ABSTRACT:
Process and apparatus are provided for blending a fuel which includes a No. 2 fuel oil component and a No. 1 fuel oil component, with the No. 1 fuel oil component being added to provide a fuel mixture which will not freeze or form solid wax particles above a predetermined temperature. The process includes lowering a temperature of a sample of the No. 2 fuel oil component, detecting a change in wax crystal concentration of the No. 2 fuel oil component sample by detecting a predetermined rate of change in viscosity of the sample or by detecting a predetermined viscosity level of the sample as the temperature thereof is lowered, and measuring a temperature of the No. 2 fuel oil component or bath in which it is cooled, when the change in wax crystal concentration is detected. A percentage amount of the No. 1 fuel oil component to be mixed with the No. 2 fuel oil component is determined based on the temperature measured as above and on stored data representing respective amounts of the fuels to be mixed to obtain a blend which will not freeze or form solid wax particles above respective fluidity control temperatures. A signal representing this percentage amount is fed to a blending unit which automatically blends the No. 1 and No. 2 fuel oil components in accordance with this determined percentage amount.
