Metakaolin—lime hydration products
Thermochimica Acta, 1984Abstract Four mixtures were prepared of weight ratios 80:20, 70:30, 60:40 and 50:50 of china kaolin/pure Ca(OH) 2 . Each mix was activated for 2 h at 800°C and then paste hydrated at room temperature and 100% RH for up to 28 days. The hydration products were studied by XRD as well as DTA and TG techniques.

Black Sea hydrates production value
2022Natural gas hydrates of Bulgaria and Romania in the Black Sea have been subject to studies by several European research projects. In this study, we have evaluated some well-known hydrate production methods. Thermal stimulation and adding chemicals are considered as not economically feasible.

Hydration products of calcium aluminoferrite
Cement and Concrete Research, 1983Abstract Hydration products of Ca2AlFeO5, steam cured at 72 C, have been identified using X-ray diffraction and Mossbauer spectroscopy. Iron-bearing phases are hydrogarnet Ca3FeyAl2−y(OH)12 with y = 0.22, and non-crystalline ferrihydrite Fe(OH)3.nH2O.

Hydrate Mitigation in a Deepwater Production System
SPE Offshore Europe, 1989Abstract Deepwater developments such as the one depicted in Fig 1 rely on production flowlines to carry raw, unprocessed reservoir fluid, called full wellstream (FWS) production, from wells to production facilities. As the search for reserves has taken the petroleum industry into deeper water and colder environments, the feasibility of ...
