Balcones Cement

The Polaris membrane carbon capture FEED study evaluated a full-scale retrofit of Membrane Technology and Research’s membrane-based post-combustion capture system at CEMEX’s Balcones cement plant in Texas, targeting Kiln 2 flue gas. The design was developed under a US DOE NETL award and completed by MTR with Sargent & Lundy providing balance-of-plant engineering. The system was sized to treat the full Kiln 2 exhaust stream and capture approximately 2,247 short tons of CO₂ per day, equivalent to roughly 75 percent of kiln emissions, with a planned operating life of 25 years. Captured CO₂ would be compressed to pipeline pressure and exported offsite for geological storage or enhanced oil recovery. The FEED scope included process integration, flue gas ducting tie-ins, cooling and water systems, power supply upgrades, wastewater treatment, and site layout, with the objective of producing an AACE Class 3 cost estimate and advancing the project toward commercial deployment readiness
