Abstract: A method for removing a contaminant from a fluid feed stream containing the contaminant. The method includes the steps of providing a feed stream and heating it in a first step to at least partially remove some of the contaminants and recover energy from a concentrate and distillate generated. Further heating the feed stream in a second heating step in a heated separator generates a saturated vapor fraction and a concentrated liquid contaminant fraction. The vapor fraction may be compressed to generate a temperature differential in the reboiler exchanger with the vapor fraction being passed into contact with a reboiler exchanger to provide a stream of condensed vapor from the reboiler. The stream may be circulated through the reboiler exchanger and the heated separator to maintain from about 1% to about 50% by mass vapor in the stream. The apparatus includes a unique configuration of a vapor compressor, heated separator in combination with a forced circulation circuit to generate the decontamination result.

Abstract: A compressed natural gas (CNG) transportation system designed to operate at or just below ambient temperatures, that is either ship-based, truck-mounted, or modular for container transportation. The system is an alternative to LNG, pipeline, or conventional CNG transportation systems, where the foregoing modes of transportation are not practical or feasible. The use of composite pressure vessels provides a critical advantage over conventional CNG concepts that use steel or steel lined pressure vessels. The rupture characteristics of composite pressure vessels exceed those of conventional steel or steel lined pressure vessels. The substantial weight reduction of pressure-equivalent composite pressure vessels overcomes the weight-related problems associated with steel or steel lined pressure vessel concepts. The corrosion resistance of composite pressure vessels allows for the transportation of raw CNG and or compressed natural gas liquids (CNGL) which are most often corrosive.

Abstract: A process for the preparation of potassium sulfate, sodium bicarbonate and sodium carbonate. The process involves the treatment of potash brines by the reaction of sodium chloride and potassium chloride with calcium sulfate and sodium sulfate. Syngenite precipitate (CaSO4.K2SO4&khgr;H2O) is produced and a first filtrate containing sodium chloride and potassium chloride. The syngenite precipitate is reacted with ammonium bicarbonate at between 70° C. and 100° C., with the result being calcium carbonate precipitate and a second filtrate containing ammonium sulfate and potassium sulfate. The second filtrate is cooled to a temperature of between 20° C. and 50° C. and treated with potassium chloride. A potassium sulfate precipitate results. The sodium bicarbonate is precipitated from the first filtrate by the addition of ammonium bicarbonate to the first precipitate. The sodium bicarbonate may be calcined to form sodium carbonate.

Abstract: A method of wet granulation of fertilizer and other materials into granules. The method involves formation of the granule directly on the pan from the feedstock without intermediate steps or the use of seed materials. The result is a product having a completely uniform cross section. The feedstock is initially in the size distribution of −150 mesh with 90% or greater in the size range of 200 mesh. Moisture is maintained to facilitate a steady process without cycling. The method has the advantage of allowing granulation of materials either known to be hazardous or inherently difficult to granulate in a safe and expedient manner.

Abstract: A method for separating contaminants from a aqueous source containing contaminants. In one embodiment, the method involves the use of a high powdered oxidant dissolved within the aqueous system. The gas is dissolved within a reservoir in the aqueous solution and the pressure within the reservoir is controllable. This allows maximum contact of the oxidizing dissolved gas with the contaminant material. Once oxidized, the outlet of the reservoir is adapted to permit hydraulic cavitation. The net effect of the cavitation is to induce a foam formation which foam transports a floc into a separate phase from the aqueous solution. In this manner, the process is effectively a dissolved oxidizing gas mass transfer process. In another embodiment, the process may be augmented by electrocoagulation. This involves the use of an electric cell which is disposed within the reservoir containing the oxidant material.

Abstract: Granulated particles by making use an initial feedstock having particle size of −150 mesh and 90% or greater particle size of 200 mesh. The feedstock may be contacted in a pan granulator which includes a minor amount of nucleating material of about −35 mesh. Binder is introduced into the pan granulator to progressively layer the feedstock material onto the nucleating to form a final granular fertilizer or other product in any desired size distribution. The method by which the granules are formed is interruptible and is particularly useful for forming granules having a plurality of layers of differing material. The granules, by formation with dust feedstock and in the absence of seed material, lack a core and therefore include the maximum amount of tightly packed feedstock. This results in substantial increases in the break strength of the granules with uniform homogeneous cross-sections.

Abstract: Fertilizer granulation method for incorporating urea directly into the matrix of fertilizer pellets. The process involves introducing the urea in a liquid form into the matrix and then progressively cooling the mixture of pellet and urea to recrystallize the urea within the matrix of the pellet. The result is a substantially harder particle relative to pretreatment hardness, reduced solubility for longer lasting pellets and substantially reduced dust and other handling problems of the formed pellets.

Abstract: A process for obtaining paclitaxel and other taxanes from a source containing taxanes. The process involves extracting taxane compounds from the source into an organic solvent and passing this composition through a distribution chromatography column and eluting taxane compounds with the dry distribution column. The eluted taxane compounds are isolated by further processing techniques.

Abstract: A valve body for use in an automatic overdrive transmission where the hydraulic fluid passages are blocked in selected locations in the body. The blockages result in increased pressure in the free passages and redirection of fluid flow such that the reverse clutch assembly is operable in third gear. By this procedure, the torque capacity of the transmission is increased.

The apparatus is elevated at one end to provide a slide for the foodstuff with the channels converging from one end of the apparatus to the other. As the foodstuff slides down a channel, the former is oriented from a random position to an ordered vertical disposition.

Abstract: A filter element adapted for use in reciprocating drilling shafts. The element includes a flexible filter material wrapped about a biasing member and opposed rigid ends. The biasing member returns the filter to an elongate form after compression and spaces the filter material from the shaft. The result is substantially less debris contacting the shaft to thus prevent damage thereto and operational impedance.

Abstract: A guitar is disclosed which is adapted for use with a battery power source and having a CPU and a memory including preprogrammed chord tables and melody tables. The guitar provides electro conductive strings and frets and a system for recognizing finger positioning by a user. The vibration of the strings is picked up by piezo elements and amplified. By making use of the piezo elements the intensity of the vibration by its velocity can be preserved and the envelope of sound for a note/chord remain commensurate with the intensity intended by the user.

Abstract: There is disclosed a process for recovering sodium bicarbonate and forming ammonium sulfate from a source containing sodium sulfate. The method involves contacting the sodium sulfate in solution with carbon dioxide and a compound containing ammonia. Sodium bicarbonate is precipitated in high purity form from the solution. It is important to maintain the temperature of the source solution at or above 32.degree. C. This provision eliminates contamination of hydrates or ammonium bicarbonate components. The filtrate of the sodium bicarbonate reaction can be further processed to yield an ammonium sulfate product in the concentrated liquid or precipitated form in high purity. The basic process can be expanded to be combined with a conventional Claus process for sulfur recovery as a Tail Gas Unit, or can be further employed in a wet and dry scrubbing process for FGD schemes.
