Description

Prismatic pressure vessel having beam lattice

The present invention relates to a pressure tank, and more particularly, a reinforcing member having a beam lattice structure in a pressure tank of a hexahedron can withstand the pressure caused by gas, and is manufactured in a square shape to have a space efficiency and a material ratio. It relates to a pressure tank having a beam lattice structure that can increase the.

In general, liquefied natural gas (LNG) is known to be a clean fuel and abundant in reserves than petroleum, and its use is rapidly increasing with the development of mining and transportation technology.

In addition, fixed and floating offshore production facilities, offshore production and storage facilities for storage and use of liquefied natural gas (LNG), waterborne transport using ships, fixed and floating offshore inflow terminals and regasification facilities, and onshore inflow terminals and recovery The demand for fire facilities is increasing.

Offshore production facilities and inlet terminals are emerging as new areas in the LNG chain, and a number of projects and ideas are currently being studied.

LNG선에 대한 통상적인 건조 시간은 주요 병목 사항으로서 탱크 시스템의 건조 및 시험으로 인하여 약 20개월 또는 그 이상이다.Long drying times are one of the major problems for existing tank systems. 145000

Typical drying times for LNG carriers are a major bottleneck and are about 20 months or longer due to the drying and testing of tank systems.

Another problem is that the tank structure is subjected to high dynamic pressure due to the wave generated by the motion of the structure and the wave and dynamic motion of the fluid, the magnitude of the dynamic pressure being dependent on the filling rate of the contents, Occurs more severely. This important effect, called sloshing, can cause structural problems in most conventional tanks.

Another challenge for tank systems arises from storing liquefied natural gas as the propulsion fuel for ships. In order to use it as a propellant fuel, liquefied natural gas must be mounted on or inside the ship for a long time, and heat penetration from the outside occurs as time passes, thereby increasing the pressure inside the tank. For this purpose, the storage tank must be a pressure vessel with pressure resistance.

The need for such large pressure vessels is also required for carbon dioxide vessel transportation. Unlike liquefied natural gas that can be liquefied at atmospheric pressure by lowering the temperature, carbon dioxide must be compressed to about 6 atm or higher to liquefy. Therefore, a large pressure vessel as a cargo tank is essential for ship transport of carbon dioxide.

For offshore production facilities, the shape of the tank is very important when the tank is located inside a structure that typically has processing equipment on decks above the facility.

Another important aspect for offshore production facilities is manufacturing and installation. The prefabrication of the tank to be transported to the drying site in one piece or a small number of pieces can reduce the drying time and the associated costs.

Fully prefabricated tanks can also be leak tested before being installed. Conventional membrane tank systems are complex to dry and typically require 12 months or more of drying time, and final structure completion must be performed at the drying site.

For waterborne transport on vessels, the tank system of the membrane tank system and Moss spherical tank system by GTT (Gaz Transport et Technigaz, France) opened the market. Is leading.

The self-supporting SPB tank developed by IHI (Ishikawajima-Harima Heavy Industries Co. Ltd., Japan) is another possible tank system.

The Mohs spherical tank concept was initially developed from 1969 to 1972 using aluminum as the low temperature material.

This design is an independent tank with a partial second barrier. Insulation is typically a polymer foam that is applied to the outer surface of the tank wall. For ships and offshore installations, the Mohs spherical tank concept is limited in volume available by the spherical shape and therefore relatively low in volume efficiency, and is not suitable for installations that require many flat decks on the installation.

Development of the membrane tank system began in 1962 and was further developed by Technigaz. The current system consists of a thin stainless steel or Invar steel first barrier, an insulating layer of a pearlite filled plywood box, an Invar steel or Triplex second barrier and finally a second insulating layer. The stainless steel membrane is corrugated to handle the heat shrink and expansion of the membrane and the Invar steel membrane does not require any corrugation.

For drying, the system is complicated due to the large number of specific parts and a significant amount of welding.

Welding of the membranes and corrugations can be deformed into stress concentrations and stress changes due to both fatigue and sloshing offer potential for leakage. Sloshing that occurs in partially filled tanks can cause leaks in such tanks, so typically 10% to 80% filling is not allowed in sailing conditions.

Sloshing generally provides very high dynamic pressure on the inner wall of the membrane tank, especially in the corner region, which can damage the membrane and the lower insulation. Another weakness is the inability to inspect the second barrier.

The Self-Supporting Prismatic Type-B (SPB) tank developed by IHI is an independent cuboid tank with a partial second barrier designed as a conventional orthogonal reinforcement plate and frame system. Insulation attached to the tank and the outer surface of the tank is disposed on a system of wooden block supports.

The system consists of plates and reinforcement systems consisting of reinforcements, frames, girders, stringers and bulkheads as in conventional designed ship structures. By this structural factor, sloshing is not a problem. On the other hand, fatigue due to significant amounts of internals and local stress concentrations is a problem for such tank systems.

Mobil Oil Corporation has developed a boxed polygon tank for the storage of LNG on land or above ground structures, described in patent application PCT / US99 / 22431.

The tank includes an inner, truss-supported, rigid frame with a cover on the frame to reliably store the stored liquid. The inner, truss-supported, rigid frame is specially designed for the interior of the tank to withstand the dynamic loads generated by the sloshing of the stored liquid due to the short stimulus generated by the seismic activity.

The tank is prefabricated into sections and assembled on site. The tank structure has a number of details and stress concentrations discussed for fatigue life.

For onshore inflow terminals and regasification plants, the market is dominated by cylindrical tanks constructed as single barrier, full barrier or double barrier tanks. The single barrier tank includes an inner tank and an outer tank. The inner tank is a cylindrical wall made of low temperature material, usually 9% Ni steel and with a generally flat bottom. Prestressed concrete and aluminum are also used as internal tanks. The outer tank is generally made of carbon steel which only has the function of keeping the insulation in place and cannot provide significant protection in case of destruction of the inner tank.

Most of the LNG storage tanks manufactured recently in the world are designed as double or full barrier tanks. In this design, the outer tank is designed so as not to leak the contents of the inner tank in case of destruction of the inner tank. For a complete barrier tank, the outer tank or wall is typically dried as a compressive stressed concrete wall spaced 1-2 meters apart from the inner tank with insulating material.

Conventional dried onshore LNG tanks are expensive and must be manufactured in a place with a build time of about one year and where significant local infrastructure is required.

As can be seen in Table 1, the volumetric efficiency of the cellular tank is the most efficient, the material ratio has a similar value for the cylindrical tank, lobe tank, and the cellular tank.
