Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a gasification system for remediation of soils contaminated with high-concentration crude oil,

The present invention relates to a gasification system for purifying contaminated soil, and more particularly, to a gasification system for gasifying a soil contaminated with crude oil at a high concentration to facilitate the recovery of the purified soil.

Due to the massive scale of oil industry, oil spill accidents are continuously occurring in a variety of places ranging from industrial complexes such as oil well development sites, refineries, transport facilities, moving vehicles, storage facilities, gas stations,

Soil contaminated with oil, particularly soil contaminated with crude oil such as heavy oil, has a problem that the contamination persists semi-permanently unless it is purified through a separate process even over time.

Soil contamination caused by the leakage of crude oil over heavy oil is relatively longer than that of light oil such as persistent pollution, and the fluidity of the pollutant is low and the range of contamination diffusion is relatively small. Because of this, pollutants are concentrated at a high concentration around the pollution source. Therefore, it is not easy to reduce contaminants by artificial soil remediation or restoration treatment, as opposed to contamination by oil of relatively low hydrocarbon system such as light oil, and according to some experts opinion, It is reported that there is no method.

For example, soil contaminants generated by crude oil spillage at refineries in domestic refineries have had to deal with waste at high cost due to lack of proper treatment methods. In particular, the large-scale contaminated soils in the oil-producing Middle East region are exposed and weathered under a desert climate for a long time, and are characterized by solid appearance like coal. Also, they contain very high viscosity crude oil, Belt can be seen as oil. It is known that the viscosity of crude oil contained in contaminated soil is above 10,000 cPs with little fluidity, remains within 30 cm of the topsoil due to low permeability by soil depth, and contains at least several tens% of oil in soil.

In the Middle Eastern countries, there is concern about ecological effects due to oil pollution accumulated so far. However, it is very difficult to properly treat the soil with the physico-chemical treatment method or the biological treatment method, which is a purification technology of conventional oil contaminated soil It is true.

Until now, soil washing or thermal desorption has been known to be one of the most promising techniques for recovering soil contaminated with crude oil.

Soil washing method is a method of injecting a detergent such as steam or surfactant into the soil and inducing it to come into contact with the contaminant, thereby causing the contaminant to be desorbed from the soil particles. It is a technique of extracting / separating contaminants from the soil using a separate facility And is widely commercialized. However, this method is not recommended as an effective restoration method because the efficiency of cleaning is low due to the formation of tar balls when the contaminants are high in concentration and the chemical desorption efficiency from the soil particles is low.

On the other hand, the thermal desorption technique is a technique of applying heat to the contaminated soil to induce improvement of the viscosity of the contaminant to desorb the crude oil from the soil particles, or to induce combustion reaction and discharge it to the vapor phase. However, thermal desorption technology is not economical because it requires separate fuel to raise the temperature to a high temperature where direct and indirect thermal desorption is possible, and most of the harmful dioxins, VOCs, SOx, NOx and CO 2 And the like are generated, leading to the movement of the contaminated phase.

Therefore, there is a need to develop a method, apparatus, or system for purifying soil contaminated with high viscosity and high concentration of crude oil.

The present invention aims to provide a gasification system capable of purifying and restoring soil contaminated with high viscosity and high concentration of crude oil.

In order to solve the above-described problems, the present invention provides a pretreatment unit for crude oil contaminated soil; A gasification unit in which the crude oil contaminated soil pretreated by the pretreatment unit flows and is gasified; A gasification reaction chamber for gasifying the crude oil contained in the contaminated soil; and a gasification reaction chamber for gasifying the crude oil contained in the contaminated soil; And a gasifier located at a lower portion of the gasification reaction chamber and containing a soil storage tank for transporting and storing the soil after the gasification reaction. The present invention also provides a gasification system for purifying crude oil contaminated soil.

According to an embodiment of the present invention, it is preferable that a rock hopper is provided under the soil storage tank so that the soil can be discharged to the outside when a certain amount of soil is collected.

The present inventors have been intensively studying a method for purifying high-viscosity and high-concentration crude oil contaminated soil such as 'Tartite' in the Middle East, which has been recognized as a waste for a long time. However, when the gasification process is used, The present invention has been completed based on the fact that high-concentration crude oil can be easily removed.

The gasification process converts energy sources such as coal, petroleum residues and woody cellulose into industrially useful syngas (mainly hydrogen and carbon monoxide) to generate electricity, as raw materials in various petrochemical fields such as ammonia and methane. The present invention makes this technique available for the purification of soil contaminated with high viscosity, high concentration crude oil.

Hereinafter, the present invention will be described in detail with reference to the drawings and embodiments. In describing the present invention, a detailed description of related processes or configurations will be omitted so as not to obscure the gist of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a simplified illustration of a gasification system for the purification of contaminated soils according to a first embodiment of the present invention; According to this, the gasification system for purifying crude oil contaminated soil comprises a pretreatment section P1 of crude oil contaminated soil; A gasification unit P2 in which the crude oil contaminated soil pretreated in the pretreatment unit P1 flows and is gasified; And a gasification unit P3 including a gasification chamber 30 into which a synthesis gas produced by the gasification unit P2 is introduced and which gasification unit P2 is connected to a source of crude oil A gasification reaction chamber 21 for gasification; And a soil storage tank (22) located below the gasification reaction chamber (21) and in which the soil after the gasification reaction is transferred and stored.

According to one embodiment of the present invention, the oil contaminated soil is weathered in a long time contaminated state, the relatively light oil is volatilized, and most of the heavy oils remain, and the hardening proceeds considerably, and the total petroleum hydrocarbons TPH) concentration (ASTM D7066) of 400,000 ~ 600,000 mg / kg. The crude oil contained in these contaminated soils has a viscosity of 10,000 cPs or less which has almost no fluidity, and has a low permeability by soil depth and remains within 30 cm of the topsoil. The content of oil in the soil is at least several tens%, for example, By weight or more of the crude oil. Therefore, the gasification reaction can be performed without using any separate raw materials such as petroleum or coal for the gasification reaction. As a result, the crude oil can be removed and the purified soil can be obtained.

As described above, the crude oil contaminated soil according to an embodiment of the present invention is in a state where there is little fluidity of high viscosity, and therefore it is necessary to perform pretreatment so that the gasification reaction can be performed within a short time. The pretreatment can be performed in such a manner that the contaminated soil of crude oil can be homogenized to have consistent physical properties as a raw material for gasification by methods such as grinding, grinding, heating and solvent extraction. In the present invention, the contaminated soil of crude oil is slurried using a solvent extraction method. 1, the soil 11 contaminated with crude oil is slurried in the agitator 12 and then supplied to the hopper 13 so as to be transported to the gasification unit P2, . At this time, the slurry-contaminated crude oil contaminated soil can be preheated and pressurized to increase the gasification reaction efficiency before being input into the gasification unit P2 from the hopper 13.

The contaminated soil contaminated with crude oil through the pretreatment is transferred to the gasification unit (P2). The gasification part (P2) purifies the contaminated soil through the gasification reaction in the gasifier (20) and produces a syngas. The gasifier 20 includes a gasification reaction chamber 21 and a soil storage tank 22 located below the gasification reaction chamber 21. The gasifier 20 is provided with an air inlet 23 and a steam inlet 25 at the upper end thereof so as to cause a gasification reaction in the gasification reaction chamber 21. Contaminated soils contain high concentrations of crude oil and are used as raw materials for gasification by themselves. When the homogenized crude oil contaminated soil is put into the gasification reaction part of the gasifier, it reacts with the injected air and steam to produce the soil from which the syngas and contaminants are removed. In order to minimize environmental pollution, it is more preferable to inject oxygen so as to allow pure oxygen combustion through the air inlet. Particularly, in order to prevent the generation of atmospheric pollution gas such as NO x , SO x , It is preferable to inject oxygen.

The purified soil and the syngas produced by the gasification reaction in the gasification reaction chamber 21 are sent to the soil storage tank 22 located below the gasification reaction chamber 21. In the soil storage tank 22, separation of the purified soil and syngas takes place due to the properties of solid and gas, and the separated syngas flows to one side of the gasifier 20, more specifically to the upper end of the soil storage tank 22 And is conveyed through the syngas discharge port 27 formed on one side to the boiler P3. In addition to cooling the syngas at a high temperature, it can block the reaction of the residual mixed gas with the atmosphere, thereby facilitating the monitoring of the synthesis gas generation and reducing the capacity of the heat exchanger in the post treatment.

The soil in which the syngas is separated and purified is temporarily stored in the soil storage tank 22. When the predetermined amount is collected, the soil is periodically discharged to the outside through the lock hopper 24 provided at the lower end of the soil storage tank 22 . According to one embodiment of the present invention, the soil discharged from the soil storage tank 22 is restored to not exceed 5,000 mg / kg of total petroleum hydrocarbon (TPH) concentration (ASTM D7066). The discharged soil 26 according to the present embodiment separates and discharges the syngas produced after the gasification reaction with the pretreatment P3 so that only the solid soil remains after the synthesis gas is separated, There is an advantage that the further treatment, for example, the treatment such as solid-liquid separation or drying, is not required.

The syngas transferred to the pumping unit P3 is cooled in the water purifier 30 by the water supplied to the water inlet 31 and cooled. The synthesis gas is supplied to the post-treatment unit (not shown) through the synthesis gas discharge port 32, Lt; / RTI > In the post-treatment section, the synthesis gas can be heat-exchanged in the heat exchanger for discharge, and after purification and separation processes for removing toxic gases such as H 2 S, CO 2 and HCN contained in the synthesis gas, . Alternatively, the synthesis gas may also be converted to a desired useful synthesis gas in a reactor provided for producing industrially useful gas in a post-treatment section.

The steam generated by heat exchange with the synthesis gas in the heat exchanger may be supplied to the gasification reactor 20 through the steam inlet 25 again.

The post-treatment process of the synthesis gas in the post-treatment section may be carried out according to a process ordinarily practiced in this field, unless otherwise specified.

2 is a simplified illustration of a gasification system for purifying crude contaminated soil according to a second embodiment of the present invention. According to the second embodiment of the present invention, there is an advantage that an existing gasifier can be used.

2, the pretreatment unit P21 slurries the soil 101 contaminated with crude oil in the agitator 102, as described in the first embodiment of the present invention, and then the slurry is transported to the gasification unit P2 The hopper 103 is opened. At this time, the slurry-contaminated crude oil contaminated soil can be preheated and pressurized to increase the gasification reaction efficiency before being introduced into the gasification unit P22 from the hopper 103.

The stirrer may be equipped with heating equipment to allow the oil contaminated soil to be heated to facilitate fluidization of the contaminated soil.

The crude contaminated soil homogenized through the pretreatment is transferred to the gasification unit P22. The gasification unit P22 purifies the contaminated soil through a gasification reaction in the gasifier 200 and produces a syngas. The gasifier 200 includes a gasification reaction chamber 201 and a gasification reaction chamber 201. The gasification reaction chamber 201 includes a gasification chamber 202 in which a synthesis gas and a soil are transferred and cooled by cooling water. The gasifier 200 is provided with an air inlet 203 and a steam inlet 205 at an upper end thereof so as to cause a gasification reaction in the gasification reaction chamber 201. Contaminated soils contain high concentrations of crude oil and are used as raw materials for gasification by themselves. When the homogenized crude oil contaminated soil is put into the gasification reaction chamber of the gasifier, it reacts with the injected air and steam to produce the soil from which the syngas and contaminants are removed. In order to minimize environmental pollution, it is more preferable to inject oxygen so as to allow pure oxygen combustion through the air inlet. Particularly, in order to prevent the generation of atmospheric pollution gas such as NO x , SO x , It is preferable to inject oxygen.

The purified soil and the syngas produced by the gasification reaction in the gasification reaction chamber 201 are sent to the " crushing chamber " 202 located below the gasification reaction chamber 201.

The syngas transferred to the kneading chamber 202 is cooled by the cooling water supplied to the water inlet 206, cooled, and then transferred to the post-treatment unit (not shown) through the syngas outlet 207. In the post-treatment section, the synthesis gas can be heat-exchanged in the heat exchanger for discharge, and after purification and separation processes for removing toxic gases such as H 2 S, CO 2 and HCN contained in the synthesis gas, . Alternatively, the synthesis gas may also be converted to a desired useful synthesis gas in a reactor provided for producing industrially useful gas in a post-treatment section.

The purified soil cleaned by the cooling water in the polishing chamber 202 is discharged to the purified soil treatment unit P23 through the lock hopper 204 provided at the lower end of the gasifier if a predetermined amount is collected. The soil containing water together with the syngas in the crushing chamber 202 separates water from the purified soil treatment chamber 300 of the purified soil treatment section P23 and discharges the water to the water discharge port 302, And the soil is discharged to the soil discharge port (301). According to one embodiment of the present invention, the final restored soil is restored to a state of not exceeding 5,000 mg / kg of total petroleum hydrocarbon (TPH) concentration (ASTM D7066).
