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 COcompressor 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.
