Definitions
- the invention relates to a method for producing a system for carrying out a low-temperature air separation process, in which at least one component of the feed air is obtained as a product by means of a selected process variant, the system having at least one cold box in which at least one module is arranged.
- Cryogenic air separation plants extract large quantities of oxygen, nitrogen, argon and possibly other noble gases from the separation of ambient air.
- Such systems are designed on the basis of the product specifications specified by the customer.
- the customer defines the product types he wants, for example oxygen, nitrogen and argon, their respective quantities, pressures and purities, whether the products are to be obtained in gaseous and / or liquid form, and the dynamics of the system when converting and changing production.
- the manufacturer of the system selects a specific air separation process or a specific process variant, the system components required for this, such as machines and apparatus
- the object of the present invention is to provide a method for producing a
- This problem is solved in a method of the type mentioned at the outset by predefining several size classes, one size class defining the dimensions of the cold box of this size class and the cold box of each size class being so large that the module in the cold box for at least two different product quantity requirements and / or at least two different process variants can be accommodated, and that a cold box of a certain size class is selected and the module is arranged in the cold box of the selected size class.
- Cryogenic air separation plant conceptually divided into modules, accessories and piping.
- the modules include all components that enable one of the functions specific to air separation. These are especially machines such as Compressors, compressors, expansion machines and cryogenic pumps, devices for air purification, e.g. Mol sieves and adsorbers,
- Heat exchange devices such as Main heat exchangers, main condensers, top condensers, secondary condensers and supercooling counterflow devices, as well as air separation devices such as counterflow devices and rectification columns.
- a "cold module” is understood to mean a module which is provided with thermal insulation, a so-called cold box.
- the individual modules of an air separation plant have been selected taking into account the product specifications requested by the customer and the air conditions at the installation site, as well as on the basis of additional conditions such as legal regulations and standards.
- the cold modules i.e. The modules that need to be thermally insulated and their accessories were then placed individually or in groups in one or more cold boxes, which were precisely adapted to the dimensions of the modules or groups of modules.
- the dimensions of the cold box or cold boxes, in which one or more of the modules to be thermally insulated are accommodated, are no longer designed precisely for the modules. Rather, several size classes of cold boxes are predefined, so that only a limited number of cold box sizes are available.
- the modules planned for the low-temperature air separation plant to be manufactured are first selected.
- the cold modules to be housed in cold boxes are divided into groups. The groups are preferably classified in such a way that, after the module groups are arranged in the cold boxes, one or more transportable units result, and preferably in such a way that functional units are created.
- the pressure column, the low pressure column and the main condenser are combined to form a nitrogen-oxygen rectification unit.
- a size class is then selected in accordance with the modules or module groups to be insulated and the modules are placed in a cold box with the dimensions of the selected size class.
- the individual size classes are determined beforehand, regardless of the current system designed based on customer specifications.
- each module or module group that occurs with the different process variants and system sizes is assigned a fixed cold box size.
- the size classification according to the invention will be illustrated using the following example.
- Five size classes are predefined, with a first cold box size for the pressure column module, a second cold box size for the low pressure column module, a further cold box size for the argon rectification module and, for example, a fourth cold box size for the energy exchange module with the main heat exchangers being defined within one size class.
- the size, design, arrangement and combination of the individual modules are determined in accordance with customer requirements, the intended air separation process variant and the other boundary conditions. This results, for example, in a pressure column module with certain dimensions.
- the class to be used is selected by comparison with the predefined size classes and the cold box size defined in this class for the pressure column module is used.
- the cold box sizes in the individual size classes are defined in such a way that despite the restriction to just five sizes, a large number of process variants and product quantity requirements, in which the pressure column module differs in terms of size and accessories, are covered.
- the selected cold box is therefore not exactly adapted to the specific process variant and the modules with accessories used in the special application, but only a selection from the limited number of possible cold box sizes.
- the selected cold box is not the optimal solution for isolating the module used.
- the material costs for the cold box will be somewhat higher than that of a cold box, which is exactly adapted to the parts to be insulated in the usual way.
- the definition according to the invention of certain size classes enables engineering savings to be achieved which exceed the higher material expenditure and thus bring overall cost advantages.
- the individual size classes are selected so that at least two different product quantity requirements and / or at least two different process variants are covered by each size class.
- the process variants differ, for example, by the products obtained, the type of product compression, the product pressures, the product purities, the ratio of liquid to gas or the ratio of oxygen product quantity to nitrogen product quantity.
- the pressure column, the low pressure column or the entire nitrogen-oxygen rectification module and the respective accessories are preferably introduced into a cold box, which is selected regardless of the type of product compression.
- a cold box which is selected regardless of the type of product compression.
- an external compression of the products i.e. a compression of the gaseous product, as well as a
- the size classes are also advantageously selected so that the cold box sizes of the pressure column module, the low pressure column module or the nitrogen-oxygen rectification module are selected regardless of whether a crude argon column and, if appropriate, further columns are to be connected to the low pressure column or not. Furthermore, it is favorable for at least two process variants in which the products are obtained with different pressure or different purities or for two processes in which the ratio between the gaseous product quantity and the liquid product quantity varies or for two processes with a different ratio of product oxygen quantity to product nitrogen quantity to provide the same cold box sizes.
- a cold box of one size class is suitable for storing the associated modules and their accessories of at least 5, preferably at least 10 different ones
- the cold box is designed so that each of the process variants, but not necessarily all process variants, can be covered at the same time.
- the size classes are selected so that at least two different ones
- Process variants and / or two different product quantity requirements can be covered with a cold box of one size. Two product quantity requirements are considered different if the generation of the required product quantities has different effects on the design and / or size and / or number of the required modules and / or their accessories.
- the invention has advantages if all modules are arranged in exactly one cold box, and if at least two cold boxes are provided for the modules.
- several size classes are defined for the cold box, in which all modules to be thermally insulated can be accommodated.
- a certain size class is selected, whereby the same size class is also suitable for other process variants or product quantity requirements.
- each size class only includes a single cold box size.
- the cold modules are distributed over several cold boxes, a specific size of the corresponding cold box is defined for each module or each group of modules that are to be accommodated in their own cold box. For example, all cold modules are converted into an energy exchange module with the heat exchangers, a rectification module with the Rectification columns and an accessory module with all other elements divided, so each size class specifies the dimensions of three cold boxes corresponding to the modules mentioned.
- the same size class is preferably chosen for all cold boxes.
- the cold boxes of the same size class intended for different modules or module groups are particularly preferably provided with defined interfaces.
- the connection points for the piping, instrumentation, electrical supply, etc. are determined regardless of the specific process variant. Not only the dimensions of the cold box / s, but also their connection points are defined within a size class.
- the individual cold boxes with the modules can always be easily connected to each other in an analog manner without additional engineering effort.
- argon module it is also convenient to accommodate the various modules of an air separation plant in cold boxes that are assigned to different size classes. If, for example, the customer requires only a relatively small amount of argon and therefore the maximum possible amount of argon is not to be obtained, a correspondingly smaller argon module is used. In this case, it makes sense to select the cold box for the argon module from a lower size class than the cold boxes for the pressure column and low pressure column modules or for the oxygen / nitrogen rectification module.
- connection points for the piping regardless of the design of the module to be accommodated in the cold box, but also independently to define the interfaces from the size class.
- the connection points for the electrical supply lines and the instrumentation can, for example, always be arranged on the side of the cold box opposite the pipe connections.
- the connection points of the cold boxes are selected so that the connection of the cold boxes with each other or with other components or
