Carbon Capture Costs: FEED & pre-FEED Cost Reports

Linde Inc., with Linde Engineering Americas and BASF, is conducting an initial engineering design for a 3,500 tonnes/day CO₂ capture plant using Linde-BASF’s advanced aqueous amine technology at a Linde-owned steam methane reforming facility. The project will define integration options, establish project requirements, optimize process design, and develop engineering, cost, and schedule packages. BASF will provide the technology design, LEA will deliver detailed engineering and constructability assessments, and Linde will lead techno-economic, environmental, and safety analyses in coordination with the SMR plant operators.

Membrane Technology and Research Inc., with Technology Centre Mongstad, Dresser-Rand, Trimeric Corporation, and WorleyParsons/Advisian, is scaling up its advanced Polaris™ membranes for post-combustion CO₂ capture and testing them at engineering scale at TCM in Norway. The Polaris membranes, about 20 times more permeable than prior commercial versions, use a patented selective recycle design to boost CO₂ concentration in flue gas and lower capture costs. The project will design, build, and operate a modular membrane system for a six-month field test, including performance verification, steady-state operation, techno-economic updates, and integration studies with advanced compression technology.

The Red Trail Energy (RTE) ethanol facility in Richardton, North Dakota, is implementing a CO₂ capture and liquefaction system designed by Trimeric. The system captures CO₂ from fermentation, compresses it to ~350 psig, dehydrates and liquefies it using an ammonia refrigeration loop, and purifies it via distillation to remove oxygen and other gases. The liquid CO₂ can be stored for sale or geologic sequestration. The facility is designed to process 587 tonnes/day (scalable to 675 tonnes/day), with nearly complete CO₂ recovery.
