Definitions
- the present invention relates to a method and an installation for producing argon by cryogenic distillation.
- a flow enriched in argon is withdrawn from the low pressure column of a double air separation column and sent to the bottom of a first column in order to lower as much as necessary the quantity of oxygen contained in the oxygen. product.
- the argon produced by this first column is drawn off at the head and contains most of the nitrogen introduced into the feed. It is then customary as seen in EP-A-0669509 and EP-A-0669508 to send it in a second column called denitrogenation column comprising a depletion section intended to remove the nitrogen from the argon produced in the tank, a rectification section intended to remove the argon from the residual nitrogen withdrawn at the top, a tank reboiler and a condenser at the top.
- denitrogenation column comprising a depletion section intended to remove the nitrogen from the argon produced in the tank, a rectification section intended to remove the argon from the residual nitrogen withdrawn at the top, a tank reboiler and a condenser at the top.
- US-A-5133790 describes a system in which enough distillation trays are installed in the low pressure column, above the point of withdrawal of the feed from the first column, to lower the nitrogen content in proportions such that the argon produced has a 'commercial' argon content, generally 1 ppm.
- the column of denitrogenation can be removed. It is then useful to have a few distillation trays above the point of withdrawal of the argon-rich fluid from the first column and to provide a purge at the top of the first column in order to eliminate part of the nitrogen introduced. Under these conditions, the nitrogen content of the argon produced may be approximately three times lower than that of the column feed.
- the disadvantage of this process is that it is essential to control the operation of the low pressure column so that never the nitrogen content at the point of withdrawal of the feed intended for the first column does not exceed the admissible quantity, unless the column has enough trays to have at the nominal point a sufficient margin with respect to this limit.
- US-A-4977746 and US-A-4824453 disclose a method for producing argon and ultra pure oxygen in which a liquid taken from an intermediate level of the argon production column feeds the head of a column of exhaustion in the tank from which ultra pure oxygen is formed.
- the flow rate sent at the head of the second column can be a gas or a liquid.
- the circulating gas is a fraction of the gas enriched in argon which feeds the first column.
- the first column is in two sections, one section being supplied by the gas enriched in argon and the other having the overhead condenser.
- the first column is supplied from the low pressure column of a double column.
- a head gas from the second column is sent either to the head of the first column or to the head condenser of the first column.
- an installation for separation of a gas enriched in argon by cryogenic distillation comprising:
- the argon-rich fluid sent to the head of the second column can be a gas or a liquid.
- Preferably it comprises means for sending part of the gas enriched in argon to the tank reboiler as circulating gas.
- the first column is constructed in two sections.
- the installation comprises means for sending a head gas from the second column either to the head of the first column or to the head condenser of the first column
- an air flow 100 is sent to a conventional double air separation column comprising a medium pressure column 200 thermally connected to a low pressure column 300. Part of the details in this column have been omitted to facilitate the presentation of the invention.
- a flow 5 enriched with argon containing 7% argon, a few ppm of nitrogen and oxygen taken from the low pressure column 300 is sent to the tank of the first section 7 of the first column 1.
- a liquid flow 6 is returned from the tank of the first column to the low pressure column.
- the first section 7 containing structured packings of the cross corrugated type is used to separate the flow enriched in argon.
- a top gas 9 of the first section is sent to the tank of the second section 11 and a tank liquid of the second section is sent to the top of the first section 7 to serve as reflux.
- the head gas from the first column is at least partially condensed in an overhead condenser 15 ′ against rich liquid from the tank of the medium pressure column or another fluid.
- a purge 13 of non-condensed argon-rich gas can be removed. As it cannot be rich in nitrogen for temperature reasons, the loss of argon will be proportional to the quantity of nitrogen introduced in the first section 7.
- a liquid flow rich in argon 15 containing argon and at most 1000 ppm of nitrogen and 1000 ppm of oxygen is withdrawn from a few theoretical plates below the head condenser, for example, three theoretical plates below.
- the liquid 15 is sent to the top of the second column 2 in which it is enriched in argon.
- the overhead gas 17 enriched in nitrogen is returned to the second section 11 of the first column.
- a liquid 21 or a gas rich in argon 23 is withdrawn from the tank of the second column 2.
- the gas enriched in argon can come at least partially from an apparatus other than the double column 200, 300.
- an apparatus other than the double column 200, 300 For example it can be transported by truck or by pipeline from a more distant apparatus.
- columns 200, 300 and 7 are identical to those of FIG. 1.
- the head gas of column 11 is withdrawn therefrom, mixed with the head gas of column 2 and sent to the capacitor 18 which contains the condenser 15 '.
- the gas mixture at least partially condenses in this condenser before being returned in liquid form to the head of column 11.
- This system avoids the complexity of creating an additional feed in the first column 11, without significantly affecting the production of argon.
- This way of implementing the invention is particularly profitable when the argon condenser and its capacity are separated from the first column.
- the process does not use catalysis to purify the argon.
