Warm Gas Multi-Contaminant Removal System
Performer: TDA Research, Inc.
Project No: SC0008243
Project Scope and Technology Readiness Level
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 will 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 optimal 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.
The Technology Readiness Level (TRL) assessment identifies the current state of readiness of the key technologies being developed under the DOE’s Clean Coal Research Program. This project has not been assessed.
The TRL assessment process and its results including definition and description of the levels may be found in the "2012 Technology Readiness Assessment-Analysis of Active Research Portfolio".
