Abstract

An air-cooled distillation unit has been designed for operation in the severe climate of Siberia and the Tyumen Oblast for purposes of satisfying regional fuel requirements. The feed is a mixture of desalinated condensate and oil fringe from the Urengoi field. It is initially heated in exchangers using the heat of the circulating reflux and product cuts leaving the distillation tower and then is further heated in a furnace from which it passes into a vaporizer designed to remove most of the naphtha cut. The liquid phase is then separated in the tower into cuts of naphtha, kerosene, diesel fuel and boiler fuel. The naphtha cuts are redistilled to obtain a jet engine fuel base. Production yields are cited for these fuels as well as for gasoline. Process control is automated.
