ABSTRACT:
A process for separating petroleum distillation residues into a lower boiling fraction and a higher boiling fraction. The separation is effected with the aid of a process gas under super-critical conditions of temperature and pressure such that the gas selectively takes up the lower boiling fraction. By suitable selection of the gas, the process can be carried out at relatively low temperature, and with low input energy requirements when performed with recycling of the process gas.
