The recovered waste oil may be reused or at least sold for road oil, and the treated waste-water may be reused to satisfy plant process, cooling, or other non-potable water demands. Carried to the ultimate end, such reuse may virtually eliminate plant waste-water discharges, thereby negating the involvement with waste-water regulatory agencies.
In August 2015, Magaldi has been selected by Stag AG as the supplier of two air cooled slag removal systems for the Zürich Hagenholz (CH) Waste Incineration Plant. The patented Magaldi Ecobelt® WA conveyors (to be installed in 2016) are retrofitting the present traditional wet slag removal system, handling and cooling it in a complete dry mode.

Another byproduct issue at the Polk plant deals with slag disposal. Although the slag is classified as non-hazardous, local regulations require disposal in a different class of landfill. Polk must use a Class I landfill that is double-lined with leachate extraction/control versus a much less expensive and more available Class III landfill.
1–8%. The slag basicity from BOF slag is in the range of 3.5, which is higher than the basicity of EAF slags with a basicity of about 2.0. The SMP slags often have an even higher basicity of around 46. Steel slag is a secondary resource of raw material in metallurgical plant. It can be directly taken back to
The plant is one of the largest Chinese waste-to-energy plants and it is specifically designed for Chinese waste. This includes the waste characteristics with high moisture and low calorific value. The Likeng II plant has 3 lines of 750 tonnes waste capacity per day each, based on B&W Vølund engineering design and key components.
Plasma gasification is an extreme thermal process using plasma which converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide.A plasma torch powered by an electric arc is used to ionize gas and catalyze organic matter into syngas, with slag remaining as a byproduct. It is used commercially as a form of waste .
The slag falls at high temperature from the furnace grates to a bunker. From this pit, it is collected by a gantry crane and unloaded onto a vibrating screen. At an adjacent plant that is capable of handling 120 tons of slag per hour, the slag is converted to materials .
Current Experience with Gasification Slag Utilization In addition to the successful assessment of Wabash slag to produce lightweight aggregate, the Polk plant has successfully processed slag for use in cement production. In order to meet the required slag specification, the size of the fines handling system was doubled, and additional slag ...

Sep 29, 2014· The main waste materials in the BOF steel making are converter slag, scrap, waste refractories, converter muck, and gas cleaning plant (GCP) sludge. Except GCP sludge all other waste materials are usually generated in mixed condition which means that during generation one waste material gets contaminated with other waste material.
Mar 01, 2007· Two types of blast furnace slag such air-cooled slag and granulated slag are being generated from the steel plants. In India around 40% of this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately 2.90 with its bulk density varying in the range of 1200–1300 kg/m 3 .
