Low Aromatic Solvents Through Dearomatization on Molecular Sieve 13X

Abstract

The possibility of preparing low aromatic solvents by passing some of refinery streams over molecular sieve 13X has been studied. From experimental data dynamic and equilibrium capacity were calculated and S-curves constructed and used to calculate the height of mass transfer zone and height of unused mass transfer zone. Laboratory experiments data gave us optimal temperature and liquid velocity for each crude oil fraction at which the height of mass transfer zone had the lowest value. The correlation of zone height and linear liquid velocity for gasoline, white spirit and kerosene was found.
