Patent attributes
An ink carrier oil and water are separated from condensate. One embodiment includes first and second chambers for the separation. The first chamber receives the condensate and has an upper discharge outlet and a lower discharge outlet. The second chamber has an inlet connected to the lower outlet and a second chamber outlet below the upper discharge outlet such that separated carrier oil is discharged through the upper outlet. Separated water is discharged through the second chamber outlet. An interface between the separated carrier oil and water extends between the upper discharge outlet and the lower discharge outlet. In another embodiment, the carrier oil includes at least one of a high molecular weight oil, a lubricating oil and a defoamer. An additive having a lower concentration of the at least one of the high molecular weight oil, the lubricating oil and the defoamer is added to the carrier oil.
