| 20080244975 | Reforming apparatus and method - A multiple adiabatic bed reforming apparatus and process are disclosed in which stage-wise combustion, in combination with multiple reforming chambers with catalyst, utilize co-flow and cross-flow under laminar flow conditions, to provide a reformer suitable for smaller production situations as well as large scale production. A passive stage by stage fuel distribution network suitable for low pressure fuel is incorporated and the resistances in successive fuel distribution lines control the amount of fuel delivered to each combustion stage. The fuel distribution system allows relatively constant fuel and air flow during turn up or turn down conditions. High efficiency is achieved by capturing heat from reforming syngas product to preheat gases before entering the reformer. Conditions that would produce unwanted coking or metal dusting are also eliminated or localized to locations within the apparatus outside the heat exchangers, but which locations can be cost effectively protected. Also, a chemical reactor is disclosed and which has a core composed of a stack of metal plates that are diffusion bonded in face-to-face relationship. A plurality of reaction zones are located within the core, as are a plurality of catalyst receiving zones, and both the reaction zones and the catalyst receiving zones are defined by respective aligned apertures in the plates. First and second channel arrangements are provided in the plates for transporting first and second reactants to reaction zones. Portions of the first channel arrangement that interconnect the reaction zones are formed as heat exchange channels. A third channel arrangement is provided in the plates for transporting a third reactant to catalyst receiving zones. Portions of the third channel arrangement are formed as heat exchange channels in proximity to the heat exchange channels of the first channel arrangement. | 10-09-2008 |

| 20120108681 | Multiple Reactor Chemical Production System - The present invention is a multiple reaction set for the production of chemicals by equilibrium limited reactions utilizing plate-type or extended surface heat exchangers. The heat exchangers cool the reaction products to condense methanol within the reaction products for separation, and to warm incoming feed reactants prior to entrance of the reactants into a reactor utilized for methanol production. The various reactors, heat exchangers, and separators can be formed as separated zones within enclosed vessels, thereby eliminating the need for separately constructed reactors, heat exchangers, and separators. Multi-stream plate-type of extended surface heat exchangers can be utilized to allow efficient cooling and methanol separation. The multiple reaction set can also be used for the recovery of methanol from a waste or purge gas stream utilizing multiple reactors, multiple plate-type or extended surface heat exchangers and multiple separators as a substitute for or in conjunction with a conventional methanol synthesis loop. | 05-03-2012 |

| 20080308094 | TROUGH REFLECTORS FOR SOLAR ENERGY COLLECTORS - A trough reflector for solar energy collection is constructed from transverse ribs which support a reflective surface. Side edge support rails mounted on ends of the ribs support linear edges of the reflective surface. The edge support rails have a channel-like construction with an inner flange member which is in contact with a top of the reflective surface, and a lip member extending from an outer flange member. The edge region of the reflective surface rests on the lip member with the edge of the reflective surface in contact with the outer flange member. A turning moment is applied to the edge regions of the reflective surface to ensure that the entire reflective surface is parabolic. An arcuate profile of ribs of the trough reflector is converted into a parabolic profile by the application of a force to the ends of the ribs. | 12-18-2008 |
