Warm Gas Multi-Contaminant Removal System

Project No: SC0008243

Project Description

TDA Research, Inc. is developing a high-capacity, low-cost sorbent that removes anhydrous ammonia (NH3), mercury (Hg), and trace contaminants from coal- and coal/biomass-derived syngas. The clean-up system will be used after the bulk warm gas sulfur removal step, and remove NH3 and Hg in a regenerable manner while irreversibly capturing all other trace metals (e.g., Arsenic, Selenium) reducing their concentrations to sub parts per million (ppm) levels. Current project plans include identifying optimum chemical composition and structure that provide the best sorbent performance for removing trace contaminants, determining the effect of operating parameters, conducting multiple-cycle experiments to test the life of the sorbent for NH3 and Hg removal, and conducting a preliminary design of the sorbent reactor.
