1. A system, comprising:
a vapor absorption machine, comprising:
a hot water generator comprising an interior having a fluid disposed therein; and
a chiller comprising an interior having a fluid disposed therein; and
a gas oil separation plant (GOSP), comprising:
a compressor comprising an outlet;
a reheater comprising:
a first inlet in fluid communication with the outlet of the compressor;
a first outlet configured to remove a gas from the GOSP;
a second inlet; and
a second outlet;
a fin fan cooler comprising:
an inlet in fluid communication with the second outlet of the reheater; and
an outlet;
a separator comprising:
an inlet in fluid communication with the outlet of the fin fan cooler;
a first outlet in fluid communication with the second inlet of the reheater; and
a second outlet configured to remove a condensate from the GOSP;
wherein:
the vapor absorption machine is configured to decrease a temperature of the fluid in the interior of the chiller using heat from the fluid in the interior of the hot water generator;
a portion of the fluid in the interior of the hot water generator is in thermal communication with a portion of a fluid disposed between the outlet of the compressor and the first inlet of the reheater; the system is configured so that a temperature of the fluid in the interior of the hot water generator is increased using heat from the fluid in between the outlet of the compressor and the first inlet of the reheater; and
a portion of the fluid in the interior of the chiller is in thermal communication with a portion of a fluid disposed between the outlet of the fin fan cooler and the inlet of the separator; and the system is configured so that the fluid in the interior of the chiller reduces a temperature of the fluid between the outlet of the fin fan cooler and the inlet of the separator.
