Abstract

In this study, the deep desulfurization of DBT (Dibenzothiophene) from simulated fuel (200 ppm) was investigated using a microfluidic system by DES (Deep eutectic solvent). The experiments were done based on a previous work, which indicated that velocity of 0.2 m/s and volume ratio of 1:1 give the highest sulfur removal (E%). The equilibrium extraction stages needed to achieve an overall sulfur removal below 15 ppm was studied for channels with different lengths of 10, 30 and 50 cm. In general, it was found that two equilibrium stages are needed to reach deep desulfurization for all three lengths. However, the number of cycles within a single stage differed according to the channel length used. These cycles are reduced with rising the length of the channel. The overall volumetric mass transfer coefficient (KLa) was calculated for three cycles in each of the three lengths. It was found that KLa decreases with increasing the residence time (channel length).
