Title
(EN) STEAM NETWORK ASSEMBLY FOR A PLANT COMPRISING AN AMMONIA-PRODUCING UNIT AND A UREA-PRODUCING UNIT
(FR) ENSEMBLE RÉSEAU DE TUYAUTERIE DE VAPEUR D'INSTALLATION COMPRENANT UNE UNITÉ DE PRODUCTION D'AMMONIAC ET UNE UNITÉ DE PRODUCTION D'URÉE
Abstract
(EN)
The present disclosure provides a steam network assembly for a plant comprising an ammonia-producing unit and a urea-producing unit, comprising a high-pressure steam line (1), two medium-pressure steam lines (2, 3) and a first and second turbine (10, 12) supplied with high- pressure steam by the high-pressure steam line (1); wherein the first turbine (10) supplied with high-pressure steam by the high-pressure steam line (1) is a condensing-type turbine with extraction into one of the two medium-pressure steam lines (2), and is configured to deliver power to a syngas compressor in the ammonia-producing unit of the plant, and the second turbine (12) supplied with high-pressure steam by the high-pressure steam line (1) 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. The present disclosure also provides a method to distribute high-pressure steam in a steam network assembly for a plant comprising an ammonia-producing unit and a urea-producing unit and a method to revamp the steam network assembly for a plant comprising an ammonia-producing unit and a urea-producing unit.
