Chemical Treatment of the Water Used in Blast Furnaces Gases Cleaning Cycle, in The Egyptian Iron - Steel Company
Mona Abdel Fattah Abdel Aziz;
Abstract
Cooling towers in blast furnaces gas cleaning unit in Egyptian Iron and Steel Company (EISCO) are used for the removal of heat from the gas washing water.
The basic problem of water chemistry for all the cooling systems is to be protected from corrosion, scales and fouling from slit or microbiological growth.
The aim of the present work is to study the blast furnace gas cleaning and cooling water properties which causes blocking and corrosion of cooling tower pipes at the EISCO, and to investigate the most appropriate and economic methods for the treatment, this is in order to be suitable for recycling, where the average discharge flow rate in the water cycle of the
blast furnaces gas cleaning water is 2500 m 3/h.
The scope of the experimental work covers the study of the blast furnace gas cleaning water properties, which include suspended solids from gas cleaning, water hardness in settling unit and zinc content in scales .
Sampling selection in the EISCO was established inorder to cover water samples, wet and dry sludge samples from settling tanks and scale samples from cooling towers and pipes. These samples reflect the different pollutants that proposed to be treated.
