Title: Treatment of petroleum waste oil containing water
Inventor: OKAZAKI HIROSHI
IPC: B01D17/04
Filed: 1978-09-29
Abstract: PURPOSE: To separate easily oil by a method such as settling or centrifugal separation by adding oil containing more than a specified proportion of aromatic hydrocarbons to petroleum waste oil containing water, sludge, etc.  
     CONSTITUTION: Aromatic hydrocarbon oil containing more than 50% by weight, preferably 70% by weight of aromatic hydrocarbons of residual oil obtained by distilling a distillate within the range of from for light oil to xylene, is added to water-in-oil type petroleum waste oil containing water and sludge as solid resulting from oil tank washing step to mix, whereby W/O emulsion is broken, sludge settles and the separation of oil from water becomes easy. Then oil, water and solids can be separated by a method such as settling or centrifugal separation. Waste oil containing water can be separated without using much energy source and the recovered oil can be used as fuel.

Abstract: PURPOSE:To make it possible to perform heat exchange excellent in efficiency by a wide heat transfer area between fluids by dividing a honey-comb formed body into two or more sections, that is, an outer peripheral part, a central part and the like to form passages, supplying a high-temperature fluid to at least on passage, and also supplying a low-temperature fluid to a passage contiguous to the passage for the high-temperature thereby to carry out heat-exchange. CONSTITUTION:In a honey-comb heat exchanger 1, a columnar honey-comb formed body 10 made of silicon carbide is divided into two parts, that is, an outer peripheral part and an intermediate cylinder 12 to form an external passage 11 and an internal passage 13. A high-temperature fluid H such as a combustion gas or the like is supplied to the internal passage 13, and a low- temperature fluid C such as air for space cooling or the like is supplied to the external passage 11 continuous to the internal passage 13 for the high- temperature fluid so that both fluid are in the counterflow relationship to effect the heat-exchange. Since a rotary driving device such as a rotary type heat exchanger is not required, the structure becomes simple and the cost therefor is markedly reduced.
