Definitions
- the present invention relates to the field of devices capable of carrying out thermal transfer.
- the characteristic of an HIDiC column is that heat is transferred from a hot enrichment zone to a cooler depletion zone.
- the enrichment zone is set at a pressure greater than the depletion zone.
- the pressure jump to be achieved is small, which minimizes the recompression costs.
- the pressure jump necessary for the economical implementation of an HIDiC column requires that the energy cost of this recompression be lower than that of the energy consumption of a conventional distillation column, said consumption of which is measured at reboiler level thereof.
- the invention achieves this goal thanks to a thermal transfer process between a first and a second fluid in which the first and the second fluid circulate respectively on either side of a thermally conductive wall of a one-piece assembly formed in a single piece arranged inside a device, the one-piece assembly comprising:
- the first three-dimensional honeycomb structure and the second three-dimensional honeycomb structure being located on either side of said wall and integral with said wall,
- each of the first and second fluids is in particular both in a liquid phase and in a gas phase, the liquid phase of the first fluid flowing in one direction opposite to the gas phase of the first fluid and the liquid phase of the second fluid flowing in a direction opposite to the gas phase of the second fluid.
- each of the first and second fluids is in particular both in the liquid phase and in the gas phase, the liquid phase of the first fluid flowing against the current of the gas phase of the first fluid and the liquid phase of the second fluid flowing against the current of the gas phase of the second fluid.
- the speed of the gas phase of each of the first and second fluids is between 0.5 m / s and 5 m / s, preferably between 1 m / s and 3 m / s.
- the first fluid corresponds in particular to a first counter-current flow and the second fluid to a second counter-current flow. More particularly, the first fluid corresponds in particular to a first flow in two-phase gas-liquid countercurrent form and the second fluid to a second flow in two-phase gas-liquid form against the current.
- a material transfer is carried out simultaneously with the thermal transfer.
- a transfer of material in each of the three-dimensional structures is carried out simultaneously with the thermal transfer.
- the method according to the invention is remarkable in that the heat transfer and the transfer of material take place simultaneously within the device.
- each of the two fluids is both in the liquid phase and in the gas phase. Liquid trickles over the solid surface while gas occupies the rest of the structure.
- the structure In order to ensure optimal contact between the two phases, the structure must be fully wetted and at the same time the gas must circulate throughout the structure, without taking a preferential path. This is made possible by the three-dimensional honeycomb architecture of each of the structures, which has a large interface area and which therefore makes it possible to create a large contact surface between the two phases.
- the one-piece unit in one piece makes heat transfer more efficient.
- energy is diffused inside each of the structures thus greatly limiting heat transfer through the wall.
- the monobloc assembly is in one piece according to the invention, there is a continuity of material between the three-dimensional honeycomb structures and the thermally conductive wall, thus allowing heat transfer through said wall.
- a further subject of the invention is a device capable of carrying out a heat transfer between a first and a second fluid circulating respectively on either side of a thermally conductive wall, said device being configured to implement the method described above, the device comprising a monobloc assembly formed in a single piece comprising:
- the first three-dimensional honeycomb structure and the second three-dimensional honeycomb structure being located on either side of said wall and integral with said wall,
- the one-piece assembly guarantees good thermal performance. In the case of use in a distillation column, it also guarantees good separation performance.
- one-piece assembly is meant an assembly formed in one piece, the first three-dimensional honeycomb structure and the second three-dimensional honeycomb structure both being inseparable from the wall.
- the device can be a heat exchanger or a separation column, in particular a distillation column, an absorption column, or a stripper.
- the device can be a heat exchanger.
- the device is suitable for carrying out a transfer of material simultaneously with the thermal transfer.
- the device then improves heat exchange while maintaining material transfer performance.
- Material transfer performance is particularly necessary for the implementation of separation processes in many industries for the transformation of various chemical, energy, food and biotechnological materials.
- material transfer performance is therefore meant the separation of material, which is the very purpose of a distillation column, an absorption column, or a stripper.
- the device can be a separation column, in particular a distillation column, an absorption column, or a stripper, or two reactive separation columns, one producing heat and the other consuming.
- a separation column in particular a distillation column, an absorption column, or a stripper, or two reactive separation columns, one producing heat and the other consuming.
- Such a device makes it possible to very significantly improve the performance of the distillation, absorption or stripping processes, which are separation processes within which it is important to simultaneously manage the material and heat transfer processes. These processes play an important role in the oil, gas, petrochemical and chemical industries, and in particular in installations intended for the treatment of natural gas, for deacidification for example, or combustion gas, for decarbonation for example, for which the control of energy consumption must be minimized.
- the device is a distillation column or a heat exchanger, in particular a distillation column.
- the device is a distillation column comprising a heat exchanger configured to exchange heat between two two-phase fluids, in particular each containing a liquid phase and a gas phase.
- the distillation column comprises one or more monobloc assemblies according to the invention configured so that the length of the distillation column is equal to a target length.
- One-piece assemblies can be screwed and / or glued to each other.
- the device can be an HIDiC distillation column.
- the HIDiC distillation column comprises in particular an enrichment zone and a depletion zone, in which the first fluid and the second fluid circulate respectively.
- the wall of the one-piece assembly notably separates the enrichment zone from the impoverishment zone.
- the device improves the heat exchange between the enrichment zone and the depletion zone while maintaining the performance of material transfer in each of said zones.
- the device may be a concentric HIDiC distillation column.
- the concentric HIDiC column according to the invention exhibits a high energy gain, in particular for the separation of compounds with close volatility.
- concentrate HIDiC distillation column is meant an HIDiC distillation column comprising an enrichment column and a concentric depletion column.
- the enrichment zone is an enrichment column and the depletion zone is a depletion column, the enrichment column and the depletion column being concentric.
- the enrichment column comprises in particular the first three-dimensional thermally conductive honeycomb structure.
- the depletion column comprises in particular the second thermally conductive three-dimensional honeycomb structure.
- the temperature difference between the top and the bottom of the distillation column may be less than or equal to 20 ° C. The lower the temperature difference between the top and the bottom of the distillation column, the greater the energy gain.
- the device is configured so that each of the first and second fluids are both in liquid phase and in gas phase, the liquid phase of the first fluid flowing in a direction opposite to the gas phase of the first fluid and the liquid phase of the second fluid flowing in a direction opposite to the gas phase of the second fluid.
- a countercurrent gas / liquid flow can be observed on each side of the wall.
- the device is configured so that the speed of the gas phase of each of the first and second fluids is between 0.5 m / s and 5 m / s, preferably between 1 m / s and 3 m / s.
