1. A heat recovery system, comprising:
a vapor recompression unit connected on a first low pressure side to an overhead vapor output of a distillation unit and connected on a first high pressure side to a first heat exchanger for a condensate vessel;
a first compressor connected on a second low pressure side to an outlet of the condensate vessel and connected on a second high pressure side to a second heat exchanger for a medium pressure receiving system, wherein the first heat exchanger transfers heat from a first vapor of an organic fluid received from the distillation unit via the vapor recompression unit to a working fluid of a nonorganic fluid in the condensate vessel to generate a second vapor of the working fluid that is output via the outlet to the first compressor; and
a second compressor connected on a third low pressure side to the second high pressure side of the first compressor and connected on a third high pressure side to a third heat exchanger included in a high pressure receiving system.
