Emulsification Method of Fuel Oil and Desulfurizer for Sulfur Oxide Reduction

The present invention relates to a method for emulsifying fuel oil and a desulfurization agent for reducing sulfur oxides, and more particularly, by mixing a desulfurization agent with fuel oil such as bunker C oil to emulsify it, sulfur oxide (SO _x ) emission is reduced during fuel combustion It relates to an emulsification method of fuel oil and desulfurization agent for reducing sulfur oxides.

_{Sulfur oxides (SO x} ) and nitrogen oxides (NO _x ) have been pointed out as pollutants that cause air pollution. In particular, sulfur oxides are contained in industrial flue gas emitted from the combustion of fossil fuels containing sulfur, thereby reducing acid rain. It shows problems such as causing various environmental pollution such as

A desulfurization method for removing sulfur oxides from these industrial flue gases has been continuously studied, and a flue gas desulfurization method, which is a general post-combustion treatment method, has been used in factories or power plants using fossil fuels.

The flue gas desulfurization method refers to desulfurizing the flue gas after burning fossil fuel containing sulfur gas, and this flue gas desulfurization method can be divided into a wet method and a dry method. The wet method is a method to remove sulfur oxides by washing the flue gas with ammonia water, sodium hydroxide solution, lime milk, etc., and the dry method removes sulfur oxides by adsorbing or reacting sulfur dioxide by contacting particles or powders such as activated carbon or carbonate with the flue gas. way to do it

In particular, the sulfur oxide content of fuel oil such as heavy oil (MGO, MDO, DDO) such as bunker C oil used in marine engines is 1,000 to 3,000 times higher than that of automobile fuel. It contains 130 times more sulfur oxides than automobiles, so it is called High Sulfur Fuel Oil (HSFO) and is known as the main culprit of environmental pollution.

For this purpose, conventionally, flue gas desulfurization is performed as a post-treatment using a wet desulfurization system for ships to remove sulfur oxides emitted from marine engines. In general, the wet desulfurization system uses a pump to pass washing water (NaOH) through a cooler. It is a method in which sulfur oxides are removed by post-treatment by supplying to a scrubber, and contacting the exhaust gas with washing water in the scrubber.

At this time, in order to maintain the sulfur oxide removal ability of the wet desulfurization system at a certain level, the pH of the washing water is monitored to automatically control the supply amount of the washing water. After sludge is generated, the sludge is collected and stored in a sludge tank, and post-treatment desulfurization is operated in a manner that is treated after anchoring.

As described above, the conventional post-treatment wet desulfurization technology requires a lot of manpower and cost due to the complicated water purification process of washing water, and it is necessary to separately construct a separate complex desulfurization facility. There was a problem that it was not practically easy in terms of space and cost.

Therefore, in order to dramatically improve the environmental pollution problems caused by the combustion of marine fuel oil and the emission of sulfur oxides, the method is simple and easy to apply, and research on an effective desulfurization method that can significantly reduce the emission of sulfur oxides is urgently needed. the current situation.

When the amount of the desulfurization agent is supplied in less than 3 parts by weight, the amount of the desulfurization agent dispersed in the fuel oil is small, so the desulfurization effect is reduced. When the amount of the desulfurization agent is supplied in excess of 10 parts by weight, the combustion efficiency of the emulsion state of the fuel oil and the desulfurization agent is reduced. have.

As the desulfurization agent, a liquid catalyst for removing _{sulfur oxides (SO x} ) generated during combustion of fuel oil may be used.

It has a 2:1 structure where it enters and bonds, and the octahedral layer is characterized by a dioctahedral structure in which only 2 of the 3 cation sites in the bonding structure are filled with cations.

The desulfurization agent acts as a chelating agent while the above-described oxide and liquid composition are mixed and reacted to form a chelated metal chelate compound through coordination with the metal.

In addition, the liquid composition can be removed by adsorbing on ash generated when the combustion product is burned and reacting with sulfur oxides present in the ash. _{NaBO 2 is induced from Na 2} B ₄ O ₇ , which is sodium tetraborate, and through hydrogenation NaBH ₄ is generated, and the generated NaBH ₄ meets oxygen and sulfur oxide and reacts with sodium sulfate (Na ₂ SO ₄ ) to remove sulfur oxide, and the reaction process is shown in Schemes 1 and 2 below.

The adsorption effect of sulfur oxides may be activated when the desulfurization agent is mixed with combustion products in a temperature range of 400 to 1200 ° C., but combustion in a temperature range of 600 to 900 ° C. may exhibit high efficiency.

Step (b) is a step (S120) of forming droplets of the mixture formed in step (a).

In this step, emulsification is performed by dispersing the desulfurization agent in the fuel oil by forming droplets to emulsify the fuel oil and desulfurization agent present in the mixture to W/O.

A method of forming the droplets of the mixture in this step may use various known methods, but preferably a homogenizer may be used.

In addition, as a method of forming droplets of the mixture in this step, the droplets may be formed by passing a droplet atomization unit in a transfer pipe for transporting the mixture.

The droplet atomization unit means a unit that forms droplets by applying pressure or shear force to the mixture, and as an embodiment of the droplet atomization unit, prepare a plate formed with the same diameter as the inner diameter of the tube in the transfer pipe for transporting the mixture of step (a) and fixed, and a plurality of holes of fine diameter are formed in the plate.

The mixture in the conveying tube is conveyed by the conveying pump, and the mixture is pressed against the droplet atomization unit. The mixture impeded in movement by the droplet atomization unit is finely dispersed as it exits the fine holes formed in the droplet atomization unit by shear force and pressure to form droplets of the mixture.

The hole diameter of the droplet atomization unit used as an embodiment of this step may be 1 to 500 micrometers (㎛). For example, the hole diameter of the droplet atomization unit may be 1 to 400 micrometers, 1 to 300 micrometers, 1 to 200 micrometers, 1 to 100 micrometers, 1 to 50 micrometers, 50 to 500 micrometers, 100 to 500 micrometers. micrometers, 200-500 micrometers, 300-500 micrometers, 400-500 micrometers, 50-400 micrometers, 100-300 micrometers, or 200-300 micrometers. In the case of a diameter of less than 1 micrometer, there is a problem in that the flow of the entire process is slowed down because the amount of the mixture in which droplets are formed through the droplet atomization device is small, and when a diameter of more than 500 micrometers is used, the effect of droplet formation is reduced. There is a problem with falling.

In addition, in this step, the gas may be further supplied and mixed.

In this step, the gas supplied during the droplet formation of the mixture forms an air bubble in the mixture, and the repeated occurrence and breakage of air bubbles impacts the surface tension of fuel oil and desulfurization agent to facilitate droplet formation. have.

In this step, the gas may be supplied before, during, or after the mixture passes through the droplet atomization unit, or may be configured to be supplied interlockingly or independently to each process.

As the gas supplied in this step, various known gases can be used, but the gas supplied in the present invention helps emulsify fuel oil and desulfurization agent, and air or oxygen (O) ₂ ) can be used.

The gas can form bubbles of 1 to 500 micrometers (μm) in the fuel oil. For example, the size of the bubble is 1 to 400 micrometers, 1 to 300 micrometers, 1 to 200 micrometers, 1 to 100 micrometers, 1 to 50 micrometers, 50 to 500 micrometers, 100 to 500 micrometers. , 200 to 500 micrometers, 300 to 500 micrometers, 400 to 500 micrometers, 50 to 400 micrometers, 100 to 300 micrometers, or 200 to 300 micrometers. When a bubble with a size of less than 1 micrometer is formed, air bubbles are not well formed inside the mixture, and when a bubble with a size of more than 500 micrometers is formed, the stability of the bubble is deteriorated and it is easily destroyed and escapes to the outside can be

Step (c) is a magnetization step (S130) of magnetizing the mixture in which droplets are formed in step (b) by passing it through a magnetic field.

This step is a step of magnetizing the mixture passing through the pipe by configuring the mixture to pass the magnetic field by forming a magnetic field by placing a permanent magnet on the outside of the pipe line through which the droplet-formed mixture moves in step (b).

Since fuel oil has hydrophobicity and desulfurization agent has hydrophilicity, the mixture that has passed through a magnetic field creates an electric charge or a magnetic moment by magnetic force, maximizing the dispersion effect as an emulsion.

The magnetic field used in this step is between 9,000 and 15,000 gauss. For example, the magnetic field may be 9,000 to 13,000 gauss, 9,000 to 11,000 gauss, 9,000 to 10,000 gauss, 10,000 to 15,000 gauss, or 12,000 to 15,000 gauss. In a magnetic field outside this range, the formation of electric charges or magnetic moments in the mixture does not occur or occurs weakly, and the dispersion effect is reduced.

In addition, the magnetic field in this step can use a variety of known methods that can form a magnetic field, such as a magnet or an electromagnet, but preferably it can be formed by using a permanent magnet, and one or more permanent magnets are installed in a piping line can be

The magnetic field may be configured to flow in the same direction as the conveying flow of the mixture, or may be configured to form a magnetic field in a direction perpendicular to the conveying flow.

Step (d) is a swirl mixing step (S140) of swirling mixing the magnetized mixture of step (c).

In this step, the fuel oil and the desulfurization agent are strongly dispersed and mixed by pushing the magnetized mixture in step (c) with a pump to rotate it.

In this step, the mixture can be mixed by rotating it by putting it into a container having a circular or oval shape so that it can be mixed by rotation.

In addition, the vortex mixing allows the fuel oil and desulfurization agent to be better dispersed in the mixture by introducing it into a vortex mixer composed of multi-stage cylinders of different sizes and rotating it.

3 is a perspective view showing an embodiment of the swirl mixer 200 used in this step. Referring to FIG. 3 , the swirl mixer 200 is formed of an outer cylinder 210 and an inner cylinder 220 . An inlet 212 through which the mixture is put is formed at one side of the outer cylinder 210 , and an outlet 222 through which the mixture is ejected by a hole penetrating through the center is formed in the inner cylinder 220 .

When the direction in which the inlet 212 is formed is the upper surface of the inner cylinder 220, the upper surface of the inner cylinder 220 is formed in the same position as the upper surface of the outer cylinder 210, and the lower surface is spaced apart from each other. .

More detailed description of the swirl mixing method in this step, the mixture magnetized in step (c) is introduced into the swirl mixer inlet 212 under the static pressure of the pump (FIG. 3 arrow A), and the mixture Silver is strongly mixed while performing dynamic rotation with a strong rotational force in the space formed between the outer side of the inner cylinder 220 and the inner side of the outer cylinder 210 .

The mixture rotated several times by pressure is discharged to the outside riding the outlet 222 formed on the lower surface of the inner cylinder 220 (arrow B in FIG. 3).

In the present invention, after step (d) is completed, a gas separation step of separating the gas contained in the mixture in which the desulfurization agent and fuel oil are mixed may be further included.

As an embodiment of the gas separation step, the mixture of step (d) is filled and pressurized in a pressurizable chamber, and may be separated into a gas and a liquid of fuel oil and desulfurization agent present in the mixture by pressurization.

The separated liquid (mixture) performs the collision step (S150) of step (e) to be described later.

Step (e) is a collision step (S150) in which the mixture discharged in step (d) collides.

In this step, the mixture discharged to the outlet 222 of the swirling mixer 100 of step (d) is ejected by an ejector such as a spray, and it strongly collides with a structure such as a wall or pipe to form finer droplets. to be.

In step (d), the swirl mixed mixture is made to collide with a colliding structure such as a wall or pipe to form finer droplets in the mixture, so that it is well dispersed and the emulsified state can be maintained for a long time.

When the mixture is collided in this step, various known structures such as walls or pipes can be used as the collided structure, and the collide can be collided at various angles, but it can collide at an angle of 15° in the direction of the ejected flow. have.

The emulsification method of the present invention can be carried out once or repeatedly several times according to the method of the present invention.
