Problems solved by technology

[0007] However, the currently used membrane filters still carry the risk of clogging the membrane filter, which is particularly undesirable in the context of offshore hydrocarbon production or even in subsea media, and it is desirable to limit as much as possible the use for maintenance or Operation of replacing the membrane filter

Embodiment Construction

[0062] The invention is now described in a more specific and non-limiting manner in the following specification.

[0063] Tangential filter circuit according to the invention

[0064] refer to image 3 , which first describes the coupling of membrane filtration to the purification of the retentate before subsequent recirculation, wherein a tangential membrane filtration loop inside a membrane filtration unit used within the scope of the invention is shown.

[0065] The circuit comprises a water receiving line 29 on which a circulation pump 21 is arranged. The water receiving line 29 leads into one or more membrane filtration modules 22, 23 positioned in series and / or in parallel, preferably in parallel. In the illustrated embodiment, two parallel positioned membrane filtration modules 22, 23 are provided.

[0066] "Membrane filtration module" refers to an individual membrane filtration element comprising a membrane filter.

[0067] A line 25 for collecting permeate is co...

Abstract

A water treatment method includes: filtering water in a membrane filtration unit including at least one membrane filtration module; collecting a permeate and collecting a retentate at the outlet of the membrane filtration module; withdrawing solid materials and / or hydrocarbons contained in the retentate, in order to provide a treated retentate; recycling the treated retentate at the inlet of the membrane filtration module; providing a treated water flow from the permeate from membrane filtration module(s). An installation adapted for applying this method is also provided.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of October 11, 2011, an application number of "201180054792.5", and an invention title of "Water Treatment in At Least One Membrane Filtration Unit for Facilitating Hydrocarbon Recovery". technical field [0002] The present invention relates to a method for treating water in the context of hydrocarbon production, more particularly in the context of facilitating oil recovery, and to a device suitable for applying the method. Background technique [0003] In the field of hydrocarbon production, operations for recovering hydrocarbons by the natural pressure of hydrocarbon-bearing subterranean formations (so-called "primary" recovery) are usually followed by so-called "secondary" recovery by injecting water. [0004] In this context, water generally needs to be treated before it is injected into a subterranean formation in order to remove most of the contaminants it may c...
