A system for removing sulfur from a gaseous stream includes (a) a reaction bed for receiving the gaseous stream and for reacting sulfur dioxide and at least some of the hydrogen sulfide of the gaseous stream into elemental sulfur to provide an elemental sulfur stream and a first product stream; and (b) a circulating fluidized bed comprising (i) a first region for receiving the first product stream and using a sulfur adsorption material to adsorb and remove any remaining hydrogen sulfide from the first product stream to generate saturated sulfur adsorption material and a second product stream substantially free of sulfur; and (ii) a second region for receiving a regeneration stream and for using the regeneration stream to regenerate the saturated sulfur adsorption material and to generate the sulfur dioxide.
摘要:
A device and method for producing a reformate fuel from a hydrocarbon gas source. The invention enables the conversion of a dilute hydrocarbon gas into a more easily consumable reformate fuel. Gases having low concentrations of hydrocarbons are concentrated using a concentrator into a gaseous or liquid concentrated VOC fuel. The concentrated VOC fuel is then converted into a reformate using a reformer. The reformate is more easily consumed by an energy conversion device such as a combustion engine, fuel cell, sterling engine or similar device that converts chemical energy into kinetic or electrical energy. The reformer enables complex hydrocarbon fuels that are not normally suitable for use in an energy conversion device to be converted into a reformate. The reformate may be directly supplied into the energy conversion device.
摘要:
A method of improve the removal of particulate matter, heavy metals, neutralizing acid, and kill microorganism pollutants, known to be in contaminated air volumes of occupied confined spaces, when exposed in close contact under pressure to a mixture of alkaline sorbent materials, having a known synergism between said pollutants using a self propelled fluidized bed reactor and packed bed filter apparatus system to optimize the contact collection efficiency of submicron particles and organic compounds.
摘要:
A low-pressure multifunctional filter separates CO2 and other air pollutants from flue, coal, natural and other gas mixtures. The separation agent is a solid carbon-rich sorbent, such as coke, charcoal, coal or activated carbon, that captures CO2 and other air pollutants at lower temperatures and liberates them at higher temperatures. The sorbent is regenerated by heating with direct steam, hot CO2 or other source of thermal energy. The recovered CO2-rich product can be used for enhanced oil recovery, enhanced methane recovery, and subsequent storage in depleted oil and gas reservoirs.
摘要:
A method and apparatus for removing sulfur from a hydrocarbon-containing fluid stream wherein desulfurization is enhanced by improving the contacting of the hydrocarbon-containing fluid stream and sulfur-sorbing solid particulates in a fluidized bed reactor.
摘要:
A boundary layer propulsion apparatus for propulsion of a fluid is provided. The boundary layer apparatus has a casing with an inlet and outlet. Supported in the casing is a tubular-shaped flow conduit which defines an interior space, the conduit positioned for rotation about its longitudinal axis. Extending from the conduit are multiple generally planar,generally parallel, spaced-apart disks which form multiple open annular spaces between the disks. Multiple ports provide fluid communication from the interior space of the flow conduit to the spaces between the disks. A motor or prime mover rotates the flow conduit which then imparts movement of the fluid from the interior space of the flow conduit, through the ports, along the adjacent spaces between the disks and then out of the casing through the outlet. A boundary layer turbine apparatus of similar design is also presented.
