Abstract: Un método y sistema para recuperar aceite se utiliza en un sistema de ciclo Rankie orgánico (ORC) para recuperar aceite de un evaporador del sistema de ORC y regresar el aceite a un colector de aceite. El sistema de ORC incluye un evaporador, una turbina, un condensador y una bomba, y está configurada para circular un refrigerante a través del sistema ORC. El sistema de recuperación de aceite incluye una línea de recuperación configurada para remover una mezcla de aceite y refrigerante del evaporador. La mezcla de aceite y refrigerante pasa a través de un intercambiador de calor con el fin de vaporizar refrigerante líquido en la mezcla y producir una mezcla de aceite y refrigerante vaporizado. Una línea de suministro está configurada para suministrar la mezcla de aceite y refrigerante vaporizado a la turbina, en cuyo punto el aceite puede separarse del refrigerante vaporizado y reciclarse de regreso al colector de aceite.

Abstract: A power generation system includes a non-azeotropic working fluid mixture and a Rankine cycle system. The Rankine cycle system includes a turbine generator that is driven by vapor of thefirst working fluid mixture, and a condenser that exchanges thermal energy between the vapor received from the turbine generator and a cooling medium. The working fluid mixture is characterized by a condenser temperature glide during phase change between approximately five degrees and thirty degrees Kelvin, a condensing pressure between approximately one tenth of one percent and eleven percent of a critical pressure of the working fluid mixture, and a condenser bubble point temperature between approximately one degree and nine degrees Kelvin greater than a temperature at which the cooling medium is received by the condenser.

Abstract: A cascaded Organic Rankine Cycle (ORC) system includes a bottoming cycle working fluid is first evaporated and then superheated and a topping cycle working5 fluid is first desuperheated and then condensed such that a percentage of total heat transfer from the topping cycle fluid that occurs during a saturated condensation is equal to or less than a percentage of total heat transfer to the bottoming cycle fluid that occurs during a saturated evaporation.10FIGURE 1
