Abstract
Un sistema de sello mecánico de gas seco configurado para inhibir emisión de gas de proceso. El sistema de sello mecánico que tiene primeros sellos de primera y segunda etapa tándem, y un subsistema de suministro de gas de separación individual configurado para dirigir un suministro de gas de separación desde una entrada a través de porciones de interconexión del sello de primera etapa dentro de una cavidad de proceso y desde la entrada a través de las porciones de interconexión del sello de segunda etapa y hacia afuera a través de una salida a la atmósfera, inhibiendo con ello la emisión de gas de proceso entre un alojamiento de compresor y un árbol de compresor giratorio.
