Abstract: An integrated process for simultaneous removal and value addition to sulfur and aromatics compounds of gas oil is provided. Process includes the segregation of refractive sulfur and aromatics compounds of gas oil in heavy fraction of gas oil using distillation processing of heavy fraction of gas oil in continuous solvent extraction zone, processing of lighter fraction of gas oil and raffinate of heavy fraction of gas oil in hydrotreating reaction zone operating under mild conditions of temperature and pressure for producing the gas oil with reduced sulfur and aromatic compounds and contact of extract phase generated during continuous extraction with water in mixer settler for generating the pseudo raffinate which can be used as suitable feed to hydrocracker to generate sulfur lean gas oil.

Abstract: 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.

Abstract: Disclosed is a process for production of benzene lean gasoline by recovery of high purity benzene from a narrow boiling benzene concentrated unprocessed cracked gasoline fraction. The process involves subjecting the feed material to an extractive distillation (ED) operation using an aromatic selective solvent in combination with a co-solvent.

Abstract: A method (and structure) of querying one or more Web-based data sources, includes receiving a query statement including at least one query, parsing the input query to identify a target data source for each query, and dispatching each query to a respective one of the data sources for a target data source search. The query statement further includes an aggregate operator defining at least one logical operation to be performed on a result returned from the target data source searches.
