Abstract

The authors report on their study of the intensification of the process of vacuum distillation of atmospheric resids with the aim of increasing the yield of vacuum distillates, which are used as cat cracker feed and in lube oil production. Charts present data on hydraulic resistance of the heater coil as a function of additive concentration, and a table presents the data gathered on different resids and activating additives. The authors conclude that with optimum concentrations of the activating additives, the lowest hydraulic resistance of the coil is achieved, along with a maximum increase in the yield of the vacuum distillate.
