Abstract
Description
Die Erfindung betrifft eine Druckerhöhungsanlage nach dem Oberbegriff des Patentanspruchs 1 sowie ein entsprechendes Verfahren zum Betreiben einer Druckerhöhungsanlage.The invention relates to a pressure booster system according to the preamble of patent claim 1 and a corresponding method for operating a pressure booster system.
Technische Fluide, welche für verschiedenste Prozesse benötigt werden, werden typischerweise in flüssiger Form unter relativ niedrigem Druck, in der Regel leicht über Atmosphärendruck, angeliefert. Hier sei beispielsweise die Anlieferung von flüssigem Stickstoff, Sauerstoff, Argon, Helium oder Wasserstoff genannt, wobei diese Fluide für zahlreiche Anwendungen in gasförmiger Form bereitgestellt werden müssen. In der Regel werden höhere Prozessdrücke z. B. von etwa 3–5 bar benötigt, welche durch Lieferbehälter, welche in der Regel niedrige Betriebsdrücke aufweisen, nicht bereitgestellt werden können. Als typische Lieferbehälter seien hier beispielhaft Tankfahrzeuge bzw. ISO-Container genannt.Industrial fluids required for a variety of processes are typically supplied in liquid form under relatively low pressure, usually slightly above atmospheric pressure. Here, for example, the delivery of liquid nitrogen, oxygen, argon, helium or hydrogen may be mentioned, these fluids must be provided for numerous applications in gaseous form. In general, higher process pressures z. B. of about 3-5 bar required, which can not be provided by delivery containers, which usually have low operating pressures. As typical delivery containers, tank vehicles or ISO containers are mentioned here by way of example.
Eine übliche Methode zur Druckerhöhung ist die Verwendung von sogenannten Druckerhöhungssystemen. Diese Systeme weisen prinzipiell wenigstens zwei thermisch isolierte Aufnahmebehälter und einen Pufferbehälter bzw. Pufferspeicher auf. Im Wechsel werden diese isolierten Behälter mit Flüssigkeit bzw. flüssigem Prozessfluid aus dem Anlieferfahrzeug bis zu einem bestimmten Füllstand befüllt. Anschließend wird der jeweils befüllte Behälter geschlossen und mit Druck beaufschlagt, der über dem erforderlichen Prozessdruck liegt. Schließlich wird der so druckbeaufschlagte Behälter zu dem Pufferspeicher hin geöffnet, womit dieser nachgefüllt wird. Der Prozess wird sodann aus diesem als Speicher dienenden Pufferspeicher versorgt. Zwischen die Aufnahmebehälter und den Pufferspeicher ist hierbei eine Verdampfereinrichtung geschaltet.A common way to increase the pressure is the use of so-called pressure booster systems. These systems have in principle at least two thermally insulated receptacle and a buffer tank or buffer memory. Alternately, these insulated containers are filled with liquid or liquid process fluid from the delivery vehicle up to a certain fill level. Subsequently, each filled container is closed and pressurized, which is above the required process pressure. Finally, the thus pressurized container is opened to the buffer memory, so that this is refilled. The process is then supplied from this memory buffer. Between the receiving container and the buffer memory in this case an evaporator device is connected.
Nachteilig an der oben beschriebenen Vorgehensweise ist, dass sie verlustbehaftet ist. Nach Herstellung eines Druckausgleichs zwischen dem jeweils druckbeaufschlagten Aufnahmebehälter und dem Pufferspeicher muss der Behälter wieder in einen Zustand gebracht werden, in dem er erneut Flüssigkeit bzw. flüssiges Prozessfluid aus dem Lieferbehälter (Lieferfahrzeug) aufnehmen kann. Dies geschieht herkömmlicherweise durch das Ablassen des gegenüber der Umgebung noch herrschenden Überdrucks, wobei das hierbei entweichende Gas, welches im Wesentlichen gasförmiges Prozessfluid umfasst, verloren geht.A disadvantage of the procedure described above is that it is lossy. After establishing a pressure equalization between the respectively pressurized receiving container and the buffer memory, the container must be brought back into a state in which it can again receive liquid or liquid process fluid from the delivery container (delivery vehicle). This conventionally takes place by discharging the overpressure which still prevails with respect to the environment, whereby the gas escaping in the process, which comprises essentially gaseous process fluid, is lost.
Aufgabe der Erfindung ist die Bereitstellung einer effektiven Druckerhöhung, bei der derartige Verluste vermieden werden können.The object of the invention is to provide an effective pressure increase, in which such losses can be avoided.
Diese Aufgabe wird gelöst durch eine Druckerhöhungsanlage mit den Merkmalen des Patentanspruchs 1. Diese Aufgabe wird ebenfalls gelöst durch ein Verfahren mit den Merkmalen des Patentanspruchs 6.This object is achieved by a pressure booster with the features of claim 1. This object is also achieved by a method having the features of
Mittels der erfindungsgemäßen Einbringung eines Ejektors bzw. Gasstrahl-Kompressors in die Zuleitung, welche den Pufferspeicher mit der eigentlichen Prozessanlage verbindet, kann eine besonders effektive und im Wesentlichen verlustfreie Druckerhöhung zur Verfügung gestellt werden, da hiermit in einem mit der Saugseite des Ejektors verbundenen Saugpuffer ein Unterdruck erzeugt werden kann. Das in einem Aufnahmebehälter nach Druckausgleich mit dem Pufferspeicher verbleibende gasförmige Prozessfluid kann somit erfindungsgemäß in den Saugpuffer abgelassen werden, und dem Prozess anschließend zugeführt werden. Die erfindungsgemäße Lösung erweist sich gegenüber herkömmlichen Systemen als preiswert bereitstellbar und wartungsarm.By means of the inventive introduction of an ejector or gas jet compressor in the supply line, which connects the buffer memory with the actual process plant, a particularly effective and substantially loss-free pressure increase can be made available, since hereby in a connected to the suction side of the ejector suction buffer Negative pressure can be generated. The remaining in a receptacle after pressure equalization with the buffer storage gaseous process fluid can thus be discharged according to the invention in the suction buffer, and then fed to the process. The solution according to the invention proves inexpensive and low-maintenance compared to conventional systems.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Es ist besonders vorteilhaft, wenigstens zwei Aufnahmebehälter vorzusehen, welche wahlweise bzw. abwechselnd mit dem Pufferspeicher und/oder dem Saugpuffer (über entsprechende Verbindungsleitungen) in Verbindung bringbar sind. Mit wenigstens zwei Aufnahmebehältern ist eine kontinuierliche und zuverlässige Versorgung des Pufferspeichers mit gasförmigem Prozessfluid bereitstellbar.It is particularly advantageous to provide at least two receiving containers which can be brought into contact with the buffer store and / or the suction buffer (via corresponding connecting lines) selectively or alternately. With at least two receptacles a continuous and reliable supply of the buffer storage with gaseous process fluid can be provided.
Vorteilhafterweise sind zur Bereitstellung sowie zur Unterbrechung einer Verbindung zwischen dem wenigstens einen Aufnahmebehälter und dem Pufferspeicher und/oder zwischen dem wenigstens einen Aufnahmebehälter und dem Saugpuffer mit Absperrventilen ausgebildete Verbindungsleitungen vorgesehen. Derartige Absperrventile sind in einfacher Weise im Rahmen eines automatisierten Verfahrens programmierbar, um eine zuverlässige und kontinuierliche Versorgung des Pufferspeichers bzw. des Prozesses mit gasförmigen Prozessfluid zu gewährleisten.Advantageously, connecting lines are provided for providing and interrupting a connection between the at least one receptacle and the buffer reservoir and / or between the at least one receptacle and the suction buffer with shut-off valves. Such shut-off valves can be programmed in a simple manner as part of an automated process in order to ensure a reliable and continuous supply of the buffer storage or of the process with gaseous process fluid.
Es ist bevorzugt, die Aufnahmebehälter als thermisch isolierte Behälter auszubilden.It is preferable to form the receptacles as thermally insulated containers.
Besonders bevorzugt ist ferner, die Einrichtung zur Druckbeaufschlagung als Einrichtung zur Beaufschlagung des flüssigen Prozessfluids mit gasförmigen Prozessfluid auszubilden. Mit dieser Maßnahme kann der in den Aufnahmebehältern herrschende Druck in einfacher Weise ohne Kontaminierung des Prozessfluids erhöht werden, um anschließend das so druckbeaufschlagte Prozessfluid dem Verdampfer und dem Speicherpuffer zuzuführen. Insgesamt muss hierbei nur ein kleiner Bruchteil des Prozessfluids in gasförmigem Zustand der Druckerhöhungsanlage zugeführt werden. Der Großteil des Prozessfluids kann in flüssiger Form bereitgestellt werden, was wesentlich preiswerter und unaufwändiger ist.It is also particularly preferred to form the device for pressurizing as a device for acting upon the liquid process fluid with gaseous process fluid. With this measure, the pressure prevailing in the receptacles pressure can be increased in a simple manner without contamination of the process fluid to then supply the thus pressurized process fluid to the evaporator and the storage buffer. All in all, only a small fraction of the process fluid in the gaseous state has to be used Pressure booster system to be supplied. Most of the process fluid can be provided in liquid form, which is much cheaper and less expensive.
