Abstract

DC60 (09/04/56) The distillation apparatus according to the present invention includes a purification tower, a separation tower located above the purification tower, a sump unit located at a predetermined stage of the separation tower and arranged to retain the fluid flowing downward, a heat exchanger located in the sump unit, a second pipe for introducing the vapor in the purification tower to the separation tower heat exchanger, and a third pipe for introducing the fluid flowing out of the separation tower heat exchanger to the purification tower. Further, a wider path with a lower pressure than the pressure in the purification tower is connected to the downstream side of the third pipe. The distillation apparatus can divert a first flow toward the inside of the purification tower through the third pipe to a second flow branching from the third pipe toward the pipe on the reduced pressure side. This arrangement of the apparatus can achieve further energy savings and a reduction in production costs. The distillation apparatus according to the present invention includes a purification tower, a separation tower located above the purification tower, a sump unit located at a predetermined stage. The separation tower is pre-configured and structured to retain the fluid flowing downstream. A heat exchanger is housed in the sump unit, a second pipe is for introducing the steam in the purification tower into the separation tower heat exchanger, and a third pipe is for introducing the fluid flowing out of the separation tower heat exchanger into the next purification tower. A wider path with a lower pressure than the pressure in the purification tower is connected to the downstream side of the third pipe. The distillation unit can divert the first flow toward the inside of the purification bundle through the third pipe to the second flow at the branch gate from the third pipe to the pipe on the reduced pressure side. This structure arrangement can achieve further energy saving results and reduction in production costs.
