USE OF A GRAVITY TYPE OIL SEPARATOR FOR TANKER OPERATIONS

In order to meet the IMCO Amendments to the International Convention for the Prevention of the Pollution of the Sea by Oil, Cities Service Tankers Corp. and Cities Service Oil Co. have been experimenting with various ways of separating oil from ballast water so that the clean ballast water can be discharged without violating the convention. It was found that a gravity type separator is the best type for marine use. The SEREP T-24 separator which Cities Service has been testing is described in the article. It uses mechanical means to separate the oil and water, discharging the water overboard and discharging the reclaimed oil into a slop tank. Approximately 1,200 to 1,500 barrels of burnable slop oil has been recovered per trip from ballasting and cleaning operations. The separator discharges an average of 2.6 litres of oil per mile and 7.8 barrels of oil per voyage with the discharged water, which is well inside the IMCO Amendments. The article concludes that, except for heavy crudes and heavy No. 6 oils, the T-24 is an efficient oily water separator.
