A method of classifying the water produced in the coke making process into a small amount of salt and a small amount of salt

摘要

In order to separate water obtained in a coking process into a small fraction with a high salt content and into a large fraction with a low salt content, raw gas is cooled in a receiver and is conducted through an electric filter before entering the pre-cooler. The condensate of the receiver and the flow of the electrofilter are conducted into the tar separator, while the condensate of the pre-cooler is only partly reintroduced in the receiver circuit and a low salt content residue is obtained. On the other hand, the aqueous phase of the tar separator is partly treated as a high salt content fraction; after coming out of the electric filter, the raw gas may also be fractionated in a plurality of pre-coolers.
