Abstract
A heat integrated distillation column including a cylindrical shell having an upper and a lower end and at least one first inner volume and at least one second inner volume in the shell, and being in heat exchanging contact with each other through a wall separating the volumes. The heat integrated distillation column having the capacity to exchange heat through the wall from the first volume into the second volume, whereby the inside of the heat exchanging means is in open connection with the first volume.
Claims19
A heat integrated distillation column comprising:
- an outer shell with an upper and a lower end;
- a first inner volume within the outer shell;
- a second inner volume within the outer shell, the first and the second inner volumes being separated by a dividing wall and being in heat exchanging contact with one another through the dividing wall;
- a heat exchanger fluidly connected to one of either the first or the second inner volumes to further exchange heat between the first and second inner volumes
- a plurality of trays with downcomers positioned within either one of the first inner volume, the second inner volume, or both the first and second inner volume;
- and
- wherein the heat exchanger is positioned at the downcomer of one of the plurality of trays.
A heat integrated distillation column comprising:
- an outer shell with an upper and a lower end;
- a first inner volume within the outer shell;
- a second inner volume within the outer shell, the first and the second inner volumes being separated by a dividing wall and being in heat exchanging contact with one another through the dividing wall;
- a heat exchanger fluidly connected to one of either the first or the second inner volumes to further exchange heat between the first and the second inner volumes;
- a plurality of trays with downcomers positioned within either one of the first inner volume, the second inner volume, or both the first and second inner volume;
- and
- wherein the heat exchanger is positioned between the plurality of trays.
A method for distillation, the method comprising:
- providing a heat integration distillation column having an outer shell with a first and a second volume in heat exchanging contact with one another through a dividing wall;
- providing at least one heat exchanger to further exchange heat between the first and second volumes wherein the heat exchanger is fluidly connected with one of the first or the second volumes;
- providing a plurality of trays with downcomers positioned within the first inner volume, the second inner volume, or both the first inner and the second inner volume wherein the heat exchanger is positioned either at the downcomer of one of the plurality of trays or between the plurality of trays;
- and
- moving contents through the heat exchanger to facilitate further heat transfer from a fluidly connected first or second volume to the other volume without transferring mass between the first volume and the second volume.
