ABSTRACT:
The undesirable and damaging reaction heat occurring during the blowing of asphalt is avoided by injecting water into the air inlet pipes of the reactor vessel heated by the hot asphalt surrounding them. During this, the superheated steam produced without expenditure is passed through the liquid asphalt, causing the removal of low molecular hydrocarbons formed during the blowing or stripping.
