摘要： Asymmetric cellulose triacetate semipermeable membranes cast from a solution of cellulose triacetate having an acetyl content of at least 43 percent in a solvent mixture having a ratio of dioxane to acetone of at least about 1.5 to 1, which solution also contains a swelling agent in the form of a low molecular weight alcohol or a low molecular weight mono- or poly-basic acid. Solvent is evaporated from one surface of the cast film to form a dense gel layer and the film is immersed in water to provide an asymmetric semipermeable membrane having a high salt-rejection capability and good flux.

摘要： A flow meter for use with a fluid source includes a chamber of known volume, and level sensors for detecting fluid boundaries at either end of the known volume. A valve between the fluid source and chamber is opened at a defined time until fluid level within the chamber rises above the upper sensor, whereupon the valve is closed. As the fluid level falls past the upper sensor a second time level is measured, with both time intervals being terminated as the level falls to the lower level sensor. The average flow rate as the fluid falls between the two sensors is calculated by a computer, and the total volume is then calculated using the longer measured time interval. Flow rates over long time periods can be accurately measured.

摘要： Asymmetric reverse osmosis membranes are made from synthetic aromatic polyimides having a relatively high predominance of polar groups in the polymer backbone. A polar/non-polar group ratio of from 2:2 to 2:7 per imidized nitrogen link is required. Such membranes can be fabricated using conventional casting equipment by providing a solution of the polyimide in a good solvent and a poor solvent, the poor solvent being compatible with solution components at poor solvent/good solvent ratios of at least 1:1 up to about 7:1, casting a film of such solution, and partially evaporating the exposed surface of the cast film for 100.+-.30 seconds prior to gelation.

摘要： An improved method and apparatus for controlling large hydrocarbon-fueled fires contemplates the use of vapors produced by direct contact vapor generators to simultaneously cool the flames and deprive the fire of oxygen. A direct contact vapor generator accomplishes fire suppression by surrounding the fire with oxygen-free gases while cooling the flames with water vapor. The direct contact vapor generator is uniquely suited for extinguishing hydrocarbon-fueled fires because of its ability to produce oxygen-free gases and vapor in sufficient quantity to snuff out a fire of the magnitude of those occurring at the sabotaged wellheads in Kuwait in 1991 as well as oil field, oil storage facility, and oil refinery type fires.

摘要： An apparatus for generation of steam in a borehole for penetration into an earth formation wherein a spiral, tubular heat exchanger is used in the combustion chamber to isolate the combustion process from the water being superheated for conversion into steam. The isolation allows combustion of a relatively low pressure oxidant and fuel mixture for generating high enthalpy steam. The fuel is preheated by feedback of combustion gases from the top of the combustion chamber through a fuel preheater chamber. The hot exhaust gases of combustion at the bottom of the combustion chamber, after flowing over the heat exchanger enter an exhaust passage and pipe. The exhaust pipe is mounted inside the water supply line heating the water flowing into the heat exchanger. After being superheated in the heat exchanger, the water is ejected through an expansion nozzle and converts into steam prior to penetration into the earth formation. Pressure responsive doors are provided at a steam outlet downstream of the nozzle and close when the steam pressure is lost due to flameout.

摘要： Apparatus and method for generation of steam in a borehole for penetration into an earth formation wherein a downhole oxidant compressor is used to compress relatively low pressure (atmospheric) oxidant, such as air, to a relatively high pressure prior to mixing with fuel for combustion. The multi-stage compressor receives motive power through a shaft driven by a gas turbine powered by the hot expanding combustion gases. The main flow of compressed oxidant passes through a velocity increasing nozzle formed by a reduced central section of the compressor housing. An oxidant bypass feedpipe leading to peripheral oxidant injection nozzles of the combustion chamber are also provided. The downhole compressor allows effective steam generation in deep wells without need for high pressure surface compressors. Feedback preheater means are provided for preheating fuel in a preheat chamber. Preheating of the water occurs in both a water feed line running from aboveground and in a countercurrent water flow channel surrounding the combustor assembly. The countercurrent water flow channels advantageously serve to cool the combustion chamber wall. The water is injected through slotted inlets along the combustion chamber wall to provide an unstable boundary layer and stripping of the water from the wall for efficient steam generation. Pressure responsive doors are provided at the steam outlet for closing and sealing the combustion chamber from entry of reservoir fluids in the event of a flameout.

摘要： An apparatus for generation of steam in a borehole for penetration into an earth formation wherein feedback preheater means are provided for the fuel and water before entering the combustor assembly. First, combustion gases are conducted from the combustion chamber to locations in proximity to the water and fuel supplies. Secondly, both hot combustion gases and steam are conducted from the borehole back to the water and fuel supply. The water used for conversion to steam is passed in a countercurrent manner through a plurality of annular water flow channels surrounding the combustion chamber. In this manner, the water is preheated, and the combustion chamber is cooled simultaneously, thereby minimizing thermal stresses and deterioration of the walls of the combustion chamber. The water is injected through slotted inlets along the combustion chamber wall to provide an unstable boundary layer and stripping of the water from the wall for efficient steam generation. Pressure responsive doors are provided at the steam outlet of the combustor assembly. The outlet doors and fluid flow functions may be controlled by a diagnostic/control module. The module is positioned in the water flow channel to maintain a relatively constant, controlled temperature.
