Abstract
Visbreaking experiments on Quyarah long residue have been conducted in a continuous laboratory-scale visbreaking unit at different temperatures from 435°C to 490°C at one pressure (7 bar) and constant residence time (90 sec.). Data on yield of different products have been reported. Further, thermal cracking experiments on visbroken vacuum gas oil under relatively high severity were also given in the same unit in order to reduce the residual yield of Quyarah crude.Keywords
