Abstract: Urea is prepared by reacting ammonia and carbon dioxide in an apparatus comprising a vertical condensation and synthesis column and a stripper, to provide a urea synthesis solution comprising urea, unreacted ammonia, unreacted carbon dioxide and water. The urea synthesis solution is transferred from the top of the vertical condensation and synthesis column to the top of a stripper. Carbon dioxide is introduced into the bottom of the stripper and contacted with the urea synthesis solution, thereby separating the unreacted ammonia and the unreacted carbon dioxide from the urea, and providing a mixed gas comprising ammonia, carbon dioxide and water. The mixed gas is transferred into the bottom of the vertical condensation and synthesis column, where it is reacted with liquid ammonia injected into the bottom and a middle of the vertical condensation and synthesis column. The mixed gas and liquid ammonia are condensed and react to form urea, Uncondensed gases are absorbed in an absorbing medium, which is subsequently recycled to the bottom of the vertical condensation and synthesis column.

Abstract: The present invention relates to a process and apparatus for oxidizing an aqueous medium, which contains organic and/or oxidizable inorganic substances, at an increased temperature and an increased pressure for reducing the chemical oxygen demand of the aqueous medium to a predetermined desired level. The aqueous medium is introduced into a tubular reactor with an oxygen-containing medium. The tubular reactor contains a mechanism for dispersing bubbles of gaseous oxygen. The reactor contains sections through which the mixture of aqueous medium and oxygen containing medium serially flows. A degree of back-mixing in any one of the sections is equal to or less than the degree of back-mixing of an upstream section and the farthest downstream section has a smaller degree of back-mixing than the farthest upstream section.

Abstract: Methods and devices for controlling the reaction rate of a hydrocarbon to an acid or other intermediate oxidation product by pressure drop rate adjustments. The pressure drop rate measurements arc conducted at predetermined time intervals, after stopping the feeding and exiting of gases. The pressure drop at a predetermined time interval is measured or the time it takes for the pressure to drop by a certain degree. Adjustments are then made in one or more temperature, feeding rates of hydrocarbon, solvent, catalyst, promoter, and the like until the pressure drop rate and the reaction rate fall within desirable predetermined limits.

Abstract: Methods of making intermediate oxidation products by atomizing a first liquid (in the form of droplets) containing a reactant into a gas containing an oxidant in a manner to form an intermediate oxidation product different than carbon monoxide and/or carbon dioxide. The oxidation is controlled by monitoring the pre-coalescing temperature (temperature of the droplets just before they coalesce into a mass of liquid), or transient temperature difference (difference between the pre-coalescing temperature and the temperature of the droplets just before atomized), or transient conversion (conversion taking place in the time interval between the formation of the droplets and their coalescence into a mass of liquid) or a combination thereof.
