Abstract
Ein Verfahren zur Aufbereitung von Glykol/Wasser-Gemischen aus der Erdgasförderung soll derart weitergebildet werden, dass eine bessere Trennleistung der abzutrennenden Feststoffe erzielbar ist. Dies wird dadurch erreicht, dass das Glykol/Wasser-Gemisch einem ersten Membrantrennprozess unterzogen wird und der Hauptstrom des durch den Membrantrennprozess gewonenenen Konzentrates dem Membrantrennprozess rückgeführt wird und zumindest ein Teilstrom des gewonnenen Konzentrates ausgeschleust wird.A process for the treatment of glycol / water mixtures from natural gas production should be developed in such a way that a better separation efficiency of the solids to be separated can be achieved. This is achieved by subjecting the glycol / water mixture to a first membrane separation process and recycling the main stream of the concentrate obtained by the membrane separation process to the membrane separation process and discharging at least a partial stream of the concentrate obtained.
Description
Die Erfindung betrifft ein Verfahren zur Aufbereitung von Glykol/Wasser-Gemischen aus der Ergasförderung gem. den Merkmalen des Patentanspruchs 1.The The invention relates to a process for the preparation of glycol / water mixtures from the natural gas production gem. the features of claim 1.
Ergas wird bei der Förderung durch Pipelines transportiert. Als Förderhilfsmittel wird unter anderem ein Glykol/Wasser-Gemisch zugegeben, um die Bildung von Hydraten bei der Förderung zu verhindern. Weitere Zusatzstoffe sind sogenannte Korrosionsinhibitoren und Scaleinhibitoren, die zur Verhinderung von Ablagerungen eingesetzt werden. Um die Kosten bei der Erdgasförderung möglichst gering zu halten, ist es ein Ziel, die eingesetzten Förderhilfsmittel sowie Zusatzstoffe wieder zurückzugewinnen. Ein Schritt des Aufbereitungsprozesses bei der Aufbereitung des Glykol/Wasser-Gemisches ist dabei die Abtrennung von Feststoffen, die größer als 0,5 μm im Durchmesser sind. Derartige Feststoffe resultieren beispielsweise aus der Erdgasförderung oder der Korrosion der Pipeline.natural gas will be in the promotion transported through pipelines. As a subsidy is under another a glycol / water mixture added to prevent the formation of hydrates in the promotion. Further Additives are so-called corrosion inhibitors and scale inhibitors, which are used to prevent deposits. To the Cost of natural gas production preferably It is one goal to keep the subsidies used and to recover additives. A step in the preparation process during the preparation of the Glycol / water mixture is the separation of solids greater than 0.5 microns in diameter are. Such solids result, for example, from natural gas production or the corrosion of the pipeline.
Bislang werden diese Feststoffe mittels Zentrifugen und Dekantern abgetrennt.So far These solids are separated by centrifuges and decanters.
Bei der Verwendung von Zentrifugen erfolgt die Abtrennung der Feststoffe in Abhängigkeit des spezifischen Gewichtes. Eine definierte Trenngrenze in Bezug auf eine vorgebbare Teilchengröße kann nicht erzielt werden.at the use of centrifuges, the separation of solids takes place dependent on the specific weight. A defined separation limit in relation to a predeterminable particle size can not be achieved.
Aufgabe der vorliegenden Erfindung ist es, bei der Aufbereitung von Glykol/Wasser-Gemischen aus der Erdgasförderung eine bessere Trennleistung der abzutrennenden Feststoffe zu erzielen.task The present invention is, in the preparation of glycol / water mixtures of natural gas production to achieve a better separation performance of the solids to be separated.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.These The object is achieved by the features specified in claim 1 solved.
Da das aufzubereitende Glykol-Wasser-Gemisch einem Membrantrennprozess unterzogen wird, kann durch gezielte Auswahl der Porengröße der Membran eine definierte Trenngrenze erzielt werden. Eine Abtrennung von Feststoffen der Größenordnung 0,1 – 200 μm kann hierbei erfolgen.There the glycol-water mixture to be treated undergoes a membrane separation process can be subjected by targeted selection of the pore size of the membrane a defined separation limit can be achieved. A separation of Solids of the order of magnitude 0.1-200 μm can be used here respectively.
Gemäß einer Weiterbildung des Erfindungsgedankens erfolgt die Aufbereitung des Glykol-Wasser-Gemisches mit einem zweistufigen Membrantrennprozess, wobei der Hauptstrom des aus dem ersten Membrantrennprozess gewonnenen Konzentrates im Kreislauf geführt wird und ein Teilstrom des gewonnenen Konzentrates einem zweiten nachgeschalteten Membrantrennprozess unterzogen wird. Hierdurch wird eine Recyclingrate größer 95% erreicht.According to one Further development of the concept of the invention, the preparation of the Glycol-water mixture with a two-stage membrane separation process, wherein the main stream of the recovered from the first membrane separation process Concentrate in circulation and a partial flow of the recovered concentrate a second downstream membrane separation process is subjected. hereby is a recycling rate greater than 95% reached.
