Abstract: 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.

Abstract: 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 (K2CO3) is impregnated thereon to form an adsorbent comprising potassium carbonate (K2CO3) 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.

Abstract: 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.
