摘要:
A computer implemented blend control system and method for preparation of a hydrocarbon blend from a plurality of component streams have been disclosed. The system includes a product tank for receiving a mixture comprising the plurality of component streams. The system further includes a sensor and analyzer adapted to sense and analyze a first attribute of the received mixture for obtaining a first attribute data. The system further includes an optimizer which stores the attribute based model data, receives the first attribute data and compares the received first attribute data with the attribute based model data to compute an optimized proportion data, based on which the component streams are selectively drawn into the product tank for preparing the hydrocarbon blend.

A computer implemented blend control system and method for preparation of a hydrocarbon blend from a plurality of components drawn from respective component tanks have been disclosed. The system, in accordance with the present disclosure includes at least one sensor and analyzer adapted to sense and analyze a first attribute of at least one of the components for obtaining first attribute data. The system further includes, at least one optimizer having a data storage means for storing attribute based model data. The optimizer receives the first attribute data and transmits the received first attribute data to a comparator which computes an optimized proportion data between each of the component streams to enable selective drawing of each of the component streams in accordance with the optimized proportion data for preparing the hydrocarbon blend.
摘要:
A process for catalytic conversion of low value hydrocarbon streams to light olefins in comparatively higher yields is disclosed. Propylene is obtained in amounts higher than 20 wt. % and ethylene higher than 6 wt. %. The process is carried out in a preheated cracking reactor having a single riser and circulating an FCC catalyst. The riser is divided into three temperature zones in which different hydrocarbon feeds are introduced. An oxygenate feed is introduced in the operative top zone in the riser. Heat for the endothermic cracking is obtained by the exothermic reaction of converting the oxygenate feed into gas and/or from a regenerator in which the spent FCC catalyst is burnt.

A process for obtaining vanadium component in the form of vanadium oxide from gasifier slag is disclosed. The process comprises pulverizing the slag to obtain pulverized slag, which is blended with water and an alkali salt to obtain a slurry. The slurry is dried and then roasted in the presence of air to obtain a roasted slag. The roasted slag is leached to obtain a first filtrate comprising the vanadium component. The first filtrate is reacted with a magnesium salt to remove a silica component in the form of a precipitate. The silica free second filtrate is reacted with an ammonium salt to obtain ammonium metavanadate, which is further calcined to obtain the significant amount of vanadium pentoxide (V2O5).
摘要:
The present invention relates to a catalyst composition for Fluid Catalytic Cracking (FCC) which contains a combination of a FCC catalyst component and an additive component with certain physical properties attributed therein. The present invention is also directed to provide methods for the preparation of the catalyst composition for FCC. The admixture of the FCC catalyst component and additive component is used in cracking of hydrocarbon feedstock containing hydrocarbons of higher molecular weight and higher boiling point and/or olefin gasoline naphtha feedstock for producing lower yield of fuel gas without affecting the conversion and yield of general cracking products such as gasoline, propylene and C4 olefins.
