Abstract
A method and arrangement for removing solid particles and tar component from carbon monoxide gas. In the method, carbon monoxide gas is conducted from a ferroalloy smelting furnace () to a gas scrubber (), the carbon monoxide gas is scrubbed in the gas scrubber () by a liquid medium for removing part of the solid particles, the carbon monoxide gas is conducted from the gas scrubber to a blower (), the flow rate of the carbon monoxide gas is increased by the blower (), and the carbon monoxide gas is conducted to a particulate filter () and the remaining solid particles are essentially filtered in the particulate filter () from the carbon monoxide gas. Prior to conducting the carbon monoxide gas to the particulate filter (), it is conducted to a particle feeder (), where finely divided adsorbent particles (A) are fed in the carbon monoxide gas for adhering the tar component on the surface of the adsorbent particles, and the carbon monoxide gas flow containing adsorbent particles is conducted to the particulate filter (), in which case the tar component adhered on the adsorbent particles is discharged in the particulate filter ().
