Desulfurization and Deashing of Hazro Coal by Selective Oil Agglomeration in Various Water Mediums

Abstract

The aim of this study was to study the effects of various water mediums on desulfurization and deashing of Hazro coal by the agglomeration method. For this purpose, three groups of agglomeration experiments were made. The effects of some parameters that markedly influence the effectiveness of selective oil agglomeration, such as solid concentration, bridging liquid concentration, and pH, on the agglomeration were investigated in the first group of experiments. The effects of different salts (NaCl, MgCl 2 , and FeCl 3 ) on the agglomeration were investigated in the second group of experiments. The effects of lake water and sea water on the agglomeration were investigated in the third group of experiments. The influences of the Mediterranean Sea water and Aegean Sea water on the removal of ash and total sulfur were found to be important.

Selective Oil Agglomeration of Lignite

“…However, the combustible yields obtained in the agglomeration of Hazro sub-bituminous coal containing 24.77% ash and 6.90% total sulfur (air-dried base) were found to be high when the Mediterranean Sea water was used in agglomeration medium. 24 The results are consistent with those reported by Fan et al 3.3.1. Effect of NaCl.…”

“…The total sulfur content of the lignite was reduced from 2.72 to 1.13%. Similiar results were reported by Temel and Ayhan 24 for Hazro sub-bituminous coal.…”
