Binary system of alkyl polyether carboxylate and quaternary ammonium with ultra-low interfacial tension at high temperature and a wide range of salinity

To obtain the ultra-low interfacial tension foam flooding system for the real reservoir condition of high-temperature and high-salinity, foam properties and dynamic interfacial tension had been performed by Ross-miles test and spin drop tension meter respectively. Ten types of surfactants were screened by foamability, stability and interfacial tension (IFT) at 85°C, high-salinity with 800 mg/L divalent cations and 30000 mg/L total mineralization. The AOS, AESO and 20YB were selected to compose further anion-nonionic mixture system. Due to AOS had excellent foam properties, AESO could achieve low interfacial tension and 20YB could improve the film quality. Through series complex study, the ultra-low interfacial tension (10-4 mN/m order of magnitude) foam system was obtained with the composition of 0.15% wt AOS+0.15% wt AESO+0.11%~0.012% wt 20YB for high-temperature and high-salinity, which V foam was 240-235 mL and t 0.5 was 180-190 min. In addition, the synergistic effect of these surfactants had been described.

Ratios of internal cation mobilities in the molten binary system (K,Rb)NO3 have been measured with the Klemm method in a wide range of concentration (0.0537 < χRb< 1.00; χRb denotes mole fraction of RbNO3) and temperature (603 K < T < 783 K). From these and available data on the densities and conductivities, the internal mobilities of the two cations, bK and bRb, have been calculated. At high temperature and high ;cRb, the Chemla effect has been observed, whereas in previous similar experiments * the Chemla effect had not been observed. Except for xRb > 0.9, bK can be expressed by bK = [A /(V - V0)] exp (- E/RT), where V is the molar volume; A, E and V0 are constants having almost the same values as in the molten binary system (K,Cs)NO3.

Reduce Emissions

Countries in the world now are trying best to conserve energy and reduce emissions, at the meantime, efficient actions are taken to tackle with global&#160;warming. Emission reduction&#160;of main greenhouse gas CO2&#160;can be achieved efficiently via CO2 geological storage, in terms of CO2 saline aquifer storage. The gas&#8211;liquid&#8211;solid interactions such as interfacial tension determines the injectability, sealing capacity and safety of this scheme. In order to better predict the storage capacity to evaluate the storage safety, this work aims at carrying out the numercial modelling work on the interfacial tension of CO2&#8211;water/brine binary system under the reservoir temperatures and pressures condition.&#160;A linear relationship between the increase in average interfacial tension and molality was observed and it is a function of the ionic type. Finally, modified empirical correlations based on experimental data in the literature, using only few regression coefficients with a relatively low error for most of the experimental data in the literature, were presented to estimate the CO2&#8211;water/brinebinary system interfacial tensions under wide range of temperatures, pressures, and the ionic strength..&#160;

Further Development

Ceramics, such as Al2O3 and SiC have numerous current and potential uses in applications where high temperature strength, hardness, and wear resistance are required often in corrosive environments. These materials are, however, highly anisotropic and brittle, so that their mechanical behavior is often unpredictable. The further development of these materials will require a better understanding of the basic mechanisms controlling deformation, wear, and fracture.The purpose of this talk is to describe applications of TEM to the study of the deformation, wear, and fracture of Al2O3. Similar studies are currently being conducted on SiC and the techniques involved should be applicable to a wide range of hard, brittle materials.

In recent years an increasing emphasis has been placed on the study of high temperature intermetallic compounds for possible aerospace applications. One group of interest is the B2 aiuminides. This group of intermetaliics has a very high melting temperature, good high temperature, and excellent specific strength. These qualities make it a candidate for applications such as turbine engines. The B2 aiuminides exist over a wide range of compositions and also have a large solubility for third element substitutional additions, which may allow alloying additions to overcome their major drawback, their brittle nature.One B2 aluminide currently being studied is cobalt aluminide. Optical microscopy of CoAl alloys produced at the University of Missouri-Rolla showed a dramatic decrease in the grain size which affects the yield strength and flow stress of long range ordered alloys, and a change in the grain shape with the addition of 0.5 % boron.
