摘要

We know that increasing the water content in coal tar above 4% and the ash content above 0.1 % hinders its processing: soda consumption is increased; greater heating is required in dehydration; and it is impossible to comply with standards regarding the ash content in pitch coke and electrode pitch. Recently, the trend has been to introduce a centrifuge ahead of the final tar store in systems for conditioning coal tar.
