How can one remove chlorine/organochlorines from coal (coke precisely). The intention is to recover coke for its reuse without the Chlorine or OCPs.
Removing chlorine or Organochlorines from coal or coke employs several methods including to wash the coal or coke with water or a suitable solvent. This can achieve the removAl of some soluble chlorine compounds and organochlorines. The effectiveness of the washing method however depends on the solubility of the target compounds and the operating conditions. Another method is addition of sodium hydroxide or calcium oxide to react with chlorine compounds, forming water-soluble salts that can be easily removed. Also, another method is to subject the coal or coke to high-temperature gasification processes, such as partial oxidation or pyrolysis. These processes can break down the chlorine compounds and organochlorines, converting them into gases that can be separated from the desired coke product. Any of these methods you choose may depend on factors, including the specific composition of the coal or coke, the desired purity level, and the economic feasibility of the chosen approach.
