Abstract

Se proporcionan métodos y sistemas para controlar la infiltración de aire ambiental dentro y la exfiltración de un gas de proceso fuera de un sistema Rankine orgánico. Un primer mecanismo de sellado, por ejemplo, un sello de gas seco doble se puede usar para evitar la exfiltración del gas del proceso cuando el sistema Rankine orgánico está en operación. Un segundo mecanismo de sellado, por ejemplo, un sello de anillo estático inflable se puede usar para evitar la infiltración de aire ambiental cuando el sistema Rankine orgánico está en el modo inactivo. Uno o más sensores de presión pueden ser provistos en el sistema Rankine orgánico para determinar si ha ocurrido la infiltración de aire ambiental y que el sistema necesita una purga.
