Abstract: A flexible container (10) is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments (18, 20, 22) separated by preferentially peeled seals (24, 26) in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The peelable seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The container is fillable with a single component liquid medicament which may be susceptible to sloshing or turbulence. Turbulence is minimized by eliminating the internal gaseous head space by initially forming the head space with a low molecular weight gas such as helium.

Inventor: RONNING RICHARD L
IPC: B01D53/62
Filed: 2008-03-20
Granted: 2016-05-24
Abstract: A method and apparatus are provided for reducing the VOC and CO content of dryer offgas that is discharged into the atmosphere from a moist organic product drying process using thermal oxidizing apparatus that includes a furnace, mixing chamber, thermal oxidizer, tempering chamber, and an indirect gas-to-gas heat exchanger. The dryer offgas is separated into two portions, with a larger portion being preheated by indirect heat exchange with the hot gaseous output from the thermal oxidizer. The non-preheated portion is directed to a rotary waste heat evaporator in which moisture is removed therefrom. The preheated portion is recycled to the hot gas inlet of the dryer and serves the function of dryer heat transfer media. By removing moisture from the non-preheated portion of the offgas that is directed to the thermal oxidizing apparatus, simultaneous achievement of thermal oxidizer temperatures of1600°F or greater, and an adequate oxygen concentration of 5% by volume is achieved for optimized thermal oxidation of carbon monoxide and volatile organic compounds.

Abstract: Hydrocarbon-soluble molybdenum catalyst precursors include a plurality of molybdenum cations that are each bonded with a plurality of organic anions to form an oil soluble molybdenum salt. A portion of the molybdenum atoms are in the 3+ oxidation state such that the plurality of molybdenum atoms has an average oxidation state of less than 4+, e.g., less than about 3.8+, especially less than about 3.5+. The catalyst precursors can form a hydroprocessing molybdenum sulfide catalyst in heavy oil feedstocks. The oil soluble molybdenum salts are manufactured in the presence of a reducing agent, such as hydrogen gas, to obtain the molybdenum in the desired oxidation state.  Preferably the reaction is performed with hydrogen or an organic reducing agent and at a temperature such that the molybdenum atoms are reduced to eliminate substantially all molybdenum oxide species.
