A steam reheat process is provided to enhance a thermal power cycle, and particularly a renewable steam thermal cycle. An oxyfuel combustion gas generator is provided which combusts a hydrogen and/or carbon containing fuel with an oxidizer of primarily oxygen to generate products of combustion including steam and/or carbon dioxide. Water from the thermal cycle is directed to the reheater for mixing with the products of combustion within the reheater to generate a working fluid containing steam. This steam is routed through a turbine or other expander and power is outputted from the system. The water is optionally thereafter condensed and at least partially routed back to the thermal cycle. Any carbon dioxide within the working fluid can be separated in a condenser downstream of the expander for capture of the carbon dioxide, such that increased power output for the thermal power cycle is achieved without atmospheric emissions.

An arrangement including at least one steam turbine and one condenser is provided. Further, a method to operate such an arrangement is provided. A regenerative deheater is arranged in the steam flow between the steam turbine and the condenser, by which the steam, superheated exhaust steam, exiting the steam turbine is cooled down before entering the condenser and by which a feed-water stream is heated up.

The power plant combusts a hydrocarbon fuel with oxygen to produce high temperature high pressure products of combustion. These products of combustion are routed through an expander to generate power. The products of combustion are substantially free of oxides of nitrogen because the oxidizer is oxygen rather than air. To achieve fast starting, oxygen, fuel and water diluent are preferably stored in quantities sufficient to allow the power plant to operate from these stored consumables. The fuel can be a gaseous or liquid fuel. The oxygen is preferably stored as liquid and routed through a vaporizer before combustion in a gas generator along with the hydrocarbon fuel. In one embodiment, the vaporizer gasifies the oxygen by absorption of heat from air before the air is routed into a separate heat engine, such as a gas turbine. The gas turbine thus operates on cooled air and has its power output increased.

Methods and apparatus relate to recovery of in situ upgraded hydrocarbons by injecting steam and hydrogen into a reservoir containing the hydrocarbons. A mixture output generated as water is vaporized by direct contact with flow from fuel-rich combustion provides the steam and hydrogen. The steam heats the hydrocarbons facilitating flow of the hydrocarbons and reaction of the hydrogen with the hydrocarbons to enable hydroprocessing prior to recovery of the hydrocarbons to surface.

A method is provided for hydrogen production from a hydrogen and carbon containing fuel combusted within an oxyfuel combustor. The oxyfuel combustor combusts hydrogen and carbon containing fuel with oxygen at a non-stoichiometric ratio, typically fuel rich. In such an operating mode, products of combustion include steam, carbon dioxide, carbon monoxide and hydrogen. These products of combustion are then passed through a hydrogen separator. Remaining products of combustion can be optionally combusted at a stoichiometric ratio with oxygen in a second oxyfuel combustor discharging substantially only steam and carbon dioxide. A turbine or other expander can be provided downstream from the gas generator to produce power and eliminate carbon monoxide from the system. The system can be operated in a second mode where the gas generator combusts the fuel with oxygen at a stoichiometric ratio to maximize electric power generation without hydrogen production at periods of peak power demand.

Methods and systems generate steam for injection in a well to facilitate oil recovery. Water is preheated at a central processing facility, transported to a well pad by hot water lines, and converted to steam by a steam generator at the well pad.
