The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (KCO) is impregnated thereon to form an adsorbent comprising potassium carbonate (KCO) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.

Process for capturing carbon-dioxide from a gas stream

The present invention provides a process for recovery of propylene and LPG from the fuel gas produced in FCC unit by contacting a heavier hydrocarbon feed with FCC catalyst. The process provides an energy efficient configuration for revamping an existing unit constrained on wet gas compressor capacity or for designing a new gas concentration unit to recover propylene and LPG recovery beyond 97 mole %. The process of the present invention provides an increase propylene and LPG recovery without loading wet gas compressor with marginal increase in liquid loads.

The present disclosure provides a single compression system and a process for capturing carbon dioxide (CO) from a flue gas stream containing CO. The disclosure also provides a process for regeneration of the carbon dioxide capture media.

Single compression system and process for capturing carbon dioxide

A method for removing chloride impurities from a heavy hydrocarbon stream is disclosed. The heavy hydrocarbon stream is contacted with a stripping medium at a temperature ranging between 100-450&#xb0; C. and at a pressure ranging between 0.1-2 bar with ratio of the heavy hydrocarbon stream to the stripping medium ranging between 1-30; wherein the temperature is maintained below the initial boiling point of the hydrocarbon stream.

The present disclosure provides a multiple-compression system and a process for capturing carbon dioxide (CO) from a flue gas stream containing CO. The disclosure also provides a process for regeneration of the carbon dioxide capture media.

Multi-compression system and process for capturing carbon dioxide

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.

Afatinib salts and crystalline forms thereof are described in the present application and processes for their preparation. Crystalline forms of Afatinib are also described in the present application and processes for their preparation. The present invention also includes pharmaceutical compositions of such Afatinib salts and crystalline forms thereof or crystalline forms of Afatinib, methods of their preparation and the use thereof in the treatment of a patient in need thereof.

Salts and polymorphic forms of Afatinib

Manufacture of propylene and ethylene in a FCC unit. Each FCC riser comprises an acceleration zone, a lift stream feed nozzle, a main hydrocarbon stock feed nozzle, and an olefinic naphtha feed nozzle. Mixed FCC catalyst comprising at least 2 percent by weight pentasil zeolite and at least 10 percent by weight Y-zeolite is injected at the bottom of each FCC riser. Olefinic naptha is injected through the olefinic feed nozzle, main hydrocarbon stock is injected through the main hydrocarbon stock feed nozzle and lift stream is injected through the lift stream feed nozzle. Lift stream comprises olefinic Chydrocarbon stream and optionally steam and/or a fuel gas. Olefinic Chydrocarbon steam is cracked in the acceleration zone at 600 to 800&#xb0; C., 0.8 to 5 kg/cm(gauge) pressure, WHSV 0.2 to 100 hr up 1 and vapour residence time 0.2 to 5 seconds.

Fluid catalytic cracking (FCC) process for manufacturing propylene and ethylene in increased yield

A process is disclosed for enhanced recovery of propylene and LPG from the fuel gas produced in Fluid catalytic cracking unit by contacting a heavier hydrocarbon feed with FCC catalyst. In the conventional process, the product mixture from FCC main column overhead comprising naphtha, LPG and fuel gas, are first condensed and gravity separated to produce unstabilized naphtha, which is subsequently used in the absorber to absorb propylene and LPG from fuel gas. However, the recovery of propylene beyond 97 wt % is difficult in this process since unstabilized naphtha already contains propylene of 5 mol % or above. In the present invention, Cand lighter components from unstabilized naphtha are first stripped off in a separate column to obtain a liquid fraction almost free from propylene (&#x3c;0.1 mol %) and other LPG components. Such a stripped liquid fraction, after cooling to 20&#xb0; C. to 30&#xb0; C., is used in the absorber to absorb higher amounts of propylene and LPG from fuel gas, leading to improved recovery of propylene.
