Abstract: Method of preparing and introducing fuel into the combustors of a gas turbine in which a hydrocarbon containing feed, oxygen and steam are introduced into a catalytic partial oxidation reactor at an oxygen to carbon ratio of between about 0.08 and about 0.25 and water to carbon ratio of between about 0.05 to about 0.5. The hydrocarbon containing feed contains no less than about 15 percent by volume on a dry basis of hydrocarbons with at least two carbon atoms and/or at least about 3 percent by volume of olefins. The fe oxygen and steam are introduced into the reactor at a temperature no greater than 600°C to produce a product stream at a temperat of between about 600°C and 860°C and that contains less than about 0.5 percent of olefins and less than 10 percent of hydrocarbon with two or more carbon atoms on a dry basis.

Abstract: método e aparelho para produzir uma corrente de gás natural substituto. um método e aparelho para produzir uam corrente de gás natural substituto a ser acrescentada a uma corrente de gás natural em que pelo menos uma parte de uma corrente de gás de refinaria é reagida em um reator catalítico para hidrogenar olefinas para formar hidrocarbonetos saturados. a extensão na qual hidrogênio e olefinas são reagidos no reator catalítico é controlada para reduzir a concentração de olefinas na corrente de gás natural substituto resultante com o gás natural. este controle pode ser efetuado por derivar parte do gás residual de refinaria para uma corrente de produto intermediária produzida pelo reator catalítico e formando assim a corrente de gás natural substituto a partir da corrente de gás de refinaria derivado e da corrente de produto intermediária.

Abstract: Carbon dioxide emissions within a refinery are reduced by reforming a hydrocarbon containing feed at low pres-sure to enhance the conversion of methane to hydrogen and carbon monoxide and thereby reduce methane slip. The hydrocarbon containing feed is composed entirely or at least in part of a refinery off gas. The resulting reformed stream is then subjected to wa-ter-gas shift conversion to form a shifted stream from which carbon dioxide is separated. As a result of the separation and the low pressure reforming, hydrogen containing fuel gas streams, that are thereby necessary lean in carbon dioxide and methane, are used in firing the steam methane reformer and other fuel uses within the refinery to reduce carbon dioxide emissions. The carbon diox-ide that is separated can be sequestered or used in other processes such as enhanced oil recovery.

Abstract: A catalytic reactor having a mixing section (10) connected to a downstream reaction section (12) containing a catalyst (44) to promote a reaction of oxygen and a hydrocarbon fed to the catalytic reactor. The mixing section (10) is provided with a flame arrestor (30) to prevent a stable flame from propagating should any reaction of oxygen and hydrocarbons occur during mixing. The flame arrestor (30) permits flow in both axial and radial directions to promote mixing. Baffle elements (32) and a downstream static mixer (34) can also be used. The catalyst (44) is preferably in the form of monolithic blocks (46) enclosed by a ceramic tube (48) that is maintained as a unitary catalyst assembly (44) that can be removed for replacement and installation of the catalyst (44) as a single unit.

Abstract: The amount of a ballast gas needed, to prevent combustion, deflagration, and/or detonations during a liquid phase reaction of molecular.oxygen and a flammable process liquid, is reduced by using a ballast gas other than nitrogen. The ballast gas is selected to have a boiling point lower than the boiling point of the flammable process liquid and selected to produce a higher limiting oxygen value (LOV) in a mixture with the flammable process liquid vapor and molecular oxygen than the LOV for the corresponding mixture substituting just nitrogen for the inerting gas.

Abstract: This invention is directed to a method for producing ethylene oxide comprising feeding ethylene, high purity oxygen and a ballast gas with a recycle gas in a catalyst filled reactor to form a gaseous mixture; passing the gaseous mixture from the reactor to a recovery unit to selectively separate ethylene oxide and carbon dioxide containing gas; passing at least a portion of the carbon dioxide containing gas to a stripping unit to selectively separate carbon dioxide and a waste gas; passing at least a portion of the waste gas to purge and another portion for recycling as the recycle gas; and recovering ethylene oxide from the recovery unit.

Abstract: Organic sulfur compounds contained in refinery off gas streams having either high ort low concentrations of olefins are converted to hydrogen sulfides which can be then be removed using conventional amine treating systems. The process uses a catalytic reactor with or without a hydrotreater depending on the olefin concentration of the off gas stream. The catalytic reactor operates in a hydrogenation mode or an oxidation mode to convert a majority of organic sulfur compounds into hydrogen sulfides.
