Abstract
The physical structure of asphaltene dispersion in crude oil is important from the point of view of refining technology and can subject to modification, for example, using an aromatic component, such as pyrolysis oil. The lab results were verified in industrial tests in the atmospheric-vacuum distillation (AVD) process of crude oil. Positive test results made it possible to use pyrolysis oil on an industrial scale as the component, favorably changing crude oil’s dispersion structure and properties. The implementation of a new method of distillation of crude oil partially confirmed the expected effects and revealed new aspects of technology modification. In the course of research on this type of petroleum dispersion, carried out for the refining industry, several patented solutions have been developed, some of which have been successfully applied in the industry.
