Pre-Combustion Carbon Capture

Commercial Applications

The typical application for pre-combustion capture would be an Integrated Gasification Combined Cycle (IGCC) plant. The process involves coal gasification or steam reforming followed by shift to produce H₂ and CO₂. The feedstock could be any from a variety of fuels. With CO₂ capture, the gasifier would normally operate in an oxygen-blown mode. The syngas from the gasifier is shifted to produce H₂ & CO₂.

An advantage of pre-combustion carbon capture over post-combustion capture is that the syngas is at a higher pressure and also has a higher concentration of CO₂, 15-60%. A physical solvent is typically used to separate the CO₂. The syngas could then undergo further processing for power generation and other applications like production of ammonia, FT fuels, etc.

KBR has extensive experience in Pre-Combustion CO₂ Capture through our Ammonia technology. The table below provides a listing of our recent experience in CO₂ Removal in Ammonia applications.

Instead of using a coal gasification process, the focus here is steam methane reforming to produce syngas. The syngas is shifted to produce H₂ for ammonia while the CO₂ is typically recovered for Urea production. KBR has also developed the Transport Gasifier TRIG™ technology. KBR is in a position to offer a combined package of our coal gasification technology and syngas processing with CO₂ capture.
