Patent HU-222969-B1 (HU)
Title: Process for generating electric energy, steam and carbon dioxide from hydrocarbon feedstock
Inventor: FJELLHAUG HENRIK O
IPC: C01B32/50
Filed: 1998-07-13
Abstract: A process producing electric energy, steam and carbon dioxide in concentrated form from a hydrocarbon feedstock. The process includes forming synthesis gas in an air driven autothermal reactor unit (ATR), heat exchanging the formed synthesis gas and thereby producing steam, treating at least part of the synthesis gas in a CO-shift reactor unit and carbon dioxide separation unit for formation of concentrated carbon dioxide and a lean hydrogen containing gas which is combusted in a combined cycle gas turbine for production of electric energy, and where air from the turbine is supplied to the ATR unit. The exhaust from the gas turbine is heat exchanged for the production of steam which together with steam generated upstream said unit is utilized in a power generator for production of substantially CO2-free electric energy. Steam may be fed to the gas turbine for diluting the hydrogen containing gas mixture. The process may also be combined with the production of synthesis gas products such as methanol and/or ammonia. Part of the gas from the carbon dioxide removal unit may be utilized in a fuel cell.

Filed: 2000-03-30
Abstract: L'invention concerne des disques optiques formatés pour enregistrer plusieurs flux audio aux contenus divers et permettant une lecture avec un flux vidéo unique, ceci pouvant générer une sortie audio au contenu inattendu par l'utilisateur selon la configuration du flux audio contenu dans le flux audio-vidéo (AV) lu. Cette situation peut prêter à confusion et amener l'utilisateur à changer la sortie audio après le début de la lecture. Afin d'éviter cela, des données indiquant le type de configuration du flux audio contenu dans chaque flux AV sur le disque optique sont mémorisées avec chaque flux audio. Ces données de type de flux audio sont présentées à l'utilisateur sur le même écran où un programme AV est sélectionné pour la lecture. L'utilisateur peut ainsi savoir avant que ne commence la lecture quel canal de flux audio est présélectionné pour la lecture, et peut ainsi changer le canal audio comme il le désire avant que ne commence la lecture.
