ENHANCED SURFACTANT POLYMER FLOODING PROCESSES FOR OIL RECOVERY IN CARBONATE RESERVOIRS
A composition for use in surfactant polymer flooding processes in a carbonate reservoir, the composition comprising a surfactant, the surfactant operable to reduce interfacial tension, a polymer, the polymer operable to increase the viscosity of the composition, and a tailored water, the tailored water operable to alter a wettability of the in-situ rock, where the tailored water has a total dissolved solids of between 5,000 wt ppm and 7,000 wt ppm, where the total dissolved solids comprises a salt, where the composition has a viscosity between 3 cP and 100 cP.
LONG-TERM FIRE RETARDANT WITH MAGNESIUM SULFATE AND CORROSION INHIBITORS AND METHODS FOR MAKING AND USING SAME
A forest fire retardant composition contains a retardant compound that includes a halide salt, a non-halide salt, a metal oxide, a metal hydroxide, a sulfate salt, or combinations thereof. The forest fire retardant composition may include at least one anhydrous salt and at least one hydrate salt. The sulfate salt may be magnesium sulfate. The magnesium sulfate hydrate has a formula MgSO.sub.4(H.sub.2O).sub.x, where x is about 1 to about 11. For example, x may be equal to at least one of 1, 2, 3, 4, 5, 6, 7, 9, 10 or 11. The composition may be in the form of a dry concentrate, a liquid concentrate, or a final diluted product. The final diluted product is effective in suppressing, retarding, and controlling forest fires while exhibiting corrosion resistance and low toxicity.

Method and system for neutralizing asbestos
The invention relates to a system for neutralizing asbestos, said system comprising a mobile neutralization unit (200) comprising: an asbestos waste sorting module (225), an asbestos grinder (255) and a hot acid bath (250) for rendering asbestos inert. Preferably, the asbestos waste sorting module comprises: a window with glove boxes; and a conveyor for transporting the asbestos waste in front of the window. In embodiments, the system comprises a means for containing the atmosphere within the mobile neutralization unit and/or the hot acid bath (250) of the mobile neutralization unit (200) comprises sulfuric acid.
Process for recovering components from pickling acid residue
A novel process for treating and recovering valuable metals and other components from pickling acid residue (PAR) has been developed. The metals and other components are recovered by neutralizing the pickling acid residue using a magnesium compound or a mixture of magnesium compounds, and separating components of the resulting mixture (metals and sulfates) into products that can be reused, such as magnesium sulfate, nickel sulfate, iron and chromium phosphate, or various metal hydroxides or oxides.
Device and method for making a hollow tube of micron-sized crystalline magnesium sulfate
A device for creating hollow tubes of crystalline magnesium sulphate sized a micron pertains to the production technology for inorganic micron-scale materials. The device consist of two halogenation tanks, a solar collector, a temperature-controlled crystallization chamber, a centrifuge, a conveyor belt, and a dryer. The solar collector is connected to a heat pipe at the bottom of a brine pool to form a circulation path. Said method is to convert high magnesium brine into saturated brine with a Mg.sup.2+:Na.sup.+ mass ratio between (8?15):1 by a brine blending operation at a temperature of 60? C.?90? C. it is controlled to be cooled and crystallized at a cooling rate of 0.6?2.0? C./min, solid-liquid centrifugal separation is carried out when it is cooled down to 40?48.5? C., and the solid phase is dried at a temperature of 48.5?70? C., and finally micron-sized crystalline magnesium sulfate hollow tubes are obtained.
