Hot/Warm Gas Cleanup

PDF Version Also Available for Download.

Description

Using regenerable sorbents and transport or fluid-bed contacting, the Gas Process Development Unit (GPDU) at NETL-Morgantown will be used to demonstrate the process feasibility of removing sulfur from coal gasification or other fuel gas streams at temperatures above dew point of the gas. This technology, also known as hot or warm gas desulfurization, is expected to remove sulfur to concentrations lower than conventional systems at comparable cost. The project was constructed under the U.S. Department of Energy (DOE) Integrated Gasification Combined Cycle (IGCC) power system program and is an ''enabling technology'' in the Vision 21 program. The GPDU was designed ... continued below

Description

Using regenerable sorbents and transport or fluid-bed contacting, the Gas Process Development Unit (GPDU) at NETL-Morgantown will be used to demonstrate the process feasibility of removing sulfur from coal gasification or other fuel gas streams at temperatures above dew point of the gas. This technology, also known as hot or warm gas desulfurization, is expected to remove sulfur to concentrations lower than conventional systems at comparable cost. The project was constructed under the U.S. Department of Energy (DOE) Integrated Gasification Combined Cycle (IGCC) power system program and is an ''enabling technology'' in the Vision 21 program. The GPDU was designed to be the smallest scale research and development facility capable of providing viable scale-up design data for new integrated transport or fluid-bed desulfurization processes. With the capability to test at process conditions representative of anticipated commercial applications in terms of temperatures, pressures, major compositions, velocities, and sorbent cycling, the unit is expected to generate important information on process control, configuration, and sorbent suitability. In this way, the GPDU fills a strategic role between past/current small-scale testing and large-scale demonstrations. A primary objective of the project is to gain insight into which reactor combination (i.e., both transport, both fluid bed, or mixed) is more suitable for desulfurization technology and why. Assuming process feasibility is demonstrated, this guides future development or commercial ventures by answering the question of what to build, and provides performance and scale-up data (e.g., required transport reactor densities). Another important objective, which naturally derives from the process development activities, is demonstration of sorbent suitability and readiness for commercial deployment (e.g., sorbent attrition and cycle life). In this sense, the GPDU can serve as a final testing ground to reduce the risks of large-scale sorbent failure.
