Removing mercury vapor from gas, e.g. produced by incinerator, involves activating dust filter with amorphous selenium or sulfur

摘要

A method for removing mercury vapor and dust from a metal-containing gas involves using a textile filter containing selenium or sulfur, resulting in the formation of stabile metal selenides. The filter material is activated with amorphous selenium or sulfur and the resulting metal selenides, metal sulfides and dust are continuously removed together. ides, sulfides and dust are continuously removed together.
