20120172649 | PROCESS FOR RECOVERY OF PROPYLENE AND LPG FROM FCC FUEL GAS USING STRIPPED MAIN COLUMN OVERHEAD DISTILLATE AS ABSORBER OIL - 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, C | 07-05-2012 |

20140357912 | PROCESS FOR CATALYTIC CONVERSION OF LOW VALUE HYDROCARBON STREAMS TO LIGHT OLEFINS - 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. | 12-04-2014 |

20130306906 | ADIABATIC REGENERATION OF SULFUR CAPTURING ADSORBENTS - The present invention provides a process for regeneration of the sulfur capturing spent adsorbents after sulfur capturing using a hydrolyzing agent under adiabatic conditions. In accordance with the process of the present invention hydrolyzing agent is introduced to the spent adsorbent in a controlled manner such that the exothermic heat generated within the adsorbent bed does not rise above the predetermined temperature limit. | 11-21-2013 |
