Embodiment Construction

[0012] The compressor system diagrammatically illustrated in Figure 1 is intended to supply compressed air to, for example, a plurality of machines driven by compressed air. The system comprises an inlet channel 10 through which air is drawn into a compressor 12 which supplies compressed air to an outlet channel 14 . During operation, a large amount of water condenses in the compressor 12 and this condensate flows under pressure through the flow line 16 to a small holding tank 18 . The condensate may include water and some oil emulsified in the water, which must be removed from the condensate residue prior to disposal of the condensate as previously stated.

[0013] To separate the oil from the condensate residue, the contents of holding tank 18 are regularly supplied to separator 22 by means of a pump (not shown) and flow line 20 . The supply of condensate from the holding tank 18 to the separator 22 may occur at regular intervals, the pump being controlled by a timer. Alte...

Abstract

A device used to separate oil from compressor condensate. It comprises a separator having an upper chamber provided with a condensate inlet and a filter housing containing a hydrophobic and oleophilic substance so that in use condensate flows from the upper chamber through said filter housing under the influence of gravity body. The upper chamber houses a coalescing filter connected to the condensate inlet. In an alternative arrangement, the holding tank is in series with the separator and means are provided for supplying the condensate in the holding tank with a demulsifier prior to supplying the condensate to the separator. The apparatus described above may perform a method comprising the steps of mixing condensate with a demulsifier, maintaining the mixture to at least partially crack the emulsion, and supplying the at least partially cracked emulsion to a separator containing a hydrophobic-oleophilic substance.

Description

technical field [0001] This invention relates to separators, in particular separators for removing oil from condensate produced by air compressors. Background technique [0002] Condensate produced during air compressor operation is often contaminated with oil, such as compressor lubricating oil. The presence of contamination makes condensate disposal difficult. It is therefore desirable to be able to separate the oil from the condensate, and one way to do this is to store the condensate in large reservoirs long enough to separate the oil from the condensate by virtue of the different densities. However, this technique has the disadvantage that, where large amounts of condensate are generated, the storage must have a large capacity and occupy a large area of ​​floor space. [0003] GB-B-2355942 discloses a separator for separating oil from condensate produced during compressor operation, the separator comprising a reservoir and a filter housing containing a hydrophobic and...
