Description

Harbor for loading and unloading the cargo and carbon dioxide}

The present invention relates to a port facility capable of handling conventional cargo and unloading carbon dioxide, and more particularly, to a port capable of interlocking cargo unloading and carbon dioxide unloading.

Carbon dioxide, released in large quantities due to increased use of fossil fuels, is designated as one of the Greenhouse Gases (GHGs) that cause global warming. Carbon dioxide is classified as a very important greenhouse gas because its global warming index is lower than other greenhouse gases, but it accounts for approximately 80% of the total greenhouse gas emissions and also regulates emissions. Therefore, various international agreements regulate countries to reduce greenhouse gas emissions. One of the technologies derived from this is the amount of carbon dioxide released into the atmosphere by recovering carbon dioxide from various industrial sites and storing it in a separate place. CO2 treatment technology has been introduced to reduce the pressure.

Treatment steps to reduce carbon dioxide emissions are largely carried out through four stages: carbon dioxide recovery, separation, concentration, transport and storage.

Exhaust gas containing carbon dioxide generated in the industrial field is recovered and separated and concentrated to concentrate only carbon dioxide. This separation and concentration technique of carbon dioxide is performed through an absorption process, an adsorption process, or a membrane separation process.

On the other hand, the triple point of carbon dioxide is known as -56.3 ℃, 0.517MPa, and the carbon dioxide separated and concentrated by the above process is mainly transported in the liquefied state by cooling and compression. At this time, the liquefaction of carbon dioxide can be achieved by dedicating various known means such as expansion method, multistage cooling method, mixed cooling method widely used for liquefaction of natural gas.

The transport of liquefied carbon dioxide is known to be more economical than using a pipe when the transport distance is more than 1000 km. Therefore, in the transportation of carbon dioxide between countries, a ship is appropriate as a means of transporting carbon dioxide, and a ship for transporting carbon dioxide should have a tank facility capable of maintaining a liquefied state of carbon dioxide cooled at high pressure and low temperature.

Existing ships capable of carrying pressurized, low temperature liquefied gas include compressed natural gas (PLNG) transport ships (ExxonMobil, US2005 / 037245). A transport tank for transporting natural gas in a liquefied state of approximately 1.7 MPa, -115 ° C is presented.

In addition, there are LPG carriers that transport pressurized LPG (Pressurezied LPG) by technology in a similar field. One of the widely used LPG carriers is equipped with a low-temperature, high-pressure pressure tank, similar to the conditions of a carbon dioxide transport tank transported in a liquefied state of approximately 0.6MPa, -50 ℃.

Such a combined vessel is to install a high pressure low temperature tank in which carbon dioxide is stored in some of the cargo hold, the other cargo hold is used to load general cargo such as containers.

In order to store liquefied carbon dioxide in ships, a port with a terminal for unloading carbon dioxide should be constructed, or a marine loading arm should be installed on the coast where carbon dioxide transport vessels can be accessed.

In addition, it has the purpose of providing a countermeasure against vapor gas (BOG) for stable carbon dioxide storage. It also has the purpose of enabling the pressure control of the carbon dioxide transport tank in the vessel generated during unloading.

In addition, it has the purpose of matching the tank pressure, temperature conditions of the vessel that carries carbon dioxide for the first time after drying in accordance with the operating conditions in advance.

In addition, it has the purpose of preventing freezing due to pressure drop in a sufficient pipe during the following reverse process.

Referring back to FIG. 3, the carbon dioxide unloading system 1 may further include a reliquefaction facility 13 for converting gaseous carbon dioxide into liquid carbon dioxide.

The storage tank 11 has a condition that a large amount of steam gas (BOG) is generated by exchanging carbon dioxide with a plurality of ships anchored in the port from time to time. Therefore, the reliquefaction facility 13 is provided to collect and re-liquefy the vapor gas generated in the storage tank (BOG) to stabilize the storage storage lead storage tank in the storage tank.

In addition, the transfer tank 220 of the anchored vessel also after the voyage to the dock when the internal pressure of the transfer tank is increased to the maximum, the reliquefaction equipment provided in the carbon dioxide unloading system (1) provided in the port ( 13) it is necessary to adjust the pressure of the transfer tank.

Of course, if the vessel is equipped with its own reliquefaction equipment, the steam gas can be self-liquefied itself during the operation of the ship, but the combined vessel is difficult to provide a reliquefaction facility mainly for economic reasons. The combined use of the reliquefaction facility in the port can greatly help the stability of the transfer tank.

The reliquefaction facility 13 has a withdrawal pipe 132 for compressing the vapor gas (BOG) generated in the storage tank 11 through the first compressor 131 and then transferring it to the reliquefaction apparatus 133, and The second pump 134 for pressurizing the liquefied carbon dioxide through the liquefaction apparatus 133, the carbon dioxide pressurized through the second pump 134 passes, the re-injection is inserted into the inner bottom of the storage tank (11) Tubing 135 is included.

The withdrawal pipe 132 is normally connected to the upper portion of the storage tank so as to discharge the gaseous carbon dioxide that is concentrated in the upper portion of the storage tank like the gas pipe. At this time, the outlet pipe 132 is provided with a first compressor 131 having a known configuration, and pressurizes the collected vapor gas and supplies it to the reliquefaction apparatus 133.

The reinjection pipe 135 allows the liquefied carbon dioxide to flow back into the storage tank 11, and the second pump 134 provided in the reinjection pipe 135 has a known configuration as the first pump.

The vapor gas generated from the storage tank 11 is processed through the reliquefaction facility 13 having such a configuration, the storage tank 11 is a transport tank of the ship through the gas piping 114, the gas pipeline 111 Since it is in communication with the liquefaction equipment, it is possible to lower the pressure of the transfer tank under high pressure due to steam gas.

That is, the high pressure state due to the vapor gas of the transfer tank 220 is lower pressure than the transfer tank 220, and is connected to the storage tank 11 having a larger storage volume of gaseous carbon dioxide than the transfer tank 220, It is possible to lower the pressure primarily, and furthermore, by operating the reliquefaction facility 13 in the case where the inside of the transfer tank 220 and the storage tank 11 are equally high, The pressure can be lowered more reliably secondarily.

On the other hand, Figure 4 is a block diagram schematically showing a reliquefaction equipment according to another embodiment.

It is coupled to the storage tank 11 to discharge the vapor gas of the storage tank, the single pipe 136 may be provided with an on-off valve 137.

In the reliquefaction apparatus 13 ′ according to another embodiment, the vapor gas withdrawn from the transfer tank 220 is locked directly to the reliquefaction apparatus 133 by locking the on / off valve 137 without passing through the storage tank 11. Inflow.

As a result, it is possible to relieve the high pressure of some transfer tanks having an appropriate operating pressure lower than that of the storage tank. On the other hand, regardless of the operating conditions of the storage tank and the transfer tank is directly connected to the transfer tank and the reliquefaction facility will be able to quickly reduce the pressure of the transfer tank.

On the other hand, Figure 5 is a block diagram schematically showing the regasification equipment of the carbon dioxide loading system employed in the port capable of loading and unloading the carbon dioxide shown in FIG.

The carbon dioxide unloading system 1 vaporizes the stored liquid carbon dioxide so that freezing does not occur due to the pressure drop in the storage tank 11 or the transfer tank 220 to generate gaseous carbon dioxide, and then transfers the storage tank 11 or the connected transfer. Regasification facility 14 to be injected into the tank 220 may be further provided.

In addition, the regasification facility 14 is a vessel that stores carbon dioxide for the first time after drying or transport tank repair, or the carbon dioxide in which the liquid carbon dioxide can be injected into the transfer tank 220 which is at atmospheric pressure (mainly atmospheric pressure) without being used for a long time. It is also used to change to a high pressure environment above the triple point.

Specifically, the regasification facility 14 has a vaporizer 142 for vaporizing the liquid carbon dioxide drawn out through the third pump 141 provided in the storage tank 11, and a gas-liquid separator 143 connected to the vaporizer. And, the gaseous carbon dioxide separated from the gas-liquid separator includes a transfer pipe 144 is in communication with the gas pipe 114.

Vaporized carbon dioxide contains saturated liquid carbon dioxide. Therefore, the vaporized carbon dioxide passes through the gas-liquid separator 143 to classify pure gaseous carbon dioxide and liquid carbon dioxide, and the gaseous carbon dioxide obtained through the gas-liquid separator 143 is configured to be introduced into the gas pipe 114 through the transfer pipe. The liquid carbon dioxide is returned to the storage tank 11 through the liquid inlet pipe 116.

On the other hand, in order to more actively inject the gas carbon dioxide obtained through the regasification facility 14 into the transport tank of the vessel, the second compressor 145 for pressurizing the gas carbon dioxide through the transport pipe 144 is the gas pipe ( 114 may be connected in parallel.

The second compressor 145 pressurizes gaseous carbon dioxide and has a known configuration like the first compressor. The pressurized carbon dioxide is injected into the transfer tank 220 through the gas pipe 114 and the gas pipeline 111 to increase the pressure of the vessel.

In addition, by cooling the gaseous carbon dioxide through the above-described temperature control means it is possible to match the transfer tank to the operating conditions.

On the other hand, when it is not necessary to operate the second compressor according to the operating conditions of the transfer tank, the on-off valves provided at the front and rear ends of the second compressor are closed, and the on-off valves installed in parallel to the original gas pipe are opened to open the second compressor. Gas carbon dioxide can be injected directly into the transfer tank without going through it.
