Calcium, Magnesium andlor Sodium Bicarbonates (Soluble) + Hydrogen Cation Exchanger (Insoluble) = Calcium, Magnesium and/or Sodium Cation Exchanger (Insoluble) + Water + Carbon Dioxide (Soluble Gas).

The presence of methanol in the liquid water phase substantially increases the predicted carbon dioxide solubility in that phase. 

Probably the most important feature of the "wet" methanol hydrocarbon flash results in the enhanced carbon dioxide solubility in the liquid water phase. This would probably mean potentially more severe corrosion problems in the pipeline and associated equipment. The design and operation of the corrosion prevention system and program can be substantially improved.

For the calculations, averages of the results of the two 5. -equilibrium models of Ca2+ = 35 p.p.m., Mg2+ = 7 p.p.m., and alkalinity = 1.55 X 10 3 equiv./liter are used. Solubility data of Larson and Buswell (11), carbon dioxide solubility data of Hamed and Davies (2), and the carbonate ionization data of Hamed and Hammer (3) and Hamed and Scholes (4) are used. Linear interpolations are made for dolomite between pK(soly) = 16.3(5°C.) and 17.0(25°C.). Equations outlining the calcite and dolomite calculations are ... 

There are only few data sets of aqueous solubility for systems with hydrates (1) methane and ethane solubility in water as a function of temperature ramping rate (Song et al. 1997), (2) carbon dioxide solubility in water by Yamane and Aya (1995), (3) methane in water and in seawater (Besnard et al., 1997), (4) methane in water in Lw-H region [see Servio and Englezos (2002) and Chou and Burruss, Personal Communication, December 18,2006, Chapter 6], As a standard for comparison, Handa s (1990) calculations for aqueous methane solubility are reported in Table 4.3.

The feed can be many pumpable fluids, including suspensions, so the range of applications is wide. Organics can be stripped from aqueous streams such as fruit juices, fermentation broths, enzyme reaction mixes and waste water. Carbon dioxide soluble components can also be stripped from oils. Applications are seen to be especially appropriate in the flavors, pharmaceuticals, environmental, analytical and fine chemicals sectors. 

Another interesting result of carbon dioxide solubility in water is that it constitutes the basis for the phenomenon of spontaneous and violent liberation of dissolved C02 to the atmosphere in a stratified lake, as in the case of Lake Nyos in Cameroon mentioned above (see Section 6.1.3). When dissolved C02 seeps from a hydrothermal vent into a stratified lake, the pressure and low temperature favor the dissolution and saturation in the lower strata of the lake. Because of its high solubility, more than five volumes of C02 can dissolve in one volume of water. As for any other gas, however, its solubility depends on temperature and pressure, making the...

In the case of the water-wet foam floods, the carbon dioxide solubility which gave the best match to the secondary floods was 0.8 mol fraction, while a value of 0.7 gave the best match for the tertiary foam floods, as shown in Figures and 8. The best values for the oil-wet case were O.9 mol fraction for both the secondary and tertiary cases, as shown in Figures 9 and 10. 

Thus, in most cases a fit could be obtained with the inverted phases with caroon dioxide solubility in a narrower range than the range required of the mixing parameter if the normal phases were used and the mixing parameter was varied. On the other hand, the use of the inverted j ases with carbon dioxide solubility as the only parameter available does not make use of the other features of the Multiflood simulator such as the trapped oil curve and the simulation of the effects of fingering in the way shown successfully before.
