Description

Catalyst loading system and method into ship}

The present invention relates to a system and method for loading catalyst onto a ship.

As the industry develops, maritime transportation using ships is expanding. In addition, with the development of industry, concerns about environmental pollution are also emerging, and many environmental regulations are being created as a response.

Ships for logistics transportation (eg, FLNG, etc.) are propelled by engines fueled by oil or gas, and in this case, exhaust gas is inevitably generated. These exhaust gases contain environmentally regulated substances such as nitrogen oxides that have a negative impact on the environment.

To protect the environment, nitrogen oxides contained in exhaust gas are divided into emission levels depending on the region. Therefore, in order to satisfy regulations according to the emission level, post-treatment technologies such as increasing engine efficiency, changing the fuel used, or reducing nitrogen oxides in exhaust gas are being proposed.

Among these, Selective Catalytic Reduction (SCR) using urea water is widely used as a post-treatment technology for exhaust gas to reduce nitrogen oxides. A catalyst made of active ingredients such as palladium (Pd), platinum (Pt), rhodium (Rd), and ruthenium (RU) is placed on the exhaust gas discharge path, and urea solution is used as a reducing agent before the exhaust gas enters the catalyst. is sprayed to cause nitrogen oxides to react in the catalyst to be reduced to nitrogen.

Therefore, it is necessary to ship a catalyst as one of the materials for post-processing exhaust gas on a ship.

Catalysts are generally supplied in drums of a certain capacity. In this case, hundreds of drums must be loaded onto the main ship and poured into a vessel one by one. During this process, many difficulties arise as there is no space to store hundreds of drums on the main ship. In addition, the time required to load hundreds of drums onto the main ship is considerable, and during this time, the main ship crane must be used only to load drums, which is a problem that affects other schedules.

Additionally, in the case of ships such as FLNG and FPSO, the process for processing gas is as follows.

It serves to collect H ₂ O (moisture) within the porous molecular sieve by passing wet feed gas through a contractor (corresponding to a vessel) filled with a molecular sieve. Mercury corrodes aluminum, the main material of the cryogenic heat exchanger in the liquefaction facility. Therefore, mercury must be removed before the liquefaction stage. The method is to flow gas through a column or vessel.

Like this, the molecular sieve that captures moisture and removes mercury is a type of catalyst and is required to be loaded into a separate vessel or storage during the gas treatment process.

According to the catalyst loading system and method on a ship according to an embodiment of the present invention, a large volume of catalyst in a drum is stored in a separate space prior to loading the catalyst on a main ship (e.g., FLNG, etc.) requiring catalyst loading. It is characterized in that the operating time of the main ship crane can be shortened by transferring the catalyst contained in the large-capacity ton bag, which is relatively small in quantity on the main ship, into the vessel where the catalyst will be accommodated.

The catalyst loading system on a ship according to this embodiment includes a primary loading system, a transport truck 80, and a secondary loading system.

In addition, the catalyst loading method using the catalyst loading system on a ship according to this embodiment involves a primary loading step (S210) in which the catalyst in a drum supplied by a catalyst supplier is transferred to a relatively large-capacity ton bag using a primary loading system. A transport step (S220) in which one or more ton bags are transported near the main ship using a transport truck 80, and a secondary loading step in which the catalyst is injected into the vessel by lifting the ton bags near the main ship using a main ship crane ( S230).

Referring to FIG. 1, the primary loading system used in the primary loading step (S210) includes a primary loading unit 120 and a crane 110 for primary loading.

Catalysts required by ships for exhaust gas purification, etc. are generally supplied in a drum 10 when provided by a supplier. The drum module 20, in which four drums 10 are mounted on one pallet, becomes the basic unit for transportation and can be transported by a forklift or the like.

The primary loading system may be established in a separate location away from the main ship.

One or more primary loading units 120 may be arranged side by side.

The primary loading unit 120 includes loading stages 121 spaced apart by a predetermined height so as to have an empty space at the bottom. A transfer hopper 122 connected to the lower space may be installed on one side of the loading stage 121. On the other side of the loading stage 121, a module mounting space may be provided where one or more drum modules 20 can be mounted.

A primary loading crane 110 is disposed on the upper part of the primary loading unit 120 to transport the drum module 20 from the floor to the loading stage 121.

The primary loading crane 110 includes a pair of first horizontal supports 111, a first girder 112 disposed across the first horizontal supports 111, and a first girder 112 along the first girder 112. It may include a first transfer unit 113 that moves back and forth.

When the plurality of primary loading units 120 are arranged in a row, the pair of first horizontal supports 111 may be arranged parallel to the direction in which the plurality of primary loading units 120 are arranged (direction A). there is.

The first girder 112 may be arranged to extend long in the B direction perpendicular to the A direction.

The first girder 112 may be implemented to be capable of reciprocating movement along the first horizontal support 111. The first horizontal support 111 is provided with a first traveling axis, so that the first girder 112 can reciprocate along the first traveling axis. The first traveling axis may be formed parallel to the A direction. In the drawing, a guide rail is formed on the side of the first horizontal support 111 to perform the function of the first traveling axis. However, this is only an example, and in some cases, the first horizontal support 111 Of course, a guide rail may be formed on the lower surface.

The first girder 112 is provided with a second traveling axis, so that the first transfer unit 113 can reciprocate along the second traveling axis. The second traveling axis may be formed parallel to the B direction. In the drawing, a guide rail is formed on the lower surface of the first girder 112 to perform the function of the second traveling axis. However, this is only an example, and in some cases, it is attached to the side of the first girder 112. Of course, a guide rail may be formed.

The first transfer unit 113 can reciprocate in the B direction along the first girder 112, and a first transfer arm 114 whose length can be varied in the vertical direction is installed below, and the first transfer arm ( A hook is attached to the end of 114).

By combining linear movement (direction A) along the horizontal support 111, the drum module 20 can be positioned at a desired position in three dimensions.

The drum module 20 on the floor can be transported to be seated on the loading stage 121 of the primary loading unit 120 by the primary loading crane 110.

When the drum module 20 is seated on the loading stage 121, the operator moves the drum 10 around the transfer hopper 122 and then lays it down, so that the catalyst in the drum 10 is transferred to the transfer hopper. Go downward through (122).

A tone bag 50 to transfer the catalyst may be placed below the transfer hopper 122. The tone bag 50 can be implemented to have a relatively large capacity compared to the drum 10. For example, the capacity of the tone bag 50 may be four times or more than that of the drum 10.

The catalyst in the drum 10 introduced into the transfer hopper 122 on the loading stage 121 may be accommodated in the tone bag 50 placed below the transfer hopper 122.

The above-described primary loading step (S210) may be individually performed in a plurality of primary loading units 120 arranged in a row. At this time, the primary loading crane 110, which transports the drum module 20 onto the loading stage 121, moves the first girder 112 in the A direction to apply catalyst to a plurality of primary loading units 120. Transfer can take place.

In addition, catalyst input into the tone bag 50 through the transfer hopper 122 from each of the plurality of primary loading units 120 arranged in a row may be performed simultaneously.

When the catalyst transfer to the ton bag 50 is completed, the ton bag 50 full of catalyst is moved to the transport step (S220) and loaded onto the transport truck 80 using the forklift 70.

The transport truck 80 is a large truck capable of carrying a number of ton bags 50 and may be, for example, a 24-ton truck.

Ton bags 50 filled with the desired amount of catalyst can be transported near the main ship by a transport truck 80. Near the main line, there may be a mounting space 140 where a number of tone bags 50 can be mounted. The mounting space 140 may be provided, for example, on a quay wall where a ship is being built or a ship in operation is anchored.

Movement from the transport truck 80 to the mounting space 140 can be accomplished using a forklift.

A secondary loading step (S230) of loading the ton bags 50 loaded in the holding space 140 onto the main ship can be performed by putting them into the vessel 160 of the main ship using the main ship crane 150.
