Abstract

The middle distillate yield from visbreaking plants is increased by measuring the tar stability at the outlet of the fractionating column, adding a tar-stabilising additive (I), measuring the tar stability again, and increasing the furnace temp. (and thus the middle distillate yield) until the tar stability drops to its initial value. (I) is a soln. contg. 5-60wt.% of an alkylsuccinimide (II), 0-30wt.% phenolic or amine antioxidants and 0-5wt.% metal deactivators. (II) has an N content of 1-8% and a total basicity of 20-200 mg KOH/g, and may also contain B and P. Cpds. (II) are described in DE2053800, GB960493, GB1186659 and US3172892.
