Definitions
- the invention relates to a method according to the preamble of patent claim 1.
- a liquid pressurized oxygen product stream is vaporized against a heat carrier and finally recovered as a gaseous pressure product.
- This method is also called internal compression. It serves for the production of pressure oxygen. In the case of a supercritical pressure, no phase transition takes place in the true sense, the product stream is then "pseudo-evaporated".
- a high-pressure heat carrier is liquefied (or pseudo-liquefied when it is under supercritical pressure).
- the heat transfer medium is often formed by part of the air, in the present case by the "second partial flow" of the compressed feed air.
- the invention has for its object to provide a method of the type mentioned above and a corresponding device that work energetically particularly favorable.
- the inlet temperature of the cold compressor is for example 2 to 50 K,
- the method is particularly favorable when the oxygen product pressure ("second elevated pressure") is between 20 and 40 bar.
- the pressure ratio at the cold compressor is preferably 1.4 to 2.1, the "first elevated pressure" between 10 and 30 bar.
- the method can be carried out with a single expansion machine.
- a dissipative brake, a generator or a warm compressor with the cold compressor, a dissipative brake, a generator or a warm compressor.
- Relaxation machine coupled to produce the necessary for the process cold.
- a second expansion machine can be operated with a suitable process stream, which takes over the task of cooling.
- the work-performing expansion of the first partial flow is carried out in two parallel or serially connected expansion machines.
- Compressor and the other with a warm compressor, a generator or a dissipative brake be coupled.
- the two expansion machines have the same inlet temperature and / or the same Inlet pressure or the same outlet pressure and / or the same
- mechanical energy of both expansion machines is used to drive the cold compressor.
- Relaxation machines are thus mechanically coupled to the cold compressor (and optionally in addition to a warm compressor, a generator or a dissipative brake).
- two serially connected turbines are used, which are mechanically coupled to each other, for example via a common shaft, or a
- Turbine wheels in a common housing which drive a common shaft and thus constitute a unit.
- the common wave drives the
- Cold compressor and optionally another braking device for example, a dissipative brake, a generator or a warm compressor.
- Main heat exchanger is performed.
- the "main heat exchanger” may be formed of one or more parallel and / or serially connected heat exchanger sections, for example one or more plate heat exchanger blocks.
- the invention also relates to an apparatus for producing a gaseous print product by cryogenic separation of air according to claims 8 to 13.
- Distillation column system not shown.
- the latter is preferably formed by a conventional two-column system for nitrogen-oxygen separation.
- 1 shows a first embodiment of the invention with combination machine and Figures 2 to 5 further embodiments in which only one expansion machine drives the cold compressor.
- air 1 flows from the main air compressor and the subsequent air cleaning (both not shown) under very high pressure and is divided into a first partial flow 2 (turbine flow) and a second partial flow 3 (throttle flow).
- the first partial flow 2 is introduced into a main heat exchanger 10 at its warm end. At an intermediate temperature of the first partial flow is removed again via line 4 and then expanded in a first turbine 5 work to an intermediate pressure.
- the intermediate compressed air 6 is warmed up again in the main heat exchanger 10 (intermediate heating) and fed via line 7 to a second turbine 8 and working there from the intermediate pressure to approximately the operating pressure of the high-pressure column of the distillation column system (not shown).
- the exhaust air 9 of the second turbine 8 is fed to the high-pressure column as essentially gaseous feed air.
- the second partial stream 3 is passed under the very high pressure to the cold end through the main heat exchanger 10 and thereby supplies the heat for a pressurized or pseudo-evaporating oxygen product stream, the liquid (51 - LOX) removed from the distillation column system and was brought in a pump 52 to a "first elevated pressure" of 19.5 bar. (The other return flows through the main heat exchanger are not shown here.)
- the cold second part stream is expanded in a throttle valve 11 to about high pressure column pressure and introduced liquid or as - two-phase mixture in one or more columns of the distillation column system.
- the two turbines 5, 8 are mechanically coupled, via a common shaft 12, which drive both of them. On this shaft also sits a cold compressor 13, which is generated by means of the turbines and transmitted to the shaft 12 mechanical energy is driven.
- the shaft also drives a dissipative brake, a generator or a warm compressor (not shown).
- the vaporized product stream 53 is withdrawn from the main heat exchanger 10 at an intermediate temperature of about 5 to 10 K above the (pseudo) evaporation temperature and fed to the cold compressor 13. There it is further compressed from the "first elevated pressure” to a “second elevated pressure” of 33 bar. He comes out of the cold compressor at a temperature which is 15 to 30 K higher than the inlet temperature (line 54) and then at the appropriate place again
- the two expansion machines are connected in parallel.
- the first partial flow 4 below the intermediate temperature is thereby split into two branch streams 204, 207, which are in each case expanded in only one of the turbines 205, 208 to perform work.
- the two relaxed air flows are reunited and, as shown in FIG.
- the two turbines are designed as two separate machines.
- the first turbine 205 drives a warm compressor 223 via a first common shaft. This is designed as a re-compressor for the compressed in the air compressor not shown use air 1. This is followed by an aftercooler and the recompressed air is fed via line 201 to the warm end of the
- the second turbine 208 drives the cold compressor 13 for the (pseudo) vaporized product stream 53 via a second common shaft.
- FIG. 3 differs from FIG. 2 in that not the total air 1 is recompressed, but only the second partial stream 303, 3.
- the feed air 1 compressed in the air compressor is already divided into the first partial stream 2 and the second partial stream 303 before the secondary compressor 323 and only the second partial stream 303 supplied to the after-compressor 323.
- Partial flow 3 is finally performed as before to the warm end of the main heat exchanger 10 and forms the inductor current.
- FIG. 4 shows a further modification of FIG. Here, the compressed feed air upstream of the post-compressor 223 in an additional
