Patent number: 9074149Abstract: The current invention discloses a novel process and system to improve the quality of the slag product from a gasification process, thereby producing low-carbon marketable aggregate product. The inventive processes and systems employ a hindered-bed settler in conjunction with optional disengager and de-watering devices. A slag slurry stream from a gasification process is de-watered and the solids content is increased from less than 5% to greater than 30% via the de-waterer before being conveyed to a hindered-bed settler, wherein the carbon content is reduced from as much as 70% to less than 5%. Particles with a high carbon content are conveyed to a gravity settler, whereby they are concentrated and then recycled to the gasification reactor.Type: GrantFiled: January 5, 2010Date of Patent: July 7, 2015Assignee: Lummus Technology Inc.Inventors: Albert C. Tsang, Max W. Thompson, Rick Q. Honaker

Patent number: 8888876Abstract: The present invention relates to a system and process for gasifying feedstock such as carbonaceous materials. The invention includes partial combustion of dry solids and pyrolysis of carbonaceous material slurry in two separate reactor sections and produce mixture products comprising synthesis gas. The invention employs one or more catalytic or sorbent bed for removing tar from the synthesis gas. The inventive system and process allow a gasification to be carried out under higher slurry feeding rate and lower temperature with the provision to manage the tar being produced, therefore to increase the conversion efficiency of the overall gasification.Type: GrantFiled: May 8, 2013Date of Patent: November 18, 2014Assignee: Lummus Technology Inc.Inventors: Albert C.

Patent number: 8088188Abstract: A system and process for gasifying carbonaceous feedstock with staged slurry addition in order to prevent the formation of tar that causes deposition problems. Dry solid carbonaceous material is partially combusted, then pyrolyzed along with a first slurry stream comprising carbonaceous material in two separate reactor sections, thereby producing mixture products comprising synthesis gas. The second slurry stream comprising particulate carbonaceous material is fed to a drying unit downstream of a heat recovery zone along with the mixture product exiting the heat recovery zone The resulting final temperature of the second stage mixture products and dried particulate carbonaceous material is between 450° F. and 550° F., a temperature range that is typically not conducive to the emission of heavy molecular-weight tar species.Type: GrantFiled: April 1, 2011Date of Patent: January 3, 2012Assignee: ConocoPhillips CompanyInventors: David L. Breton, Albert C. Tsang, Max W. Thompson
