Title (EN) REDUCING CORROSION IN A TURBOMACHINE
(FR) RÉDUCTION DE LA CORROSION DANS UNE TURBOMACHINE
Abstract: front page image
(EN)A method and system for reducing corrosion in a turbomachine. The method may include providing a process gas to a condenser, wherein the process gas contains a condensate having a pH level that is acidic. The condenser may be configured to remove at least a portion of the condensate from the process gas. Any condensate that is not removed is a remaining condensate. The method may further include increasing the pH level of the remaining condensate to above about 4 by mixing the process gas and the remaining condensate with an amount of pH modifier to form a mixture, and directing the mixture to a compressor coupled to the condenser, wherein the compressor is configured to compress the mixture.
(FR)La présente invention concerne un procédé et un système pour réduire la corrosion dans une turbomachine. Le procédé peut comprendre l'envoi d'un gaz de transformation vers un condenseur, le gaz de transformation contenant un condensat présentant un niveau de pH acide. Le condenseur peut être configuré pour retirer au moins une partie du condensat du gaz de transformation. Tout condensat non retiré est un condensat restant. Le procédé peut en outre impliquer d'augmenter le niveau de pH du condensat restant à plus de 4 environ en mélangeant le gaz de transformation et le condensat restant avec une certaine quantité de modificateur de pH pour former un mélange, et de diriger ce mélange vers le condenseur. Dans ce procédé, le compresseur est configuré pour comprimer le mélange.
