Abstract

The invention refers to an arrangement for the recovery of heat which can be used in plants for the synthesis of dissolved hydrochloric acid and which at the same time produces steam. Such plants generally comprise a furnace, a heat exchanger, a cooled absorber and an after-runnings column. The invention concerns an arrangement having means for bringing together the amounts of heat of the cooling fluids from the heat-exchanger and the absorber, whereby the production of steam is possible.

Description

La présente invention est relative à un dispositif de récupération de Ca- lories adaptable aux unités de synthèse d'acide chlorhydrique en solution permettant la génération de vapeur d'eau. The present invention relates to a device for recovering calories adaptable to hydrochloric acid synthesis units in solution allowing the generation of water vapor.

Une unité de synthèse d'acide chlorhydrique en solution comprend en général les éléments suivants
- un four dans lequel le chlore et l'hydrogène brûlent pour donner du gaz chlorhydrique, ce four étant refroidi par de l'eau,
- un échangeur de chaleur permettant le refroidissement du gaz chlorhydrique,
- un absorbeur dans lequel le gaz chlorhydrique est absorbé par de l'eau, cet absorbeur étant refroidi par de l'eau,
- une colonne de queue dans laquelle passent les gaz non absorbés.A hydrochloric acid synthesis unit in solution generally comprises the following elements
- an oven in which chlorine and hydrogen burn to give hydrochloric gas, this oven being cooled by water,
- a heat exchanger allowing the cooling of the hydrochloric gas,
an absorber in which the hydrochloric gas is absorbed by water, this absorber being cooled by water,
- a tail column through which the nonabsorbed gases pass.

Tous ces éléments sont souvent constitués essentiellement de graphite. All these elements are often essentially made of graphite.

La disposition de ces éléments les uns par rapport aux autres peut varier d'une unité de synthèse a l'autre. The arrangement of these elements with respect to each other can vary from one synthesis unit to another.

Pour pouvoir générer de la vapeur, il faut travailler avec un fluide caloporteur à une température supérieure a 1000 C. To be able to generate steam, it is necessary to work with a heat transfer fluid at a temperature higher than 1000 C.

Or, dans la zone d'absorption, le film acide est au maximum à 100-1100 C sous pression atmosphérique. However, in the absorption zone, the acid film is at a maximum at 100-1100 C under atmospheric pressure.

Cette zone ne permet donc pas de produire de la vapeur. Toutefois, l'eau de refroidissement de cette zone s'est réchauffée et l'on peut envisager de récupérer les calories qu'elle a prises. This zone therefore does not allow the production of steam. However, the cooling water in this area has warmed up and we can consider recovering the calories it has taken in.

Dans la zone échangeur de chaleur, la température du gaz chlorhydrique est par contre beaucoup plus élevée, et de ce fait le fluide caloporteur peut être a une température nettement supérieure à 1000 C. On the other hand, in the heat exchanger zone, the temperature of the hydrochloric gas is much higher, and therefore the heat transfer fluid can be at a temperature clearly above 1000 C.

Selon l'invention, on récupère les calories des zones échangeur et absorbeur qui, grâce a un dispositif convenable, sont suffisantes pour générer de la vapeur d'eau. According to the invention, the calories are recovered from the exchanger and absorber zones which, by virtue of a suitable device, are sufficient to generate water vapor.

Un tel dispositif est essentiellement caractérisé en ce qu'il comporte des moyens combinant les calories prises par les fluides de refroidissement de l'échangeur et de l'absorbeur, ces fluides étant de l'eau. Such a device is essentially characterized in that it comprises means combining the calories taken up by the cooling fluids of the exchanger and of the absorber, these fluids being water.

Selon l'invention, on peut envisager plusieurs dispositifs. Trois d'entre eux sont illustrés par les figures 1, 2 et 3 dans lesquelles, on retrouve les éléments classiques d'une unité de synthèse d'acide chlorhydrique à savoir
- un four 1, avec son circuit de refroidissement,
- un échangeur 2,
- un absorbeur 3, avec son circuit de refroidissemnt,
- une colonne de queue 4.According to the invention, several devices can be envisaged. Three of them are illustrated by FIGS. 1, 2 and 3 in which we find the classic elements of a hydrochloric acid synthesis unit, namely
- an oven 1, with its cooling circuit,
- an exchanger 2,
- an absorber 3, with its cooling circuit,
- a tail column 4.

La disposition de ces éléments les uns par rapport aux autres étant représentée de manière éclaêe pLur plus de clartL mais ne correspondant pas obligatoirem.ent leur líspOsiti sn réelle. The arrangement of these elements with respect to each other being shown in an illuminated manner for greater clarity, but not necessarily corresponding to their real reality.

Selon le dispositif représenté figure 1, l'eau de refroidissement de l'echangeur 2 tourne en circuit ferme. Ce circuit présente une boucle dans laquelle sont placés un rebouil,eur 5 (par exemple un rebouilleur type Kettle) et une pompe 6. L'eau se réchauffe au niveau de la zone échangeur, passe dans le rebouilleur et est recyclée par la pompe. According to the device shown in Figure 1, the cooling water of the exchanger 2 rotates in a closed circuit. This circuit has a loop in which are placed a reboiler, eur 5 (for example a reboiler type Kettle) and a pump 6. The water heats up at the level of the exchanger zone, passes through the reboiler and is recycled by the pump.

Selon son débit, tout ou partie de l'eau de refroidissement sortant de l'absorbeur 3, donc réchauffée est envoyée dans le rebouilleur eau elle se vaporise. Depending on its flow rate, all or part of the cooling water leaving the absorber 3, therefore heated, is sent to the reboiler water it vaporizes.

Des dispositifs de sécurité et de contrôle sont installés sur les circuits des fluides
- un vase d'expansion 7,
- deux indicateurs régulateurs, un de température 8 sur le circuit de re froidissenent de l'absorbeur et un de niveau 9 placé dans le rebouilleur 5,
- un indicateur régulateur de pression 10 sur le circuit de la vapeur.Safety and control devices are installed on the fluid circuits
- an expansion tank 7,
- two regulating indicators, one of temperature 8 on the cooling circuit of the absorber and one of level 9 placed in the reboiler 5,
- a pressure regulator indicator 10 on the steam circuit.

A titre d'exemple, les niveaux thermiques peuvent etre les suivants
Zone échangeur 2
température de l'eau entrant : 1500 C sous une pression supérieure ou égale à 5 bars,
température de l'eau sortant : 1600 C,
température de paroi i 2100 C.For example, the thermal levels can be as follows
Exchanger zone 2
incoming water temperature: 1500 C under a pressure greater than or equal to 5 bars,
leaving water temperature: 1600 C,
wall temperature i 2100 C.

Zone absorbeur 3
température du gaz chlorhydrique pénétrant dans l'absorbeur : 2000 C,
température de l'eau entrant : 300 C,
température de l'eau sortant : 800 C.Absorber zone 3
temperature of the hydrochloric gas entering the absorber: 2000 ° C.,
incoming water temperature: 300 C,
leaving water temperature: 800 C.

Rebouilleur 5
température de la vapeur : 1340 C,
pression de la vapeur : 3,5 bars absolus.Reboiler 5
steam temperature: 1340 C,
steam pressure: 3.5 bar absolute.

On arrive ainsi à récupérer 60 % de la chaleur totale de la combustion et de l'absorption. We thus manage to recover 60% of the total heat of combustion and absorption.

Ainsi, pour une unité de synthèse produisant 41,2 tonnes par jour d'acide chlorhydrique à 100 , on peut produire 1,8 tonne par heure de vapeur d'eau à 3,5 bars absolus. Thus, for a synthesis unit producing 41.2 tonnes per day of 100 hydrochloric acid, it is possible to produce 1.8 tonnes per hour of steam at 3.5 bar absolute.

De ces résultats, on voit immédiatement l'intérêt d'un tel dispositif. From these results, we can immediately see the advantage of such a device.

Selon le dispositif representé figure 2, le circuit de refroidissement de l'échangeur comprend un pot flash 1 et une pompe 6. Selon son débit, tout ou partie de l'eau de refroidissement sortant de l'absorbeur, donc réchauffée est amenée à la base du pot flash 1 : il se produit alors une détente directe de l'eau chaude venant de l'etwhallgeur 2 générant de la vapeur.  According to the device shown in FIG. 2, the cooling circuit of the exchanger comprises a flash pot 1 and a pump 6. Depending on its flow rate, all or part of the cooling water leaving the absorber, therefore heated, is brought to the base of the flash pot 1: there is then a direct expansion of the hot water coming from the whallheater 2 generating steam.

Selon le dispositif représenté figure 3, on intègre un rebouilleur au niveau de la zone échangeur de chaleur 2 - ce qui évite l'emploi d'une pompe -, et selon son débit tout ou partie de l'eau de refroidissement sortant de l'absorbeur 3 donc réchauffée est amenée directement dans l'échangeur 2 qui possède une botte de vapeur. Dans ce cas, pour éviter d'avoir une zone de blocs échangeur en vapeur sèche, il est nécessaire que four et échangeur soient horizontaux. According to the device represented in FIG. 3, a reboiler is integrated at the level of the heat exchanger zone 2 - which avoids the use of a pump -, and according to its flow all or part of the cooling water leaving the absorber 3 therefore heated is brought directly into the exchanger 2 which has a steam bundle. In this case, to avoid having an area of dry steam exchanger blocks, it is necessary that the oven and exchanger are horizontal.

Les trois dispositifs ont en commun l'avantage de très peu modifier la conception des unités de synthèse existantes. The three devices have in common the advantage of modifying very little the design of the existing synthesis units.

Les deux premiers peuvent en particulier très bien s'adapter à des unités de synthèse dites intégrées dans lesquelles
échangeur/absorbeur ne forment qu'une unité,
l'ensemble four - échangeur/absorbeur est placé verticalement dans une calandre unique.The first two can in particular adapt very well to so-called integrated synthesis units in which
exchanger / absorber form only one unit,
the oven - exchanger / absorber assembly is placed vertically in a single grille.

Il suffit alors de dissocier les fonctions échangeur/absorbeur comme représenté figure 4. It then suffices to dissociate the exchanger / absorber functions as shown in FIG. 4.

Le premier dispositif présente l'avantage supplémentaire d'avoir un circuit intermédiaire independant, en boucle fermée. En cas de fuite, il n'y a pas de pollution du circuit vapeur par de l'acide chlorhydrique. The first device has the additional advantage of having an independent intermediate circuit, in a closed loop. In the event of a leak, there is no pollution of the steam circuit with hydrochloric acid.

Le troisième dispositif présente lui l'avantage d'être plus compact et donne l'installation la moins chère. De plus, il n'y a pas de pompe. Cependant il oblige à placer les éléments four-échangeur en position horizontale.  The third device has the advantage of being more compact and gives the cheapest installation. In addition, there is no pump. However, it requires placing the furnace-exchanger elements in a horizontal position.
