Patent number: 10487280Abstract: A process and apparatus are provided for reducing content of tar in a tar containing syngas. The process includes contacting the tar containing syngas with a molecular oxygen containing gas in a first reaction zone to produce a gas mixture. The gas mixture is passed through a heat treatment zone maintained at a temperature between about 900° C. to about 2000° C. for a contact time of about 0.5 to about 5 seconds. In this aspect, at least a portion of the tar undergoes at least partial oxidation and/or cracking to produce a hot syngas.Type: GrantFiled: October 20, 2014Date of Patent: November 26, 2019Inventors: Peter Simpson Bell, Ching-Whan Ko, Joseph Golab, Bernard Descales, Julien Eyraud

Patent number: 9604888Abstract: Method of producing ethylene and, optionally, propylene by subjecting a feedstock to steam cracking to produce a first olefin containing stream; heating an ethanol containing stream with heat from a steam cracker; passing the heated ethanol containing stream over a dehydration catalyst at a temperature between 200 C to 500 C preferably 250 C to 450 C to produce a second olefin containing stream; and combining the first and second olefin containing streams to give an initial product stream containing ethylene and optionally propylene. The initial product stream is subjected to purification including at least i) water content reduction ii) hydrogen content reduction iii) reduction of content of molecules containing 4 or more carbon atoms and iv) ethane content reduction.Type: GrantFiled: June 26, 2012Date of Patent: March 28, 2017Assignee: INEOS EUROPE AGInventors: Laurent Caranoni, Bernard Descales, Neil Turnbull, Vaughn Clifford Williams

Patent number: 9028571Abstract: A process and system for cooling syngas provides effective syngas cooling and results in reduced levels of fouling in syngas cooling equipment. A process for cooling syngas includes blending syngas with cooled recycled syngas in an amount effective for providing a blended syngas with a temperature at an inlet of a syngas cooler of about 600° F. to about 1400° F. The blended syngas changes direction of flow at least once prior to the inlet of the syngas cooler.Type: GrantFiled: December 13, 2011Date of Patent: May 12, 2015Assignee: Ineos Bio SAInventors: Peter S. Bell, Nicolas Vanhecke, Bernard Descales
