Modular process plant, in particular air separation plant with a variety of plant components

description

The invention relates to a modular process plant, in particular air separation plant with a plurality of plant components and at least one operating unit, the plant components ready pre-assembled in containers with standard dimensions

accommodated, transported in the container and functionally connected on site depending on the procedure to be performed and operable in the container network, according to the preamble of claim 1.

From DE 102005006850 AI a system for providing technical gases is already known. In this system, at least one engineering gas is generated in a mobile gas generating unit mounted on a watercraft, the vessel navigating a plurality of land based pick-up points. In one embodiment, the gas generating unit is to be operated while driving between two delivery points and the generated technical gas to be filled into storage containers, which are located on board the vessel. In this case, the gas generating unit includes its own power supply, which is mounted on board the vessel. Details of the accommodation of the function of the gas generating unit determining plant components are not disclosed.

From DE 202009004099 Ul, DE 202009010874 and DE 10 2010056570 AI are methods and apparatus for the recovery of

Pressure oxygen and pressure nitrogen by cryogenic separation of air in a distillation column system for nitrogen-oxygen separation, which has at least one pressure column, previously known.

According to the described method, feed air is compressed in an air compressor. The compressed feed air is cooled in a main heat exchanger and at least partially introduced into the pressure column. Liquid oxygen is withdrawn from the distillation column system for nitrogen-oxygen separation and brought to an elevated pressure in the liquid state. Under this increased pressure, the medium is then in the

Main heat exchanger introduced, evaporated in the main heat exchanger and on Warmed around ambient temperature and finally recovered as gaseous pressure oxygen. A gaseous circulating nitrogen stream is withdrawn from the distillation column system and compressed at least in a cycle compressor. A first partial stream of compressed in the cycle compressor cycle nitrogen flow is then brought in the main heat exchanger in indirect heat exchange with the oxygen flow and

then relaxed. The relaxed first substream of the cycle nitrogen stream is then at least partially introduced in the liquid state into the nitrogen-oxygen separation distillation column system. A second substream is branched downstream of the cycle compressor under a product pressure and recovered as a pressurized nitrogen product.

Usually, such process plants for air separation are mounted stationary and housed in large halls and have a central or decentralized control room.

The resulting liquefied gas products are filled into containers and delivered to customers or consumers. A not inconsiderable share of the total costs is attributable to the necessity of filling and delivering the LPG products.

In the generic DE 2822774 AI a process engineering plant has been proposed, which consists of a variety of components, the components of the plant are ready to be pre-assembled in containers. in the

The containers are then transported to the plant operation site and the plant is connected to the construction site by functionally connecting the plant

Container finished.

Accordingly, the assembly of the individual parts of the system already takes place in the factory. There, the plant is ready for operation mounted in several containers. In this way, the assembly process plant is to be moved from the site to the factory. The aim is to shorten the assembly and commissioning times for such systems and to carry out a functional test of the system at the factory. Particularly advantageous is the teaching of DE 2822774 AI represent in the construction of air separation plants. Plant parts with a high noise emission, such as compressors, should be stored in a closed container be housed, which is soundproofed accordingly. Conveniently, the noise-emitting container should be placed between other containers. Gaps between the containers should also be filled with sound-absorbing material.

However, it has been shown that accommodating the necessary

plant components in containers, especially when commissioning of the system with the components to take place within the container, leading to significant difficulties. The space available in a standard container is naturally limited.

As a result, the accessibility of the individual system components in the case of a necessary maintenance, but also during commissioning difficult.

Furthermore, it is not the noise emission of corresponding plant components, such as e.g. of compressors, superficially, but the resulting operating and waste heat of a variety of plant parts and assemblies. This waste heat must be safely dissipated to the environment under all operating conditions, but also under the most diverse climatic conditions. In this case, such system parts or system components should not be affected, their function only at lower

Ambient or operating temperature can perform.

An additional difficulty arises when the process plant includes such components which are extremely bulky and which must be brought into a changed operating position to perform their function, as described e.g. in an air separation column or

corresponding column is the case.

From the foregoing, it is therefore an object of the invention, an advanced modular process plant with a variety of

Specify system components and at least one control unit, all system components should be housed in a minimum number of standard containers and wherein operation of the system must be possible with the housed in the containers plant components under different climatic conditions without external

Measures, such as a Umhausen be required. The object of the invention is achieved by the combination of features according to claim 1, wherein the dependent claims comprise at least expedient refinements and developments.

It is therefore assumed that a modular process plant, in particular an air separation plant with a variety of plant components and at least one control unit, the plant components ready pre-assembled housed in standard containers and transported in these containers and functionally connected on site depending on the procedure to be performed and in this regard are operable in the container composite.

According to the invention, all plant components are accommodated in two, also airworthy standard containers, with a first container for the selected plant components divided, mutually insulated

According to the invention, a second container is designed such that it has at least one fixed compartment and at least one movable, in particular pivotable, compartment.

Furthermore, attachable to the container connections and fasteners for transporting media and guiding control and operating signals between the containers are available.

In a preferred embodiment, assemblies and plant components with elevated operating temperature and in the second container assemblies and plant components with lower operating temperature are arranged or housed in the first container.

The isolation of the compartments takes place under thermal and / or acoustic aspects in an optimized manner.

Preferably in the first container, a compartment is designed as

provided electrical control and operating room. This compartment is Also suitable for the stay of persons for the purpose of controlling and controlling the respective plant and insofar soundproofed and air-conditioned.

At least the second container has means for aligning and setting up in a planned, in particular flat position.

These means may include trained in the base region of the container, mechanically or hydraulically adjustable feet.

In at least one of the compartments of the first container

Wear and spare parts for the corresponding system components placed.

According to the second container is divided longitudinally, with a part half with its compartment of a horizontal position in the initial state in a vertical operating condition, in particular

hydraulically, is pivotable.

The optional hydraulic control is also located in the second container.

The pivotable part-half of the second container may in particular comprise an air separation tank with liquid-gas buffering.

Furthermore, the container means for venting, heating and / or cooling in such a way that operation in different climates and ambient temperatures in the range of about -25 ° C to + 50 ° C is possible.

In case of operation, the containers can be any position to each other

taking.

At least some of the compartments have a double wall to optimize the thermal and / or acoustic insulation.

On at least one container, a lightning rod and / or a wireless antenna is mounted. Preferably, in the first container, an air compressor is arranged with a heater for flow at startup, especially if the process plant is to be designed as an air separation column.

In this sense, a device for high-pressure filling of liquid gas is located in the second container.

The proposed modular process plant, housed in two standard containers, can be moved by conventional commercial vehicles by land, but also suitable for air freight. All external electrical systems can be carried out in containers with protection class IP 65. Through the compartments provided in the containers

also a longer operation without external spare parts supply of the appropriate process plant can be carried out. Due to the design of pull-out carriages and support profiles, individual components or modules can be easily removed, maintained and reinserted into the appropriate container compartment.

In one embodiment of the invention, the alignment of the movable part takes place in the second container with the alignment or pivoting operation

automatically, so that related adjustments to a

Minimum limit. If one of the system components comprises an activated carbon cleaning insofar as an active carbon absorber, designed as a closed filter cartridge, is carried in one of the compartments and is available for replacement on site. By resorting to a closed cartridge, contamination of the activated carbon in the cartridge due to improper handling on site is precluded.
