Abstract

1417028 Drying and degassing oil B O C INTERNATIONAL 21 Nov 1973 [22 Nov 1972] 53956/72 Headings BIB and B1M [Also in Division H5] A liquid such as transformer oil containing impurities is dried and degassed by passing the oil from conduit 34 into the permeable Joula heater 26 and passes out into the filled column 10 where it flows in a thin film to the filter 36 and outlet 14. The chamber 2 is maintained under vacuum by pump 20. The oil flows to the reservoir 38 and can be recycled until the oil is sufficiently purified.
