Publication number: 20120294783Abstract: Reformer and method for producing hydrogen and steam where steam is used for steam-assisted extraction of heavy hydrocarbons. Steam is injected into a hydrocarbon-containing reservoir. Hydrocarbons are extracted from the reservoir along with produced water. Hydrogen is produced in a catalytic steam hydrocarbon reformer. Combustion product gas from the reformer is used to generate wet steam in a once-through steam generator from produced water recycled from the reservoir. The wet steam is used for the steam-assisted extraction of heavy hydrocarbons. The reformer has a heat exchanger section where a heat exchanger is suitable for processing the produced water by once-through steam generation and is suitable for mechanical cleaning.Type: ApplicationFiled: July 12, 2012Publication date: November 22, 2012Applicant: Air Products and Chemicals, Inc.Inventors: John Eugene Palamara, David Anthony Zagnoli, William Frederick Baade

Patent number: 8303683Abstract: Guard layers are employed in the adsorbent beds of rapid cycle pressure swing adsorption (RCPSA) devices to protect the adsorbent therein from certain contaminants (e.g. water vapour). Conventional PSA devices typically pack the guard layer with as much guard material as is practical. In RCPSA devices however, the performance of the guard layer can be improved by using a reduced amount of guard material and increasing access to it. Such embodiments are characterized by guard layers with a channel fraction of greater than 50%.Type: GrantFiled: January 23, 2008Date of Patent: November 6, 2012Assignee: Air Products and Chemicals, Inc.Inventors: Andre Jason Boulet, Amy Chiu, Brian G.
