Description

Hydrogen sulfide reactor and hydrogen sulfide production method {APPARATUS AND METHOD FOR PRODUCING HYDROGEN SULFIDE}

The present invention relates to a hydrogen sulfide reactor and method for producing hydrogen sulfide by contacting liquid sulfur with hydrogen, and more particularly, to a hydrogen sulfide reactor that can maximize the hydrogen sulfide conversion rate by increasing the contact area and contact time between liquid sulfur and hydrogen, and It relates to a method for producing hydrogen sulfide.

Hydrogen sulfide is a flammable and toxic gas, and is mostly produced by hydrodesulfurization of sulfur compounds contained in petroleum and natural gas. And it is mainly acquired by the reaction of sulfur and hydrogen.

Hydrogen sulfide is an industrially important intermediate as a material for synthesizing various sulfur-containing compounds, and a raw material for manufacturing fine chemical products such as dyes, pesticides, plastics, pharmaceuticals, cosmetics, and sulfide-based all-solid-state batteries, and for generating metal sulfides. It is widely used as a starting material.

As a method for producing hydrogen sulfide from sulfur and hydrogen, a catalytic reaction and a non-catalytic reaction are known.

The catalytic reaction is a method of generating hydrogen sulfide by reacting sulfur gas and hydrogen gas in a reaction tube filled with a catalyst, and removing reaction heat by circulating a heat medium outside the reaction tube. Such a catalytic reaction is disclosed in Japanese Patent Publication No. 2010-515658.

At this time, when the concentration of sulfur is high in the catalytic reaction of hydrogen sulfide, there is a problem that a large temperature rise occurs due to the heat of reaction, and the catalyst may be abnormally heated and deteriorated. In addition, in order to increase the conversion rate to hydrogen sulfide, the reaction temperature must be increased. As such, when the reaction temperature is increased, impurities such as hydrogen polysulfide (H ₂ S _x ), which are side reaction products, also increase.

On the other hand, the non-catalytic reaction is a method of generating hydrogen sulfide by supplying hydrogen gas into liquid sulfur so that the hydrogen gas reacts with the sulfur gas generated by evaporation of liquid sulfur.

The reaction heat generated when hydrogen gas and sulfur gas react is recovered in the process of contact with liquid sulfur, so the reaction temperature does not become excessively high, but the contact area between liquid sulfur and hydrogen gas is small and the contact time is relatively short. The disadvantage is that the conversion rate to hydrogen sulfide is low.

1 is a schematic diagram of a hydrogen sulfide reactor according to the present invention, and FIG. 2 is a cross-sectional view showing the internal configuration of a reaction chamber.

The hydrogen sulfide reactor according to the present invention relates to a reactor for producing hydrogen sulfide by reacting liquid sulfur with gaseous hydrogen. The biggest feature is that it is configured to remarkably increase the hydrogen sulfide conversion rate by increasing the concentration of ultrafine particles and increasing the contact area and contact time between sulfur and hydrogen.

That is, the hydrogen sulfide reactor according to the present invention includes a reaction chamber 100 having an inner space isolated from the outside, a liquid sulfur supply pipe 200 for supplying liquid sulfur to the inner space of the reaction chamber 100, and the A heater 300 that heats the liquid sulfur stored in the inner space of the reaction chamber 100, and a liquid that collects the liquid sulfur stored in the inner space of the reaction chamber 100 and then sprays it upward into the inner space of the reaction chamber 100. A sulfur spray pipe 400 and a hydrogen supply pipe 500 for supplying hydrogen gas between a point where liquid sulfur is stored and a point where the liquid sulfur is sprayed in the inner space of the reaction chamber 100 are included as basic components. is configured to

The liquid sulfur supplied into the reaction chamber 100 through the liquid sulfur supply pipe 200 is collected at the bottom of the reaction chamber 100 as shown in FIG. 1, and after being heated by the heater 300, the liquid sulfur powder It is supplied to the military attache 400 and is sprayed into ultra-fine particles through the sulfur spray nozzle 410.

Hydrogen supplied through the hydrogen supply pipe 500 is injected into the reaction chamber 100 through the hydrogen injection nozzle 510 while liquid sulfur is sprayed into the reaction chamber 100 . The liquid sulfur particles supplied into the reaction chamber 100 are vaporized into sulfur gas and reacted with hydrogen gas in the reaction chamber 100. In this way, the reaction heat generated in the process of reacting sulfur gas and hydrogen gas is liquid Sulfur particles can be absorbed by necessary vaporization heat in the process of vaporization into sulfur gas or absorbed into liquid sulfur particles to exhibit a cooling effect, thereby preventing the temperature inside the reaction space from excessively rising. Therefore, when the hydrogen sulfide reactor according to the present invention is used, the hydrogen sulfide conversion rate can be increased compared to the method of bubbling hydrogen gas into liquid sulfur, while overheating of the reaction space can be prevented to reduce side reactions and thus high purity hydrogen sulfide can be produced. There are advantages.

At this time, when the temperature of the liquid sulfur injected into the reaction chamber 100 is lowered below a certain level, the hydrogen sulfide conversion rate decreases, and when the temperature of the liquid sulfur injected into the reaction chamber 100 is excessively increased above a certain level Impurities such as hydrogen polysulfide are increased. Therefore, the temperature of the liquid sulfur supplied to the liquid sulfur spray pipe 400 is preferably set to 300 ° C to 600 ° C, and more preferably may be 350 ° C to 500 ° C. At this time, the temperature inside the reaction chamber may be constantly maintained at 350 °C to 400 °C.

On the other hand, the hydrogen sulfide converted inside the reaction chamber 100, unreacted hydrogen gas and unreacted sulfur gas that are not converted into hydrogen sulfide are taken out through the outlet pipe 600 provided on the upper side of the reaction chamber 100 to hydrogenate After passing through the catalytic reaction column 700, it is provided to the condenser 800. Of the gases supplied to the hydrogenation catalyst reaction column 700, unreacted hydrogen gas and unreacted sulfur gas are converted into hydrogen sulfide in the hydrogenation catalyst reaction column 700, and most of the gases delivered to the condenser 800 are converted to hydrogen sulfide. It is done. In addition, the hydrogen sulfide supplied to the condenser 800 is cooled through the condensation process and then discharged to the outside through the discharge pipe 900, and the liquid sulfur generated in the hydrogen sulfide condensation process can be recovered to the reaction chamber 100 .

The outlet pipe 600, the hydrogenation catalyst reaction column 700, the condenser 800, and the discharge pipe 900 are applied in substantially the same manner to a conventional hydrogen sulfide reactor, and the outlet pipe 600 and the hydrogenation catalyst reaction A detailed description of the internal structures and functions of the column 700, the condenser 800, and the discharge pipe 900 will be omitted.

At this time, the hydrogen sulfide conversion rate increases as the contact time between the liquid sulfur spray particles and the hydrogen gas increases. Since it is drawn through, the contact time with the liquid sulfur spray particles is shortened, resulting in a lower hydrogen sulfide conversion rate.

The hydrogen sulfide reactor according to the present invention solves the above problems, that is, to maximize the contact time between the liquid sulfur spray particles and the hydrogen gas, the hydrogen injection nozzle 510 of the hydrogen supply pipe 500 is a hydrogen gas It may be configured to spray downward. When the hydrogen gas is injected downward in this way, the injected hydrogen gas descends to the point where the liquid sulfur is filled and then rises to the opposite side and is drawn out through the take-out pipe 600, so the flow path of the hydrogen gas becomes longer, and thus the sulfur spray The effect of significantly increasing the contact time with the liquid sulfur particles sprayed through the nozzle 410 can be obtained.

The hydrogen gas injected from the hydrogen injection nozzle 510 is injected at a pressure higher than a certain level. When the high-pressure hydrogen gas directly contacts the liquid sulfur stored in the lower side of the reaction chamber 100, the liquid sulfur splashes to contaminate the hydrogen injection nozzle and and the hydrogen gas does not normally flow upward, resulting in a decrease in the hydrogen sulfide conversion rate. Accordingly, a cover plate 110 covering an upper portion of the space in which the liquid sulfur is stored may be additionally provided inside the reaction chamber 100 .

In this way, when the cover plate 110 is additionally provided, the hydrogen gas sprayed downward from the hydrogen injection nozzle 510 rises after hitting the upper surface of the cover plate 110, so that the hydrogen gas directly reacts with liquid sulfur. It is possible to obtain the effect that the phenomenon of contact does not occur.

On the other hand, when the hydrogen gas supplied to the reaction chamber 100 through the hydrogen supply pipe 500 is supplied at a very low temperature, the liquid sulfur spray particles do not smoothly vaporize into sulfur gas when in contact with the hydrogen gas, resulting in a decrease in the hydrogen sulfide conversion rate. A problem may occur, and as mentioned above, if the cover plate 110 is additionally provided, there is an advantage in that the above problem can be reduced to a certain level.

That is, since the cover plate 110 installed in the reaction chamber 100 receives high-temperature liquid sulfur heat and maintains a heated state, the cover plate ( 110), it is heated to a certain level by receiving the heat, and accordingly, the effect of increasing the vaporization rate of the liquid sulfur spray particles and the hydrogen sulfide conversion rate can be obtained.

A method for producing hydrogen sulfide using the hydrogen sulfide reactor according to the present invention configured as described above will be described.

First, after supplying liquid sulfur to the inner space of the reaction chamber 100, the liquid sulfur stored in the reaction chamber 100 is heated using the heater 300. When the liquid sulfur is heated to a certain temperature or higher, the liquid sulfur transfer pump 420 compresses the heated liquid sulfur at high pressure and supplies it to the liquid sulfur spray pipe 400 to supply sulfur installed at the end of the liquid sulfur spray pipe 400. Liquid sulfur is sprayed in the size of ultra-fine particles through the spray nozzle 410.

At this time, the liquid sulfur spray particles injected into the reaction chamber 100 must be in a high temperature state so that the phenomenon of vaporization into sulfur gas can be smoothly achieved. to 600°C, more preferably from 350°C to 500°C.

In addition, as the size of the liquid sulfur spray particles sprayed into the reaction chamber 100 increases, the contact area with hydrogen gas increases and the hydrogen sulfide conversion rate improves, so the particle size of liquid sulfur sprayed into the reaction chamber 100 increases. should be 10 μm to 1000 μm, more preferably 10 μm to 500 μm.

On the other hand, since the size of the liquid sulfur spray particles sprayed through the sulfur spray nozzle 410 decreases as the liquid sulfur supplied to the liquid sulfur spray pipe 400 has a high pressure, the liquid sulfur supplied to the liquid sulfur spray pipe 400 decreases. should be compressed to 1 bar to 10 bar, more preferably to 2 bar to 5 bar. In addition, the flow rate of liquid sulfur supplied to the liquid sulfur spray pipe 400 should be 100 L / h to 10000 L / h, more preferably 500 L / h to 3000 L / h.

While the liquid sulfur spray particles are sprayed to the upper side of the inner space of the reaction chamber 100, the hydrogen gas supplied through the hydrogen supply pipe 500 is transferred to the point where liquid sulfur is stored in the inner space of the reaction chamber 100. The liquid sulfur is supplied between spraying points.

At this time, the hydrogen gas supplied into the reaction chamber 100 is preferably pure hydrogen gas, but may contain impurities of one or more of hydrogen sulfide, argon, nitrogen, carbon dioxide, methane, ethane, propane, and volatile hydrocarbons.

In addition, hydrogen supplied through the hydrogen supply pipe may have a purity of 50 vol% to 100 vol%, and more preferably 95 vol% to 100 vol% hydrogen.

The hydrogen gas injected from the hydrogen injection nozzle 510 installed at the end of the hydrogen supply pipe 500 is heated to a certain level while hitting the upper surface of the cover plate 110, and then rises to meet liquid sulfur spray particles. Some of the liquid sulfur spray particles are vaporized into sulfur gas and react with hydrogen gas to produce hydrogen sulfide.

Hereinafter, specific examples of the method for producing hydrogen sulfide according to the present invention will be described.

[Example 1]

The reaction chamber 100 was made of stainless steel with an inner diameter of 200 mm and a height of 2400 mm. Liquid sulfur was filled at the bottom of the reaction chamber 100 and heated to 400° C. by the heater 300. The liquid sulfur was finely sprayed at a flow rate of 500 L/h through the liquid sulfur spray pipe 400, and 500 L/h of hydrogen was preheated to 200° C. and continuously supplied through the hydrogen supply pipe 500 at the base. The temperature at the bottom of 10 cm of the sulfur spray nozzle 410 was kept uniformly at 383 ° C, the temperature at the top of 10 cm of the hydrogen spray nozzle 510 was 394 ° C, and the temperature at the top of 50 cm of the hydrogen spray nozzle 510 was 389 ° C. temperature was maintained uniformly

Gaseous sulfur included in the outlet of the reaction chamber 100 passed through the hydrogenation catalyst reaction column 700 and was condensed in the condenser 800 to separate from hydrogen sulfide. Liquid sulfur generated in the condenser 800 was additionally introduced to the bottom of the reaction chamber 100 to compensate for consumption of sulfur.

The gas at the outlet of the reaction chamber 100 and the gas at the outlet of the condenser 800 were analyzed. As a result, it was confirmed that hydrogen sulfide at the outlet of the reaction chamber 100 was 96.3%, hydrogen sulfide at the outlet of the condenser 800 was 99.9%, and H ₂ S ₂ was 10 ppm.

3 is a horizontal cross-sectional view of the reaction chamber 100 showing the arrangement structure of the liquid sulfur spray pipe 400.

The hydrogen sulfide reactor according to the present invention may be configured such that hydrogen gas injected from the hydrogen injection nozzle 510 can be evenly injected onto the upper surface of the cover plate 110 .

For example, when the cover plate 110 is formed in a disk shape with a circular plane shape, the hydrogen supply pipe 500 is formed in a ring shape at a portion located inside the reaction chamber 100, The hydrogen injection nozzles 510 may be arranged at equal intervals in a ring-shaped portion of the hydrogen supply pipe 500.

In this way, when the hydrogen injection nozzles 510 are arranged in a circular shape, the hydrogen gas injected from each hydrogen injection nozzle 510 is evenly distributed over the entire upper surface of the cover plate 110, so that the hydrogen gas can be heated more effectively. In addition, there is an advantage that the flow path of the hydrogen gas injected from each hydrogen injection nozzle 510 does not interfere with each other, so that the hydrogen gas can flow smoothly.

In this embodiment, only the case where the reaction chamber 100 is formed in a cylindrical shape, the cover plate 110 is formed in a disc shape, and the hydrogen injection nozzles 510 are arranged in a circular shape is shown, but the cover plate 110 The shape of and the arrangement pattern of the hydrogen injection nozzles 510 may be variously changed according to the shape of the reaction chamber 100 .

4 is a plan view of the cover plate 110 .

When the hydrogen gas injected from the hydrogen injection nozzle 510 hits the upper surface of the cover plate 110 and the hydrogen gas is directly reflected (see the dotted line arrow in FIG. 1), the contact time between the hydrogen gas and the cover plate 110 is increased. It is very short, so hydrogen gas cannot be effectively heated, and the hydrogen gas may not be evenly distributed throughout the inner space of the reaction chamber 100.

Therefore, the hydrogen sulfide reactor according to the present invention may be configured such that the hydrogen gas sprayed from the hydrogen injection nozzle 510 evenly contacts the entire upper surface of the cover plate 110 and then flows upward.

For example, when the plurality of hydrogen injection nozzles 510 are arranged in a circular shape, as shown in FIG. Radial passage grooves 112 may be formed to disperse the hydrogen gas injected from the nozzle 510 in all directions.

As such, when the radial passages are formed below the hydrogen injection nozzles 510, the hydrogen gas sprayed downward from each hydrogen injection nozzle 510 is radially dispersed along the radial passages and flows along the upper surface of the cover plate 110. then it flows upwards. In this way, when the hydrogen gas flows along the upper surface of the cover plate 110, the contact time between the hydrogen gas and the cover plate 110 is increased, and since the hydrogen gas is contacted over the entire upper surface of the cover plate 110, the hydrogen The advantage is that the gas can be heated more effectively.

In addition, when the hydrogen gas is radially dispersed along the radial passage and then flows upward, the hydrogen gas is evenly filled throughout the inner space of the reaction chamber 100, so the contact efficiency with the liquid sulfur spray particles and the resulting hydrogen sulfide The effect of remarkably improving the conversion rate may also be obtained.

At this time, the shape of the radial passage is not limited to the shape shown in this embodiment and can be changed to various shapes as long as the hydrogen gas can be radially dispersed and flowed.

5 is a schematic diagram of a hydrogen sulfide reactor according to a second embodiment of the present invention, and FIG. 6 is a schematic diagram of a hydrogen sulfide reactor of a third embodiment according to the present invention.

As shown in FIG. 5, the hydrogen sulfide reactor according to the present invention may be provided with a plurality of the sulfur spray nozzles 410. When a plurality of sulfur spray nozzles 410 are provided as described above, the sulfur spray nozzles 410 spray liquid sulfur particles not only to the center of the inner space of the reaction chamber 100 but also to the sidewall of the reaction chamber 100. Therefore, there is an advantage in that the contact rate between hydrogen gas and liquid sulfur particles can be increased.

Furthermore, in order to more effectively increase the contact rate between the hydrogen gas injected through the hydrogen spray nozzle 510 and the liquid sulfur particles, the hydrogen sulfide reactor according to the present invention, as shown in FIG. It may be arranged in two or more stages vertically.

In this way, when the sulfur spray nozzles 410 are arranged in multiple stages up and down, the hydrogen gas sprayed through the hydrogen spray nozzle 510 and rising does not come into contact with the liquid sulfur particles sprayed from the sulfur spray nozzle 410 located at the lower side. Even if it occurs, it may have an opportunity to contact the liquid sulfur particles sprayed from the sulfur spray nozzle 410 located on the upper side. That is, when the sulfur spray nozzles 410 are arranged in multiple stages up and down, the hydrogen gas sprayed through the hydrogen spray nozzles 510 and rising is given several opportunities to contact the liquid sulfur particles, thereby increasing the hydrogen sulfide conversion rate. It has the advantage of being significantly higher.

In the above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted according to the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
