| PROBLEM TO BE SOLVED: To provide a method and equipment for low temperature separation of air which enable attainment of stable operations in a full load state and an insufficient load state, while maintaining a sufficient pressure difference for a transfer fraction between a high- pressure tower and a low-pressure tower or between the high-pressure tower and an evaporation chamber of a condenser in the top of a crude argon tower even when the structural height of a fractionator is large due to the use of a low-pressure-loss filling, and which enable avoidance of useless consumption of gas resources as relaxation gas, in particular, on the occasion. SOLUTION: Source air 1 is introduced into a fractionator 3 and transfer fractions 6 and 7 of concentration ρ are taken out as liquids from reservoirs in the fractionator and sent to separate processes 5 and 23 after expansion 14, 14a and 18. A liquid level in the reservoirs 24 and 16 is under a first pressure p1 at a first level h1, while fractions after the expansion are supplied to the separate processes 5 and 23 under a second pressure p2(p2<p1) at a second level h2 (h2>h1). The difference Δp=p1-p2 between the two pressures is smaller than the liquid-column Static pressure (phydr=p.g.[h2-h1]) of the fractions between the first and second levels. The expansion is executed within the range wherein Δp is large enough to supply the fractions to the separate processes 5 and 23 and in such a manner that bubbles generated in the expansion may reduce the concentration of the fractions.

| PURPOSE: To economically restart the operation of a main heat exchanger, by positioning the heat exchanger in such a way that the exchanger is at least partially dipped in a liquid when the operation of an air distillation double column is stopped and, at the same time, providing an auxiliary heat exchanger suitable for only guaranteeing the vaporization of the liquid. CONSTITUTION: When the operation of a facility is stopped, a liquid rises to a level N1 and a heat exchanger 7 is dipped in the liquid. When the operation is restarted, a pump 15 raises the liquid to an upper liquid receiver 25A, because a valve 26B is closed and another valve 26A is opened. Part of the flow rate is vaporized and the liquid gradually descends in the liquid reservoir of a low-pressure column. When the liquid nearly returns to a level N, the heat exchanger 7 is newly actuated. When the operation is restarted, in addition, a valve 27B is closed and the pump 15 raises the liquid in a supply box 27. As a result, an overpressure is generated in the box 27 and allows the oxygen vaporized in an auxiliary heat exchanger 20B to exceed the pressure of an underlying liquid bath. The liquid gradually descends in the liquid reservoir of the low-pressure column together with the pressure in the supply box 27 and, when the liquid nearly returns to the level N, the heat exchanger 7 is restarted and the valve 27B is opened.

| Krypton and/or xenon is separated crudely from a mixture (100) comprising oxygen and at least one rare gas selected from the group consisting of krypton and xenon in a process comprising feeding said mixture (100) or a mixture (108) derived therefrom to a rare gas recovery system (16) and separating said mixture feed (108) in said rare gas recovery system (16) into rare gas-lean gaseous oxygen ("GOX") (110) and rare gas-enriched product (120). The process is characterised in that at least about 50 mol % of said mixture (108) is fed to the rare gas recovery system (16) in the gaseous phase and when said mixture feed (104,106) is separated by selective adsorption, the concentration of xenon in the mixture feed is no greater than 50 times the concentration of xenon in air. One advantage of a preferred embodiment of the present invention is that it can easily be retrofitted to existing pumped LOX cycle ASUs. |

A pump 40 is provided for pumping a stream of sump liquid of the lower pressure column 12 to produce a pressurised product. Liquid is recirculated back to the condenser-reboiler by an ejector 48 that uses part of a pumped stream as the motive fluid to draw in liquid for recirculation. In such manner, less energy is consumed in the recirculation than had all of the recirculated liquid been pumped by the pump 40. |

| PURPOSE: Process and apparatus for the low-temperature fractionation of air is provided, which enable attainment of stable operations in a full load state and an insufficient load state. CONSTITUTION: The process and the apparatus serve for the low-temperature fractionation of air. Feed air(1) is introduced into a first rectification column(3). A transfer fraction(6, 7) of density rho is withdrawn in the liquid state from a reservoir(24, 16) within the first rectification column(3), expanded(14, 14a, 18) and fed to a further process step(5, 23). The liquid level in the reservoir(24, 16) is in this case at a first level h1 and is at a first pressure p1. The expanded transfer fraction is fed to the further process step(5, 23) at a second, higher level h2(h2 >h1) and at a second, lower pressure p2. | ||||||
