Ejector Applications

Crude oil distillation

Motor gas and lube oil refineries have a number of applications for ejector systems. Crude vacuum distillation, lube oil distillation, vacuum flasher, and gas oil hydrodesulphurization are the typical applications. Graham ejector systems support the majority of refinery vacuum distillation applications throughout the world. We have computer simulation programs that accurately model vacuum tower overhead hydrocarbons and we have specialized condenser designs for handling mixtures of miscible hydrocarbons and steam in the presence of large volumes of noncondensible gases. Our vacuum condenser design supports the ejector systems by providing accurate simulation of vapor/liquid equilibrium, optimal condensation efficiency, and minimal pressure loss across the condenser.
