CO2 compression report. American Electric Power Mountaineer CCS II Project: Phase 1

2nd December 2011

Topic(s): Carbon capture use and storage (CCUS), CO2 capture

The study focused on commercially available, integrally-geared, inter-cooled, gas compression systems. The scope included all of the equipment required to compress and condition the captured CO2 for sequestration. Geologic characterisation information and actual operating data from the Mountaineer Chilled Ammonia Product Validation Facility (PVF), which operated from 2009 to 2011, provided injection parameters on which to base the design for the commercial-scale compression system. Equipment arrangements, auxiliary power demands, balance of plant integration, and capital and operating costs were considered in the evaluation of each compression system.

In the end, two arrangements were considered technically and economically feasible for implementation on the commercial-scale system. Further technical investigation in Phase II of the project would determine which arrangement would ultimately be selected. Both utilise compression of the CO2 to an intermediate condition, followed by variable-speed pumping to the final desired injection conditions. The compressor-pump arrangement allows for greater flexibility and higher operating efficiency throughout the life of the well, which is important based on the expected variability in injection pressure over the life of the injection wells – a key takeaway from the PVF operation effort, and design basis driver for the commercial-scale project.
