Intensification of the Bitumen Production Process

The intensification and automation of deasphalting units with propane is considered from the point of view of the possibility of obtaining deasphalting asphalt, which is stable in physical and chemical properties, in particular, in terms of softening and flash points. The use of deasphalting asphalt as a component of compounded bitumen or as a raw material for the production of oxidized bitumen imposes certain requirements on the stability of its (asphalt) properties. On the basis of the research carried out by the authors and the analysis of the operation of existing installations, the following schemes of automatic control and regulation of the main units of the process of deasphalting with propane have been proposed [1,2: 45-46, 61].
