Advanced Reactor Design for Integrated WGS/Pre-Combustion CO2 Capture

Performer: TDA Research Inc.

Project No: FE0012048

Project Scope and Technology Readiness Level

In the first six months, detailed computational fluid dynamics (CFD) modeling of the combined water-gas shift (WGS)/pre-combustion CO2 capture reactor system will be performed to optimize the heat integration to maximize the carbon monoxide (CO) conversion and CO2 capture, as well as to fabricate the advanced reactor designs. Modification of the AspenPlus™ model developed by the University of California Irvine under previous studies conducted for DOE/NETL will be used as the reference IGCC plant and gasification-based liquids production cases using conventional CO2 capture technology. In the second half of the project, bench-scale tests with the advanced reactors using simulated synthesis gas will be used to validate the CFD modeling results. A system analysis will be completed for the IGCC case using optimized gasifier steam-to-oxygen ratio to increase syngas hydrogen (H2)/CO ratio and evaluate the impact on overall IGCC plant efficiency and the gasification based liquids production case when using TDA’s combined WGS/pre-combustion CO2 capture technology with heat integrated reactors. The project will also demonstrate the key aspects of the process using coal-derived synthesis gas from a yet-to-be-determined source. Pall Corporation will collaborate with TDA to optimize the porous stainless-steel modules for steam introduction and provide the tubes for fabrication. Pall will also review the results of the CFD modeling and provide engineering consultation. The expected results of this project are the demonstration of an advanced CO2 capture system that can be efficiently added to IGCC power plants and gasification-based liquids (methanol and/or diesel) production to increase the hydrogen content, and generation of a system analysis showing a net increase in plant efficiency by 3-5 percent when compared to Selexol™-based plants with a cost of electricity increase of less than 10 percent as compared to IGCC without carbon capture and storage.

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".
