A process for reducing pressure of a vapor stream wherein the vapor stream rotates a turbine wheel within the turbine to transmit rotational movement to an electrical generator and generate electricity. The resulting lower pressure vapor stream reduces a partial pressure of a hydrocarbon vapor or is injected into a reactor to reduce a temperature in the reactor. A recovered electric power measuring system comprises at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data from a sensor on an electrical powerline connected to a generator of a turbine, the turbine in fluid communication with a vapor stream wherein the turbine reduces the pressure of the vapor stream and the resulting lower pressure vapor stream is injected into a reactor to reduce a temperature in the reactor or to reduce a partial pressure of hydrocarbon vapor in the reactor.

The invention relates to a power plant (1) for generating electric energy (100) and process steam (200), comprising: —a gas turbine (2) for driving a first generator (3) in order to generate electric energy (100) by combusting a fuel into flue gas (300), —a steam turbine (4) for driving a second generator (5) in order to generate electric energy (100), comprising a first stage (4a) for converting fresh steam (400) into residual steam (201), which constitutes at least part of the process steam (200), and —a waste heat steam generator (6) for generating the fresh steam (400) from fresh water (500) using the exhaust heat of the flue gas (300), wherein —the residual steam (201) has a residual steam pressure which is lower than the pressure of the fresh steam (400), —the waste heat steam generator (6) comprises a pre-heater (7) for pre-heating the fresh water (500) in order to form feed water (600) and an evaporator (8) for evaporating the feed water (600) in order to form the fresh steam (400), and —the feed water (600) has a feed water pressure which is higher than the residual steam pressure. The invention is characterized by a throttle valve (9, 14) for expanding part of the feed water (600) either at the residual steam pressure in order to generate an additional steam (202) or at a drive steam pressure which is lower than the residual steam pressure in order to generate a drive steam (700) for operating a second stage (4b) of the steam turbine (4).

A pump uses the steam hammer effect to pump water from a reservoir into a control volume. Steam is injected into a water conduit extending between a liquid water reservoir and the control volume forms a liquid steam interface. Steam within the conduit condenses on the interface creating a region of partial vacuum. Water accelerates into the region of partial vacuum and is vented into the control volume, flow being controlled by a valve.

Effluent water is combined with carbon dioxide sourced from a carbon dioxide-containing emission stream to produce a reaction solution. The pH of the reaction solution is controlled to induce precipitation of a carbonate salt from the reaction solution.
