Multi-contaminant control granular-bed filter
The objective of this phase of the Moving Granular Bed Filter (GBF) Development Program is to develop a GBF for the control of particulates and other contaminants found in high pressure and high temperature coal-derived gas streams. The filter should be able to remove particulates and one or more contaminants such as sulfur compounds, nitrogen compounds, alkali compounds, halogenated compounds, heavy metals and tars. The multi-contaminant control granular bed filter should be applicable to reducing and/or oxidizing conditions. This paper discusses limestone for sulfur control; clay for alkali control; trace metal control; filter media preparation, characterization, and evaluation; pilot scale testing; and cost estimate for production GBF multi-contaminant filter medium.
