摘要： An integrated process for simultaneous removal and value addition to sulfur and aromatics compounds of gas oil is disclosed. Refractive sulfur and aromatics compounds of gas oil are segregated in heavy fraction of gas oil using distillation. The refractive sulfur and aromatic compounds rich heavy fraction of gas oil is subjected to continuous solvent extraction zone. The lighter fraction of gas oil and raffinate of heavy fraction of gas oil are subjected to hydrotreating reaction zone operating under mild conditions of temperature and pressure for producing the gas oil with reduced sulfur and aromatic compounds to deep level. The pseudo raffinate from the extract phase of continuous extraction is generated using the water in mixer settler for improving the yield of raffinate by generating the pseudo raffinate which can be used as suitable feed to hydrocracker to generate sulfur free gas oil.
