Definitions
- the present invention relates to a method of transfer of a liquid, via a riser fitted an expansion valve, a first column of distillation operating at a first press, typically relatively high, to equipment, especially to a second distillation column, operating at a second press, typically relatively low, less than the first press.
- Apparatuses for the separation of gases from air by distillation cryogenic most often use the scheme classic double column. Liquids produced in tank (liquid rich in oxygen), in the middle (lean liquid) and at the top (liquid nitrogen) of the column medium pressure (or MP column), are sent at an intermediate point or at the top of the column low pressure (or BP column). Most of the time, for economic reasons, the low pressure column is placed above the medium pressure column. It is therefore necessary to send liquids to a point located higher than the point where they are taken. Conventionally, the pressure difference between the average column pressure and the low pressure column is higher at hydrostatic pressure of the liquid column between the sampling point in the column MP and the end point of the BP column.
- the invention aims to allow, in a simple way and efficient, safe transfer of liquids, without use of a pump.
- the method according to the invention is characterized by injecting it into the riser, downstream of the expansion valve, a lightening gas available at a pressure higher than the pressure created by a column of said liquid between the injection point of the gas and the point of introduction of the liquid into said equipment.
- the invention relates to a process for transferring a liquid, via a pipe rising fitted with an expansion valve, a first distillation column operating at a first pressure on equipment, especially one second distillation column, operating at a second pressure, less than first pressure, characterized in that the liquid is sub-cooled before its expansion, at except for a minority fraction of this liquid, so as to produce a controlled amount of gas from flash, this flash gas is injected downstream of the expansion valve and serves as a lightening gas for the liquid.
- this installation also relates to an installation distillation intended for the implementation of such a process.
- this installation of type comprising a first distillation column operating at first pressure, equipment, in particular a second distillation column, operating at a second press, less than the first pressure, and a riser fitted with a expansion valve and connecting a liquid withdrawal point from the first column to an introduction point of liquid in said equipment, is characterized in that that it includes means of injection into the pipe rising, downstream of the expansion valve, by a lightening gas available at higher pressure at the pressure created by a column of said liquid between the gas injection point and the point of introduction of the liquid in said equipment.
- the invention relates to an installation according to claim 10.
- the air distillation installation shown in the figure 1 essentially comprises a double column distillation 1.
- This includes a medium column pressure 2 surmounted by a low pressure column 3.
- a vaporizer-condenser 4 puts in exchange relation thermal steam at the top of column 2, consisting practically pure nitrogen, and the tank liquid column 3, consisting of oxygen at a determined purity.
- Porture liquid (impure nitrogen) is drawn off in one intermediate point of column 2 via line 11 equipped with an expansion valve (not shown) and, after sub-cooling and expansion, is introduced in an intermediate point in column 3. Liquid nitrogen practically pure is withdrawn at the head of column 3 via a pipe 12 fitted with an expansion valve 13, sub-cooled in a sub-cooler 14 upstream of this expansion valve, relaxed in the latter and introduced at the top of column 3.
- an air line 19 is tapped into supply line 5 and splits into two branches 20, 21.
- Each of these branches is equipped with an expansion valve 22, 23 and joined respectively lines 6 and 9 just downstream of their expansion valves 7 and 10.
- a pipe 24 gas equipped with a relief valve 25 starts from the top from column 2 and joins line 12 just by downstream of the expansion valve 13.
- Another line for gas 26, fitted with an expansion valve (not shown), starts from a location in column 2 next to the point of withdrawal of the poor liquid (line 11) and joined this pipe 11 just downstream of the expansion valve of it.
- a low flow of conveyed air at the supply pressure of column 2, through the pipe 19, 20, is expanded in the expansion valve 22 and injected into the newly expanded rich liquid in the expansion valve 7.
- the air bubbles lighten the rich liquid and reduce the pressure required for bring up to column 2.
- a low air flow conveyed by line 19, 21 is relaxed in the expansion valve 23 and injected into the rich liquid which has just been expanded in the expansion valve 10.
- the total diverted air flow via line 19 is weak, typically less than 1 % of the air flow entering the installation.
- the lightening gas corresponding in line 24 must be nitrogen practically pure.
- the compositions of the liquid rich and poor liquid are not critical, so that the corresponding lightening gases can have somewhat different compositions from these liquids, provided that they do not pollute them, all the more more than the flow of these gases is very low.
- the main expansion valves 7, 10 and 13 are placed as low as possible to guarantee feeding them with frank liquid, and we introduce gas bubbles just downstream of these valves trigger to assist the upward propulsion of liquids in question. More specifically, the pressure of lightening gas must be sufficient to overcome the height of liquid above the injection point of the gas, and this pressure is obtained, in the example shown, thanks to the fact that every gas, which is available at the pressure of column 3, is injected above the point of withdrawal of the associated liquid.
- FIGS 2 and 3 illustrate, in the case of the ascent liquid nitrogen via line 12, two variants obtaining lightening gas. In these two variants, the pipe 24 and the expansion valve 25 are eliminated.
- a minority flow control of liquid nitrogen conveyed by line 12 bypass the sub-cooler 14 via a bypass pipe 24A fitted, preferably at its lowest point, an expansion valve 25A and ending downstream of the expansion valve 13.
- the expansion valve 25A is deleted, and there is provision, in line 12, a three-way valve 27 having an input connected to the line 12 upstream of the sub-cooler 14, an outlet connected to the input of this subcooler and another output connected to the 24A bypass line.
- this pipe 24A ends upstream of the expansion valve 13.
