Abstract: A method for reducing the loss of solvent during carbon dioxide capture from flue gas in an amine based solvent process by the steps of feeding a flue gas containing carbon dioxide to an absorber column containing an amine solvent; absorbing carbon dioxide in the amine solvent forming a rich solvent; feeding the rich solvent to at least one inter-stage cooler; recovering the rich solvent and feeding the rich solvent to a regeneration column; separating the carbon dioxide from the rich solvent and recovering the carbon dioxide to form a lean solvent; feeding the lean solvent to the absorber column. The improvement is realized by one of feeding steam to the flue gas; feeding steam to the absorber column after introduction of amine solvent; feeding the flue gas stream to a demister before feeding to the absorber column or increasing the lean solvent inlet temperature into the absorber column.

Abstract: A method for producing hydrogen in a steam methane reformer is disclosed. The method provides for the steps of feeding a mixture of fuel and air to a steam methane reformer; feeding a mixture of steam and hydrocarbons to the steam methane reformer; contacting the steam and hydrocarbons with a metal monolith supported catalyst; providing an electric current to the metal monolith supported catalyst; and recovering the hydrogen. The electric current applied to the metal monolith supported catalyst will encounter electrical resistance which will create heat. This heat can supplement that provided for by the reaction of the fuel and air allowing for a reduction in fueling costs as well as treatment costs of the resultant flue gas.

Abstract: A method for separating carbon dioxide from a flue gas stream wherein the flue gas stream is fed to an absorber column thereby producing a carbon dioxide depleted flue gas stream and wherein carbon dioxide absorbed from the carbon dioxide rich flue gas stream in the solvent is fed from the absorber column to a stripper column as a carbon dioxide rich solvent blend. The method is an improvement over prior carbon dioxide separation process by feeding the flue gas stream to a gas pre-treatment device prior to feeding into the absorber column preferably for decreasing the oxygen content in the flue gas and recycling a carbon dioxide product from the stripper column to the absorber column to increase the carbon dioxide content in the flue gas.

Abstract: A process for producing hydrocarbons is disclosed in which a first feed substream and a second feed substream are obtained from a hydrocarbonaceous feed stream, of which the first feed substream is converted by means of partial oxidation or autothermal reforming to a first synthesis gas stream and the second feed substream is converted by means of steam reforming to a second synthesis gas stream and subsequently combined with the first synthesis gas stream to give a third synthesis gas stream, of which at least a first portion is converted by Fischer-Tropsch synthesis to a crude product stream comprising hydrocarbons of different chain lengths, from which light hydrocarbons are separated in a tail gas, in order to recycle them and use them in the partial oxidation or autothermal reforming. The characteristic feature here is that unsaturated hydrocarbons are separated from at least a portion of the tail gas.

Abstract: A method for producing urea. A methane-containing feed gas stream is reacted with oxygen by partial oxidation to form a synthesis gas stream containing hydrogen and carbon monoxide. The carbon monoxide is reacted with water in a water gas-shift reaction to form carbon dioxide and hydrogen. The synthesis gas stream is separated into a first synthesis gas substream a second synthesis gas substream. The first synthesis gas substream is subjected to pressure-swing adsorption to separate hydrogen and the second synthesis gas substream is subjected to temperature-swing adsorption to separate carbon dioxide. The separated is reacted with nitrogen to form ammonia and the ammonia is reacted with the carbon dioxide to form urea.

At least CO2 is removed from the feed gas in a scrubbing of the feed gas by means of a scrubbing medium, before the feed gas is fed to the syngas generation step.

Abstract: A system for enhanced oil recovery from an oil field that uses the associated gases collected to produce synthetic crude oil from a GTL plant. The pressure in the oil field is maintained by injecting nitrogen obtained from an ASU. The ASU is powered by an associated power plant that uses oxygen produced by the ASU and the Fisher Tropsch tail gases (hydrogen and steam) of the GTL plant. Nitrogen recovered from the tail gas of the power plant boosts the available nitrogen needed for the enhanced oil recovery operation.
