Decarbonized gas: ship LNG out, take CO2 back?
Can you transport CO2 in LNG carriers? This 14-page report explores an option to decarbonize global LNG: (i) capture the CO2 from combusting natural gas (ii) liquefy it, including heat…
Thermodynamic cycles: Carnot, Brayton and Rankine Data?
…Over time we will add more data to this file on the thermodynamics of different working fluids, including their Enthalpy, Entropy, Specific Heats, Cp/Cv, latent heat (where relevant) and densities….
Tree seedlings: costs and economics?
…warmer climates, have a typical cost of 7c/seedling. Conversely, in colder climates, seedlings maybe grown in containers, in heated greenhouses, which also has the advantage of permitting earlier growing and…
Verbio: bio-energy technology review?
…bio-ethanol plants and bio-methane plants, then recirculating the stillage. Some nice flow diagrams are copied in our data-file. But most interestingly, halving the heat use on a bio-ethanol facility, and…
CCS: amine degradation rates?
…as catalysts, especially metals. Sulphur impurities produce heat stable salts. Evaporative losses correlate with temperature. Operating power plants at partial loads or as peakers can also increase evaporative emissions. Some…
Market sizing: what if CO2 abatement costs are distributed like US income?
…extend beyond simply cost. And there will always be a few downright lunatics who actually consider building small-scale wind turbines or drilling the bore-holes for a ground-source heat pump at…
Magnets and permanent magnets: company screen?
…include electric motors, including for electric vehicles; electric compressors, especially for HVAC applications and heat pumps; wind turbines. More mundanely, permanent magnets are also sold into ordinary household appliances like…
Electric vehicles: motors and magnets?
…power supply in. Another alternative is to use induction, to magnetize the rotor core, but core losses and iron losses also leak power (impacting efficiency by 2-7pp) and generate heat…
Purified terephthalic acid: PTA production costs?
…process heat for the cracking/reforming of naphtha. Energy costs are a major contributor to PX production costs, but less significant for oxidizing PX into PTA. How does the cost of…
Gas dehydration: costs and economics?
…in an absorber unit. Then the water can be stripped from the TEG solution by heating to 200ºC in a reboiler unit. Many readers will note this is effectively the…
