20090283445 | FCC reactor and riser design for short contact-time catalytic cracking of hydrocarbons - The present invention is an improved design and operation of a short contact time Fluid Catalytic Cracking (FCC) Reactor wherein the upper internal riser and a lower internal riser are in fluid connection with one another and provide an improved disengaging zone for entraining the vapors from the dilute phase area of the FCC reactor. Detailed preferred embodiments include improvements over the prior art to the internal central riser, riser termination apparatus, cyclone separators, and a coke mitigation baffle system, as well as associated improved fluid catalytic cracking processes utilizing the novel reactor design. | 11-19-2009 |
20110240526 | Debris Separation Device and Method of Use - A device for use in separating debris from a flowing stream which comprises a substantially hollow, substantially conical shaped structure comprising a top end member and a plurality of adjacently positioned side members angularly extending from a top end member to a substantially circular bottom end. The top end member has a smaller diameter than the circular bottom end. The adjacently positioned side members are configured to provide multiple tiers in a vertical plane in the conically shaped structure. The multiple tiers comprise a plurality of apertures in a horizontal plane in the conically shaped structure. The plurality of apertures are configured for separating large debris particles, generally formed from coke and spent catalyst, from a flowing fluidized catalytic cracking stream, and directing the captured debris toward the circular bottom end of the device. A method of separating debris from a flowing stream is also provided. In particular, the device and method are useful for separating coke deposits in a fluidized catalytic cracking (FCC) process. | 10-06-2011 |
20130061755 | Integrated Adsorber Head and Valve Design and Swing Adsorption Methods Related Thereto - An adsorber with minimal dead volume especially suited to reverse-flow applications comprises: a) an adsorber body; b) a first head engaged with said adsorber body; c) a first conduit extending from outside said head to at least partially through said head; and d) a first valve in flow communication with said first conduit controlling fluid flow along a flow path extending from the first valve and through the adsorber body. The adsorber is especially suited for use in a process for swing adsorption separation processes. | 03-14-2013 |

20130327216 | Methods of Removing Contaminants from a Hydrocarbon Stream by Swing Adsorption and Related Apparatus and Systems - A swing adsorption process for removing contaminants from a gaseous feed stream through a combination of a selective adsorbent material containing an effective amount of a non-adsorbent filler, adsorbent contactor design, and adsorption cycle design. | 12-12-2013 |
20130340619 | Apparatus and Systems Having a Reciprocating Valve Head Assembly and Swing Adsorption Processes Related Thereto - Provided are apparatus and systems having a poppet valve assembly and swing adsorption separation techniques related thereto. A poppet valve includes a valve body, a plurality of static valves fixedly secured to the valve body and a single dynamic poppet valve having a plurality of openings. The plurality of static valves align and mate with the plurality of openings. The single dynamic poppet valve reciprocates to selectively open and close the plurality of static valves. | 12-26-2013 |
20140013955 | Apparatus and Systems Having an Encased Adsorbent Contactor and Swing Adsorption Processes Related Thereto - Provided are encased parallel channel adsorbent contactor apparatus and systems and swing adsorption processes related thereto. Encased parallel channel adsorbent contactors are useful in swing adsorption processes. A plurality of the encased adsorbent contactors are loaded and sealed together in a swing adsorption vessel such that substantially an entire feed stream must pass through the channels of the contactors and not through stray gaseous stream paths between contactors. | 01-16-2014 |
20140216254 | Apparatus and Systems Having a Rotary Valve Assembly and Swing Adsorption Processes Related Thereto - Provided are apparatus and systems having a rotary valve assembly integrated with a reciprocating valve assembly to perform swing adsorption processes.
