Definitions
- the present invention relates to a method for removing a dispersed phase from an emulsion.
- An emulsion is a mixture of at least two immiscible liquid phases, at least a first phase being dispersed in the second phase, generally in the form of droplets.
- the first phase forms a so-called dispersed or discontinuous phase and the second phase forms a so-called continuous phase.
- Each phase can obviously be a liquid phase of a product or a mixture of products.
- the term emulsion will be taken in a broad sense without focusing on the dispersion characteristics such as the size of the droplets, etc.
- Emulsions can form and be present in a desired manner or not on many occasions:
- hydrocarbon phases with an aqueous phase, in particular to extract a component at least partially miscible with the latter, for example hydrocarbons or alcohols, in particular methanol.
- the washing can then cause the formation of a water emulsion in the hydrocarbon phase or vice versa.
- the emulsion formed is then desired but only temporarily and it may be necessary to deplete the dispersed phase to obtain a purified continuous phase and / or to recover the dispersed phase.
- separation processes include, among others, distillation, decantation, solid adsorbent bed adsorption, extraction, stripping, etc. processes.
- a separation process relies on a difference in one or more physico-chemical properties between the compounds to be separated and exploits this difference to cause separation. It may for example be differences in boiling temperatures, relative densities, affinities with a material, sizes, shapes, masses, etc ... The greater the difference in property, the greater the separation will be easy and selective.
- the separation processes can be associated with each other, usually successively, and / or repeated with different operating conditions in order to obtain the desired separation (s). It will then mainly be a question of treating complex mixtures and / or whose constituents have a difference in physicochemical properties that is not very marked or insufficient, so that it is necessary to use several separation processes involving several physical properties. different chemicals. This may also be necessary in purification processes aimed at a high degree of purity of the product. In the case of immiscible products, and in particular emulsions, several processes can be employed:
- the settling methods do not make it possible to deplete the product present in a phase in dissolved form when the immiscibility of said products is not total. It is therefore generally extremely difficult to obtain high purity with a settling process alone and in particular to fall below the saturation threshold of the compound to be depleted in the phase to be preserved.
- Another solution may be to resort to a distillation of the emulsion.
- This solution is not suitable for all products.
- the distillation can be limited by azeotropic formation phenomena.
- a third separation technique that can be used is the adsorption onto solid adsorbent support beds such as molecular sieves, silica gels, and the like. These types of adsorbents are generally not suitable in the case of mixtures of liquid droplets and heavy hydrocarbons. In addition, the regeneration of these adsorbents requires a high temperature, which is very energy-intensive.
- the stripping process is a separation process in which a liquid flow is brought into contact with a gas flow so as to cause a transfer of selective material between said liquid flow and the gas flow, and this according to the relative affinities of the different products between the two gaseous and liquid phases, the affinity of a constituent for the gaseous or liquid phase based mainly on its volatility under the operating conditions and on the thermodynamic equilibrium conditions of the constituents in the vapor and liquid phases.
- Stripping processes are high-separation methods of interest because of their relative simplicity and because they can be implemented under relatively simple and energy-saving conditions.
- gas stripping should be understood within the scope of the present invention as designating only this first variant, namely a stripping of the liquid phase by the gas phase.
- gas stripping must be understood as signifying strictly stripping by the gas, it is to say that the gas is the stripping means for removing the constituent to be removed from the liquid phase.
- the stripping technique is frequently used to deplete VOC (volatile organic components) and dissolved gases from a stream of water in order to clean it up.
- VOC volatile organic components
- the transfer takes place from the liquid phase and the VOCs are carried away by the gas phase. It is therefore a gas stripping process within the meaning of the present invention.
- the principle of a gas stripping process is therefore to promote the transfer of the component to be depleted from the phase Iiqu ide to the gas phase. To do this, the constituent to be eliminated must diffuse in the continuous phase towards a liquid / gas interface, cross it and volatilize there.
- the transfer of material takes place according to a phenomenon of diffusion and desorption of the volatile compound at this interface and caused by the flow of gas. It is based on the thermodynamic equilibrium to be reached by the volatile compound between the two phases. Because of its greater relative volatility, the compound to be removed has a natural tendency to be present in a gaseous phase until its saturation vapor pressure under the temperature conditions under consideration. As the gas stream ensures the constant renewal of the gas phase, this saturating vapor pressure can not be reached by the volatile compound, which therefore desorbs from the phase I1 in a continuous manner, which causes its gradual elimination of the liquid phase. The desorption and gradual removal of the volatile compound is governed by the diffusion of said volatile compound in the liquid phase.
- volatilization of the constituent should not be confused with its boiling, in which case no liquid / gas interface would be crossed and there would be no phenomenon of desorption of the constituent. This would then be substantially equivalent to distillation.
- the gas stripping processes are mainly aimed at the el imination of constituents issus and are carried out under conditions promoting both the diffusion of said constituent to the liquid / gas interface and the volatil ization of this constituent at the level of this interface.
- the gas stripping processes are thus favored by relatively high temperatures (nevertheless remaining below the boiling point) and a reduced pressure.
- US Pat. No. 5,256,258 aims to eliminate water and other volatile compounds that may be present in a heat transfer fluid. To do this, the coolant is subjected to a flow of nitrogen circulating against the current and which causes the volatile compounds. It should be noted that the coolant is at a temperature between 150 ° C and 400 ° C. It follows that the water and the compounds to be depleted are not present in the fluid in liquid form forming a distinct phase, but already in gaseous dissolved form. Thus this document describes a gas stripping process after boiling and passage in the dissolved phase of the components to be driven. US 5 259 931 purifies water containing dissolved hydrocarbons by stripping in air.
- stripping can even be used sometimes improperly.
- the document WO 201 1/059843 aims to dehydrate an oily phase by suction generating a stripping air flow. To do this, however, the oily phase is heated to a temperature above the boiling point of the water. It follows that the water is no longer in liquid form in the oily phase and no longer forms an emulsion. This process does not have any effects on a process previously described, and is similar to a desilteration under controlled atmosphere and reduced pressure and has the same disadvantages.
- the document EP 1 586 620 describes a process for purifying a drilling crude oil comprising a step of washing an emulsified liquid fraction before a step of stripping said liquid fraction in which a gas is injected in countercurrent. It should be noted, however, that this gas is mainly used to acidify the emulsion. It is therefore a transfer of material from the gas phase to the liquid phase, which does not constitute gas stripping within the meaning of the present invention. Note also that it is necessary to use a final decanter to separate the phases of the emulsion.
- Document US 5 240 61 7 also specifically relates to the phase separation of an emulsion, and more particularly to an emulsion of water and oil, by injecting air bubbles into the emulsion, the operation taking place at a temperature below the boiling point of the water. It should be noted that the description of this document lacks details and does not clearly identify which phase of the emulsion is driven by the air bubbles.
- the driven element is water
- the method described therefore applies mainly to an oil-in-water emulsion.
- the continuous phase being by nature much larger in terms of volume, its elimination requires a much longer time if one wishes to recover the maximum of continuous phase or recover the dispersed phase.
- the present invention relates to a method for removing a dispersed phase from an emulsion, characterized in that it comprises a step of subjecting said emulsion to gas stripping carried out under conditions of temperature and pressure lower than the liquid boiling conditions of the disperse phase liquid, and wherein the composition of said gas is selected so that the dispersed phase has a volatility and an affinity with this gas greater than that of the continuous phase of said emulsion.
- the gas / liquid interface is naturally between the gaseous phase and the continuous phase of the emulsion and not between the gaseous phase and the liquid phase. to "striper".
- the dispersed phase is by definition not dissolved in the continuous phase and is not subject to diffusion towards the interface where it can be volatilized. As a result, stripping is difficult to apply to an emulsion.
- the injected gas makes it possible to overcome mechanically the impossibility of diffusion through the continuous phase. It is thus possible in particular to cause a direct contact between the droplets of volatile compound and the gas.
- the stripping technique also enables the constituent of the dispersed phase existing in dissolved form to be entrained in the continuous phase.
- the process thus makes it possible to obtain a purity of the conti nue which is extremely high, and in particular with a residual concentration of dispersed phase component which is much lower than the degree of saturation of the continuous phase by said constituent.
- a residual water concentration as low as 1 ppm.
- the gas stripping process is carried out in the presence of means for contacting the gas phase with the dispersed liquid phase.
- Such means make it possible to increase the contact surface between the gas phase and the dispersed liquid phase.
- the stripping process is carried out in the presence of breaking means of the emulsion.
- the breaking of the emulsion firstly makes it possible to promote contact with the gaseous phase, but also to promote the passage of the constituent (s) from the dispersed liquid phase to an issoute form in the continuous phase. In its dissolved form, the component (s) are then subjected to the usual stripping process.
- the means for bringing into contact and / or breaking the emulsion comprise means for the turbulent flow of the gas.
- the gas stripping method is carried out with an emulsion in flow.
- the process can then be carried out continuously.
- the flow of the emulsion during the stripping step is at least partially turbulent.
- the emulsion and the stripping gas flow countercurrently.
- the emulsion and the stripping gas may flow cocurrently.
- the emulsion is injected through spraying means.
- the emulsion passes through at least one lining.
- Such packing helps to increase the contact surfaces between the different phases by generating local flow turbulence. In addition, it can help break the emulsion.
- the packing is a structured packing.
- Such packings may make it possible to obtain a particularly important specific surface area.
- the lining is a son / fiber or thin film lining.
- the son / fiber or thin film packings allow better breaking of the emulsion.
- the thin film packing has a film thickness characteristic of less than 0.25 mm.
- the emulsion passes through several packings, the first packing being the thin film packing.
- the stripping gas has a temperature close to but less than the boiling point of the emulsion under the pressure conditions of the stripping.
- the temperature of the emulsion is close but lower than its boiling point under the pressure conditions of the stripping.
- the stripping step is carried out at ambient temperature.
- the stripping step is performed under pressure conditions substantially equal to atmospheric pressure.
- the continuous phase of the emulsion is a hydrocarbon phase.
- the dispersed phase is an aqueous phase.
- the aqueous phase comprises methanol or other alcohols, especially aliphatic alcohols.
- the process according to the invention is followed by a step of at least partial condensation of the constituent (s) of the dispersed phase entrained (s) by the stripping gas.
- the emulsion is a condensate obtained from a previous separation step.
- the composition of the stripping gas used comprises one or more secondary components present in the continuous phase and different from the constituent of the phase which is persried to be elimed.
- Such a model may be particularly useful when it is desired to increase the selectivity of the process and the emulsion comprises several volatile compounds capable of being indiscriminately carried by the gaseous phase.
- methanol or even other alcohols especially aliphatic such as methanol, ethanol, propanol, butanol and pentanol, etc.
- a light condensate comprising, for example, propane or butane that we do not particularly want to eliminate.
- the stripping gas can then be enriched as soon as it is injected into propane or butane.
- the amount of these compounds present in the stripping gas will limit their extraction from the continuous phase of the emulsion and their entrainment by the gas phase.
- the secondary compounds are present in the stripping gas used in a proportion close to their saturation in the gaseous phase.
- the stripping gas is already saturated, it can not lead to more of these compounds.
- the method comprises at least one stripping gas recirculation step for adjusting its composition to secondary components of the continuous phase.
- the recirculation loop advantageously comprises a step of separating the constituents entrained by the gas: the constituents of the discontinuous phase of the emulsion being extracted from the circuit and eliminated, the constituents of the continuous phase that one wishes to preserve being reinjected in the stripping gas so the maintain saturation in these secondary compounds or directly recycled in the treated liquid phase.
- the separation may include a light cooling step to recondense a portion of the volatile products.

- This step can be carried out in several ways, in particular by refrigeration, forcing the condensation of these hydrocarbons.
