Impurity and phase-transition analysis
Evaluate where composition and operating conditions threaten a single-phase assumption.
CCUS measurement and transport
A CO₂ stream is only simple until the impurities matter.
DigitronX studies how composition, pressure, temperature, phase behavior, instrumentation, and model uncertainty combine in CCUS transport and custody transfer.
Why it is difficult
Measurement uncertainty is coupled to thermodynamic uncertainty.
A custody-transfer quantity is not produced by an instrument alone. It depends on the measurement equation, composition data, equation of state, phase condition, dynamic response, calibration, and the uncertainty assigned to each element.
Impurities can shift density, phase boundaries, compressibility, and transport behavior. Near a transition, seemingly modest uncertainty can change the physical interpretation of the stream. The certificate must therefore be supported by a chain of evidence, not merely a reported meter value.
Relevant foundation
CO₂/H₂S chemistry meets field measurement and stiff computation.
Richard C. Aiken's published work includes selective H₂S removal from CO₂, high-pressure gas purification, stiff parameter estimation, and two-phase field measurement. DigitronX brings these formerly separate strands together around the operational demands of CCUS.
Current directions
Custody-transfer uncertainty
Connect instrument, composition, thermodynamic, and model uncertainty in one auditable framework.
Fast transient prediction
Use asymptotic structure to support estimates on an operational rather than simulation timescale.
Validity and fallback logic
State when a reduced model is trustworthy and when a higher-fidelity calculation is required.
