Abstract: front page image
(EN)Processes using multiple expansion turbines for efficient recovery of power from a plurality of very high pressure streams of superheated vapor are disclosed. Beneficially, processes of the invention use at least two classes of expansion turbines. Processes according to this invention are particularly useful for recovery of power from very high pressure streams of superheated steam in an olefins manufacturing process. Such streams are typically produced by thermal cracking of suitable petroleum derived feed stocks, and the olefins being produced and purified are typically ethylene and/or propylene.
(FR)L'invention concerne des procédés faisant intervenir plusieurs turbines de détente pour une récupération de puissance efficace à partir d'une pluralité de flux de vapeur superchauffée très haute pression. De manière avantageuse, les procédés de l'invention font appel à au moins deux types de turbines de détente. Les procédés de l'invention s'avèrent particulièrement utiles pour la récupération de puissance à partir de flux de vapeur superchauffée très haute pression dans un procédé de production d'oléfines. Lesdits flux sont en général produits par craquage thermique de matières premières dérivées du pétrole appropriées, et les oléfines produites et purifiées sont en général de l'éthylène et/ou du propylène.
