Abstract
The quality of a hydrocarbon oil is controlled during its manufacture or blending by periodically suspending a drop of the oil being produced in a stream of hot inert gas, the temperature and rate of flow of which is substantially constant, and <PICT:0769751/III/1> determining the change in size of the drop, or a parameter thereof, with time and, if and when necessary, adjusting one or more of the conditions of the process of manufacture or blending to maintain said change between predetermined limits. The hydrocarbon oil may be a lubricating oil, particularly one for use in a steam engine or steam turbine, but hydrocarbon materials, for example waxes and bitumens, which become molten at elevated temperatures are also applicable. The inert gas may be nitrogen, carbon dioxide or superheated steam. The change in size of the suspended drop with time is preferably determined by determining the volume of the droplet (or a parameter thereof such as the volume of a magnified optical image of the drop) from time to time during the course of the test, and expressing the results as a percentage of the volume of the drop at the commencement of the test. In the apparatus for conducting the test shown in Fig. 1, a drop of the oil 8 is suspended by a glass fibre and a beam of light from lamp 37 passes through lens system 38, thereby projecting a magnified image of the drop on the screen 39. A jet of steam from orifice 31 is directed on to the oil drop. The steam is produced in boiler 5, which is supplied with water from tank 17, and is superheated in tube 6 provided with electric heater 27. A diffuser containing, for example, six wire mesh grids 30 serves to stabilize the temperature and flow characteristics of the superheated steam. In the examples, (a) the preparation of a lubricating oil by solvent extraction of a crude petroleum according to the Duo-Sol process is carried out to obtain a product of desired evaporation characteristics and (b) the preparation of a blend of mineral lubricating oil and bright stock is carried out to obtain a product of desired evaporation characteristics.
