Hybrid CO2 Energy Park

How a dual carbon captured CO2 oil energy loop would work to produce both
carbon-neutral big electricity and carbon-neutral combustion fuels: Gasoline, Diesel, Jet Fuel, Heating Gas

All the different process heats at this facility would be carbon captured into a "CO2 Sewer" system
or, if you don't want to bother with oil, advanced nuclear would produce the same results with a simpler system.

      The Dual Carbon Captured CO2 Loop Energy System   

Dual carbon capture loops to make both Clean Grid Electricity - - - and Carbon-neutral Gasoline, Diesel, Jet Fuel, Heating Gas
If you are an oil man worried about your depleted oil patch turning into a "Stranded Asset", the above suggestion makes a hell of a lot of sense.

 What are the images above portraying?  The world has over 50,000  coal power plant sites.  They have the "Right Stuff" for upgrading into "energy industrial parks" to produce large volumes of non-climate changing electricity for the grid and clean carbon-neutral personal fuels such as gasoline, diesel, jet fuel, and heating gas from depleted oil patches that will safely consume the large amounts of CO2 necessary to flush out their unreachable remaining oil.

7   DEDICATED CO2-EOR Oil Field: An electric utility buys up a depleted oil field and dedicates the CO2-recovered oil to the exclusive production of captured CO2 electricity.
8   CO2 injection well to flush out immobile oil from depleted oil field.  This is "CO2 Capture and Use (CCU)".
9   Oil production well to recover oil that has been freed up by "Enhanced Oil Recovery" process.
10   Small oil refinery to remove impurities from recovered oil, separate jet fuel for powering energy park from heavier plastics and bitumen feedstocks.  

 All the heat energy at the above industrial site would come from the extremely hot and clean heat produced by oxyfuel carbon captured combustion.  The power plant could be fueled by either gas or oil.  Oil is shown.  If gas were used to oxypower the turbines instead, the captured CO2 could still be used for Enhanced Oil Recovery (EOR).  

 Since the jet engine will be "breathing" a mixture of oxygen diluted with CO2, its turbine blades and buckets will have to be resized to compensate for the fact sound travels only 80% as fast in CO2 as in air.

 Some EOR enthusiast's claim that EOR oil can be considered 70% CO2-free after subtracting the flushing CO2 that remains in the ground.

 Oxygen-boosted fossil fuel heat in excess of 1,700 degrees Fahrenheit is needed to split hydrogen from water, extract air captured carbon dioxide from solid calcium carbonate, and for some of the catalytic reactions involved in making carbon-neutral combustion fuels from air's CO2 gas and hydrogen gas.  So, to power the entire industrial park, the oxygen producing air reduction plant should be perhaps 50% larger than what is needed to supply only the combined cycle electricity plant.  Today's nuclear reactors are 1,000F too cool and wind and solar are 1,000 times too weak to power this industrial park.

 Example:  has a 4 inch, 20 megaWatt (thermal), 1,500 psi, 3,200F, oil or gas oxyfuel gas generator that should meet the needs of a decarbonized future.  A similar 12 inch, 200 megaWatt (Thermal) unit is also available for a ten times larger plant.  They also have oxyfuel interstage steam reheaters available.

 The extremely high temperatures available with oxygen-combustion make many different high-efficiency topping and bottoming cycles (pdf) practical - for example: Instead of typical 30% efficient electricity generation, 60% efficient combined cycle electricity generation is now state-of-the-market.  Similarly, high efficiency combined cycle air carbon capture (CDR) and electricity generation, and combined cycle water splitting combined with methanol fuels catalysis are possible.  Oxygen-enriched combustion is often a good way to both improve fuel efficiency and reduce unwanted emissions.  Notice the purple "CO2 Sewer" connected to all those different oxygen-combustion fires in the sketch above?.

(Oxyfuel-hot heat for capturing air's CO2 and making carbon-neutral gasoline from the captured CO2 could also come from TRISO-fueled extremely hot high temperature helium gas cooled (HTGR) nuclear reactors.  The Chinese are building 40 of them now - the HTR-PM  [pdf]  for a power complex at Rongcheng, Shandong Province, China.)
