Main Points Analysis of Semiasphalt Visbreaking desigh

This paper expounds the technical principles to design industrial semiasphalt visbreaking equipments, introduces the bese and methods to determine some critical technical parameters such as "flow velocity of coolant oil for heating furnace tube", "reaction time", and "quench oil quality and the control methods".Production practice in several years show that all the indexes reach or override the desigh indexes, and notable economic and social benefits havc been achieved.
