    Excess pCO2 and carbonate system geochemistry in surface seawater of the exclusive economic zone of Qatar (Arabian Gulf) by Connor, Izumi

    Published 2022
    “…The slope suggests that removal of C as CaCO3, organic matter (CH2O) or gas exchange (FCO2) is occurring with a ratio of ΔCaCO3/(ΔCH2O or FCO2) = 1:2.86. The tracer Alk*, defined as the deviation of potential alkalinity (AP) (where AP = TA + 1.26 [NO3]) from conservative potential alkalinity ((ApC), (ApC = S Ap′S′ where A'P and S′ are mean values for the whole surface ocean) has values primarily determined by CaCO3 precipitation and dissolution. …”

    Prospects Of Amino Acids And Ionic Liquids As Natural Gas Hydrate Inhibitors For Offshore Flow Assurance by Qureshi, M. Fahed Aziz

    Published 2018
    “…The inhibitors tend to show better hydrate inhibition effect at low pressures (40 bars) and their inhibition effect decreases as the pressure rises. At the same concentration (10 wt%), the ammonium-based ionic liquid [EA][Of] provided the inhibition effect similar to MEG and at the higher concentration (20 wt%) the amino acid glycine provided better hydrate inhibition effect than the MEG. …”
