Abstract:
The present invention provides a method and apparatus of processing material having an organic content. The method comprises heating a batch of the material ("E") in a batch processing apparatus (16) having a reduced oxygen atmosphere to gasify at least some of the organic content to produce syngas, The temperature of the syngas is then elevated and maintained at the elevated temperature in a thermal treatment: apparatus (18) for a residence time sufficient to thermally break down any long chain hydrocarbons or volatile organic compounds therein. The calorific value of the syngas produced is monitored by sensors (26) and, when the calorific value of the syngas is below a predefined threshold, the syngas having a low calorific value is diverted to a burner of a boiler (22) to produce steam to drive a steam turbine (36) to produce electricity ("H"). When the calorific value: of the syngas exceeds the predefined threshold syngas having a high calorific value is diverted to a gas engine (40) to produce electricity (F").

Abstract:
A process for the conversion of a hydrocarbon to CO 2 and electrical power is described comprising subjecting a gas mixture comprising a hydrocarbon feed stream and steam to an integrated reforming process including stages of steam reforming in a gas-heated reformer and secondary reforming to generate a reformed gas mixture, increasing the hydrogen content of the reformed gas mixture by subjecting it to one or more water-gas-shift stages, cooling the resulting hydrogen-enriched reformed gas and separating condensed water therefrom, passing the resulting de-watered hydrogen-enriched reformed gas to one or more stages of carbon dioxide separation to recover carbon dioxide, combusting the remaining hydrogen-containing fuel stream with an oxygen containing gas in a gas turbine to generate electrical power and passing the exhaust gas mixture from the gas turbine to a heat recovery steam generation system that feeds one or more steam turbines to generate additional electrical power.

A method of recycling a tail gas includes converting sulfur present in an acid gas stream into elemental sulfur Io produce a tail gas and recycling the tail gas to at least one of a gasification reactor and a gas removal subsystem.
Abstract:
The invention relates to a synthesis gas-based fuel system (8) comprising a main synthesis gas pipe (9) that branches off a gasification device (10). A synthesis gas storage tank (33) is connected to the main synthesis gas pipe (9) via a first secondary pipe (34). The invention further relates to a method for operating such a synthesis gas-based fuel system (8).
Abstract:
Изобретение относится к области переработки угля и производства продуктов, получаемых в результате этой переработки. Сущность изобретения заключается в том, что энерготехнологический комплекс, состоящий из газификатора, котла, фреонового энергоблока, водородного сепаратора и газопоршневого энергоблока, дополнительно снабжен программатором с исполнительными механизмами и телекоммуникациями. Управление через компьютер процессом переработки угля предусматривается с возможностью получения от одного до нескольких продуктов газификации, например, кокса, электроэнергии, тепла, водорода одновременно в различных пропорциях путем изменения режима сжигания угля и режимов работы энергоблоков. Котел, водородный сепаратор и газопоршневой энергоблок установлены вблизи газификатора, а фреоновый энергоблок размещен между котлом и потребителями горячей воды, с возможностью его работы на обратном потоке этой воды.
