  • Patent number: 11293310
    Abstract: A steam network assembly for a plant including an ammonia-producing unit and a urea-producing unit, including a high-pressure steam line, two medium-pressure steam lines and first and second turbines supplied with high-pressure steam by the high-pressure steam line; wherein the first turbine is a condensing-type turbine with extraction into one of the two medium-pressure steam lines, and is configured to deliver power to a syngas compressor in the ammonia-producing unit of the plant, and the second turbine is a counter-pressure type turbine with extraction connected to the two medium-pressure steam lines and is configured to deliver power to a CO2 compressor in the urea-producing unit of the plant. A method to distribute high-pressure steam in a steam network assembly for a plant including an ammonia-producing unit and a urea-producing unit and a method to revamp the steam network assembly for a plant including an ammonia-producing unit and a urea-producing unit.

  • Patent number: 6739454
    Abstract: Collector compositions of a mixture of a C6 to C22 fatty hydroxamic acid and an oil for use in a method the removal of impurities from mineral ores by the froth flotation method. The collectors are prepared by reacting an ester of a C6 to C22 fatty acid with a hydroxylamine salt and a base in the presence of an oil and water to produce an alkyl hydroxamate salt; acidifying the alkyl hydroxamate salt, forming an organic layer and an aqueous layer, wherein the organic layer contains a C6 to C22 fatty hydroxamic acid substantially free of starting esters and hydrolysis and transesterification products of the ester; and separating the organic layer from the aqueous layer to provide a collector composition of the C6 to C22 fatty hydroxamic acid and the oil.
