  • Publication number: 20130270155
    Abstract: The present invention relates to a novel process for desulfurization of diesel with reduced hydrogen consumption. More particularly the subject invention pertains to an integrated process comprising diesel hydro de-sulfurisation (DHDS) or diesel hydrotreatment (DHDT) with reduced severity to desulfurize high sulfur (1.0-2.0 wt %) diesel stream to a much lower level of sulfur content of 350-500 ppm in the depleted diesel stream, followed by a novel adsorption procedure for effecting deep desulfurization to reduce overall sulfur content to less than 10 ppm with reduced hydrogen consumption, as compared to high severity DHDS or DHDT procedures of the prior art.

  • Publication number: 20130240405
    Abstract: The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70° C.), Intermediate Cut (70-90° C.) and Heavy Cut (90-210° C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurised by caustic treatment using CFC along with Light cut or separately desulfurised before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process.

  • Publication number: 20130197251
    Abstract: The invention describes process for demetallation of vegetable oils and animal fats to reduce metal content below 1 ppm to make them suitable for hydroprocessing feedstocks. The process comprises acid treatment with very low concentration of acids, utilizing synergistic effect of phosphoric acid and citric acid, followed by counter-current treatment with clay without intermediate step of water washing and treatment with ion exchange resin.

  • Publication number: 20120259637
    Abstract: An electronic apparatus and method for retrieving a song, and a storage medium. The electronic apparatus includes: a storage unit which stores a plurality of songs; a user input unit which receives a hummed query which is inputted for retrieving a song; and a song retrieving unit which retrieves a song based on the hummed query from among the plurality of stored songs when the hummed query is received. The song retrieving unit extracts a pitch and a duration of the hummed query, converts each of the extracted pitch and duration into multi-level symbols, calculates a string edit distance between the hummed query and one of the plurality of songs based on the symbols, and determines a similarity between the hummed query and a song based on edit operations which are performed within the calculated string edit distance.

  • Patent number: 8222180
    Abstract: The present invention relates to a adsorbent composition for removing refractory sulphur compounds from refinery streams comprising of base component in the range of 10 to 50 wt %, spinel oxide in the range of 20 to 60 wt % as a reactive metal oxide component and bimetallic alloy in the range of 10 to 40 wt % acting as an adsorption enhancer component, wherein the adsorption enhancer component acts in synergy with base component. The invention also relates to a process for the preparation of said composition by mixing in solid state fine particles of base component, spinel oxide and bimetallic alloy, homogenizing the mixture thus obtained with solvent, peptizing the wet solid with dilute mineral acid, extruding the peptized material with extrusion aiding agents, drying the extrudates, further calcining the dried extrudates and reducing the calcined material under hydrogen flow.

  • Patent number: 7207445
    Abstract: An apparatus for separating impurities from a liquid by a non-dispersive contacting of a liquid—liquid reactive systems, the liquids being immiscible with each other, having a cylindrical column separated into a first stage and a second stage, a plurality of modules of packed metallic fibers mounted in the first stage of the column on a support, a first distributor provided in the first stage of the column for distributing a first liquid located above the support such that the first liquid completely wets the fibers by capillary action and forms a film thereon, a second distributor fitted at a bottom portion of the second stage for distributing a second liquid containing impurities on to the metallic fibers, wherein the second liquid flows concurrently with said first liquid so that the impurities present in the second liquid react with the first liquid and dissolve therein and a separator connected to a bottom of said column separates the first liquid and purified second liquid.
