Carbon capture, from screening to design

Aspen bolts emissions accounting on as an afterthought. MaximaLabs recomputes cost and carbon together, on the same model, every time you change a spec.

Post-combustion capture then compression to pipeline pressure — the real energy cost after capture, on the same canvas.

Electrolyte thermodynamics that actually converge

A bounded electrolyte-NRTL model resolves the CO₂–MEA–H₂O speciation with a Davies activity correction — validated against Jou-Otto-Mather 30 wt% MEA loading data (log-AAD < 0.45).
