摘要： Various embodiments disclosed relate to methods and apparatuses for determining a minimum miscibility pressure of a fluid with and oil composition. In various embodiments, the method can include placing a fluid into a pressure chamber at a first pressure. The pressure chamber can include at least one capillary tube having one end disposed in an oil composition in the pressure chamber. The fluid can include at least one of a gas, a liquid, and a supercritical fluid. The method can include measuring a height of the oil composition in at least one of the capillary tubes. The method can include repeating the measuring for at least one cycle using a second pressure different than the first pressure. The method can include determining the minimum miscibility pressure of the oil composition with the fluid by extrapolating the pressure at a height of the oil in the at least one capillary tube of zero from the two or more measurements of the height of the oil composition in the at least one capillary tube.

摘要： The method of the present invention is adapted to manipulate the chemical properties of water in order to improve the effectiveness of a desired chemical process. The method involves heating the water in the vessel to subcritical temperatures between 100.degree. to 374.degree. C. while maintaining sufficient pressure to the water to maintain the water in the liquid state. Various physiochemical properties of the water can be manipulated including polarity, solute solubility, surface tension, viscosity, and the disassociation constant. The method of the present invention has various uses including extracting organics from solids and semisolids such as soil, selectively extracting desired organics from nonaqueous liquids, selectively separating organics using sorbent phases, enhancing reactions by controlling the disassociation constant of water, cleaning waste water, and removing organics from water using activated carbon or other suitable sorbents.

摘要： An injector for use with a capillary supercritical fluid chromatography (SFC) apparatus includes an operable four-port switching valve having a body portion and a rotor rotatably mounted within the body portion. The rotor has a hole therethrough which will selectively register with pairs of aligned ports. Thus, the rotor is rotatable between a loading position, wherein a first and third port are in communication, and a chromatographic position, wherein a second and fourth port are in communication. A first tubular member extends from the third port and is connected to a retention gap, which is in turn connected to an end of a capillary SFC column. A bypass tube connects the fourth port to the first tubular member. The loading position of the rotor and the first tubular member form a straight pathway to permit a needle to be inserted therethrough into the retention gap to inject a sample. A method is also disclosed whereby said injector permits the venting of a sample solvent from the injector by cycling the rotor, between the chromatographic and loading positions for predetermined time intervals.
