Title (EN) HEAT INTEGRATION FOR HOT SOLVENT STRIPPING LOOP IN AN ACID GAS REMOVAL PROCESS
(FR) INTÉGRATION THERMIQUE POUR BOUCLE DE RECTIFICATION DE SOLVANT CHAUD DANS UN PROCÉDÉ D'ÉLIMINATION DES GAZ ACIDES
Abstract:
(EN) Systems and processes utilize one or more methods of providing overhead waste process heat to increase the feed temperature of the hot solvent stripping regeneration loop in an acid gas removal process. A heated rich solvent stream can be the primary feed for the hot solvent stripping regeneration loop, and one or more slip streams can be heated and then combined with the heated rich solvent stream to form a combined rich solvent stream prior to further processing in downstream units to remove acid gas from the solvent. A first slip stream can be heated in a stripper gas heat exchanger by heat exchange with a stripped gas stream. A second slip stream can be heated in a regenerator exchanger by heat exchange with an acid gas stream. A third slip stream can be heated in a recycle gas exchanger by heat exchange with a compressed recycle gas stream.
(FR) La présente invention a pour objet des systèmes et des procédés qui utilisent un ou plusieurs procédés de fourniture de chaleur de procédé de déchets de tête pour augmenter la température d'alimentation de la boucle de régénération et de rectification du solvant chaud dans un procédé d'élimination des gaz acides. Un courant de solvant riche chauffé peut être l'alimentation principale pour la boucle de régénération et de rectification du solvant chaud, et un ou plusieurs courants d'écoulement peuvent être chauffés et ensuite combinés au courant de solvant riche chauffé pour former un courant de solvant riche combiné avant un autre traitement dans les unités en aval pour éliminer un gaz acide du solvant. Un premier courant d'écoulement peut être chauffé dans un échangeur de chaleur de gaz à rectificateur par échange thermique avec un courant de gaz rectifié. Un deuxième courant d'écoulement peut être chauffé dans un échangeur à régénérateur par échange thermique avec un courant de gaz acides. Un troisième courant d'écoulement peut être chauffé dans un échangeur de gaz de recyclage par échange thermique avec un courant de gaz de recyclage comprimé.
