electrical energy and incorporates simultaneously the substantial usage of CO2 as feedstock for its conversion to...

Zinc enters the steel production through the feeding of galvanized steel scrap into the electric arc furnace (EAF). Based on the process conditions, the zinc oxide gets reduced, evaporates as metallic zinc, reoxidizes to zinc oxide in the offgas and gets collected in the filter house. Beside zinc, which represents the main component, elements like lead, iron, cadmium, sodium, potassium,...
