Abstract

Die Erfindung betrifft ein Verfahren zum Verdichten eines Gases mit konstantem Druck, konstanter Temperatur und zeitlich veränderlichem Massenstrom auf einen konstanten Enddruck durch dynamische Kompression mit Hilfe einer Turboverdichteranlage (C1...C5), die eine Anlage zur Hauptverdichtung (C2...C5) und eine Anlage zur Nachverdichtung (C1) enthält. Erfindungsgemäß erreicht das Gas bei maximalem Massenstrom bei der Hauptverdichtung (C2...C5) den Enddruck und wird unter Umgehung der Nachverdichtung (C1) einer Weiterverwendung zugeführt. Bei gegenüber dem maximalen Massenstrom reduziertem Massenstrom wird das Gas von der Hauptverdichtung in die Nachverdichtung geleitet, dort auf den Enddruck verdichtet und dann der Weiterverwendung zugeführt. Das zu verdichtende Gas kann bei kryogenen Temperaturen und bei Drücken unterhalb des Umgebungsdruckes vorliegen. Vorzugsweise ist die Hauptverdichtung (C2...C5) mehrstufig ausgeführt und die Nachverdichtung (C1) enthält nur eine Turboverdichterstufe. Die Turboverdichteranlage kann zwischen aufeinanderfolgenden Stufen Zwischenkühler (3) oder Zwischenerhitzer enthalten. Vorteilhafterweise besitzt die Hauptverdichtung, bei mehrstufer Ausführung bevorzugt die erste Turboverdichterstufe, eine Drehzahlregelung. Das zu verdichtende Gas kann Helium sein. Das Verfahren wird bevorzugt in einer Heliumkälteanlage oder Heliumverflüssigungsanlage eingesetzt.

Figure 00000001
The invention relates to a method for compressing a gas with constant pressure, constant temperature and time-varying mass flow to a constant final pressure by dynamic compression with the aid of a turbocompressor system (C 1 ... C 5 ), which is a system for main compression (C 2 .. .C 5 ) and a plant for post-compression (C 1 ) contains. According to the invention, the gas reaches the final pressure at maximum mass flow in the main compression (C 2 ... C 5 ) and is passed on for further use, bypassing the post-compression (C 1 ). If the mass flow is reduced compared to the maximum mass flow, the gas is conducted from the main compression into the post-compression, there compressed to the final pressure and then passed on for further use. The gas to be compressed can be present at cryogenic temperatures and at pressures below ambient pressure. The main compression (C 2 ... C 5 ) is preferably carried out in several stages and the secondary compression (C 1 ) contains only one turbo compressor stage. The turbocompressor system can contain intermediate coolers (3) or intermediate heaters between successive stages. The main compression, in the case of a multi-stage version, preferably the first turbocompressor stage, advantageously has a speed control. The gas to be compressed can be helium. The method is preferably used in a helium refrigeration plant or helium liquefaction plant.
