Abstract: An aspect of the present disclosure relates to a process for solvent deasphalting dearomatization, said process including: effecting deasphaltenation of a heavy oil feed by contacting the feed with a paraffinic rich solvent, optionally, in presence of a FCC catalyst to obtain a deasphalted oil rich stream, said paraffinic rich solvent being untreated naphtha; contacting the DAO rich stream with a second solvent to obtain a raffinate stream rich in non-asphaltene and non-aromatic contents and a solvent rich stream; contacting the raffinate stream with water in a first decanter to obtain a first stream rich in aromatic-lean fraction and a second stream rich in the second solvent and water; subjecting the first stream to distillation to recover the paraffinic rich solvent and to obtain deasphalted oil; contacting the solvent rich stream with water in a second decanter to obtain an aromatic rich fraction and a third stream rich in the second solvent and water; and subjecting the second stream and the third stream

Abstract: A method for inhibiting corrosion on internal metal surfaces of an overhead condenser of a crude distillation unit in which hydrocarbons, water and amine hydrochlorides condense, the method includes adding to the overhead condenser an amine composition in an amount and at a rate sufficient to maintain the pH of water condensate in the condenser above a pH of about 5, the amine composition made of a mixture of four amines wherein the amines are monoethanloamine, methoxypropyl amine, morpholine and cyclohexylamine present in a weight ratio ranging from about 25:30:25:20 to about 30:40:15:15. Further, a system and method assess the corrosion rate and optimize the dosage of neutralizing amine composition during the operating conditions of overhead condensing system.

Abstract: A method for modification of pretreated acidic porous material via selective cation exchange using suitable solvent to obtain higher noble metal dispersion is described herein. The solvent system required for cation exchange should have its dielectric constant in the range of 25-45, wherein this solvent property is found to impart significant effect on cation loading and distribution, which in turn defines the stability, dispersion of the noble metals. The catalyst so obtained has higher noble metal dispersion and when used for hydroisomerization reaction, leads to higher selectivity even at significantly high conversion values.

Abstract: Method(s) and a system for predicting the refining characteristics of an oil sample are described. The method of predicting the refining characteristics, such as distillate yield profile, processability, product quality or refinery processing cost, may include development of a prediction model based on regression analysis. The method may further include determining the physical properties of the oil sample and predicting the refining characteristics based on the developed prediction model. The determination of the physical properties of the oil sample includes determining at least one of Conradson Carbon Residue (CCR) content, Ramsbottom Carbon Residue (RCR) and Micro Carbon Residue (MCR).

Abstract: The present invention relates to a process for the synthesis of ATO molecular sieve framework comprising forming a reaction medium comprising of reactive sources Al2O3, P2O5 and /or silica and a templating agent and subjecting the reaction medium to microwave hydrothermal heating until crystals of ATO framework are formed. The templating agent used in the reaction medium is a long chain quaternary ammonium dihydroxide organic moiety having C5-C10 linear chain alkane, alkene or alkyl. The crystalline ATO type molecular sieve framework obtained by the process of the present invention is pure and completely free from commonly observed major impurity phase, namely AEL framework.
