MT CCS II Phase I Technical Approach Operations (cont.) AEP and Alstom collaborated to practically address process variability in the commercial scale design PVF Lessons Learned Integrated design workshops Effective communication to develop . Detailed flue gas specifications with expected ranges for significant characteristics . Expected quantities and quality of makeup water to properly identify equipment sizing, treatment needs, HXR capacities, etc. Expected quantity and quality of available steam and how the steam supply is affected by load changes, ambient conditions, etc. A suite of material and energy balances . Depicting main generating unit variability AND CAP modeled process variability with respect to changes in load, ambient conditions, etc. Goal: Maximize efficiency and minimize complexity of operations.
