- Figure 1 illustrates a cut away view of an air distillation plant according to one embodiment of the invention.
- the invention and its corresponding embodiments, is described below in relation to cold boxes containing an air separation unit, but also applies to cold boxes containing additionally, or alternatively, at least one storage tank for cryogenic liquids.
- the air distillation plant comprises a main cryogenic element, such as a high-pressure column 1 and a low-pressure column 3, which are thermally integrated.
- the two columns are placed within an outer jacket 7 having a circular cross section.
- the outer jacket 7, also referred to herein as the cold box, is made of resilient metal, such as stainless steel or aluminum, is placed on top of a metal framework, sometimes known as a "pancake", which is fastened to the deck 27 of a ship or floating platform.
- Cooled compressed air to be sent to the high-pressure column is sent to a heat exchanger (not shown) outside the cold box via piping duct 9.
- the piping duct also carries conduits containing product and waste steams from the columns.
- One of the products is a pressurised liquid oxygen stream, which is to be vaporised in the heat exchange line.
- the liquid oxygen is removed from the low-pressure column, pressurised by an auxiliary element 16, such as a pump, and sent to the piping duct 9 in a conduit.
- the pump is located in a housing 13, which extends through an opening in the outer jacket such that the housing is directly accessible from outside the outer jacket 7.
- the housing 13 is made of resilient metal, such as stainless steel or aluminium.
- the space between the cold box and the columns is filled at least partially with particulate insulation material, such as perlite.
- the cold box illustrated has a circular cross-section, but any cross- section could be used.
- the low-pressure column 3 is placed on a structure 11 so as to prevent cold migration to the ship or platform deck 27, which could cause the carbon steel structure of the ship to fracture.
- the high-pressure column 1 is similarly insulated from the deck.
- the housing 13 is sealed into an opening in the outer jacket 7, preferably welded to the inner wall 31 , such that the perlite cannot escape.
- the housing is insulated from the interior of the cold box using a rock wool layer 15 and a non-resilient metal wall 17, such as an expanded metal layer. These layers form a weak link, which will break in the case of over-pressure allowing the liquid oxygen to flow back into the cold box 7.
- the housing 13 is in the form of a cuboid that has an inner space 14 and a base wall 29 which slopes downwards towards the deck 27 of the ship, to assist the flow of any leaking liquid oxygen back into the cold box 7 after breaking through the metal wall 17.
- the housing may have any suitable shape.
- the base 12 of the cold box is insulated using a layer of foam glass 19 covered by a sealing plate 21.
- the bottom of both column structures 11 is partially filled with a layer of rock wool 23.
- the cold box may also be opened via an access door 25.
- the housing 13 is insulated using perlite or rock wool and as well as (or instead of) a pump or pumps and their associated piping may contain at least one turboexpander and/or at least one valve and/or other piping.
- the outer jacket 7 has an inner wall 31 and an outer wall 33, at least part of the space between the two being filled with perlite 35 in loose form or in the form of bricks. If the insulant is in the form of bricks, the inner wall of the jacket may be formed by the sidewalls of the bricks or may be a separate panel.
- the sealing plate 21 and inner walls 31 of the outer jacket are impervious to liquid, so that if any cryogenic liquid escapes from the air separation unit will collect in the bottom of the cold box and eventually evaporates or is vaporised using a vaporiser.
- a relief valve may be provided so that vapors leaking from the cryogenic unit may escape from the outer jacket.
- the air separation unit may have any number of columns.
- it may comprise a single column, a double column, or a triple column.
- a mixing column or an argon production column may be used.
- the invention has been described in relation to cold boxes containing an air separation unit, but also applies to cold boxes containing additionally or alternatively, at least one storage tank for cryogenic liquids. It also applies to cold boxes containing a liquefier for producing cryogenic liquids.
- the air separation unit could be replaced by any cryogenic distillation unit, such as a unit for separating a mixture having principal components in the group comprising hydrogen, helium, methane, nitrogen, and carbon monoxide.
- cryogenic distillation unit such as a unit for separating a mixture having principal components in the group comprising hydrogen, helium, methane, nitrogen, and carbon monoxide.
- the methods to make such a replacement are well known to those skilled in the art.
- the invention also relates to cold boxes in which cryogenic liquids other than oxygen is pumped, such as nitrogen.
- cryogenic liquids other than oxygen is pumped, such as nitrogen.
- the skill to do such an application is well known to those skilled in the art.
