Pressure swing adsorption: energy economics?

enthalpy of adsorption (exothermic), partial pressures and temperatures. This effect is called differential loading. By pulsing gas into a chamber at high pressure, commonly 10-30 bar, gases with lower affinity…

Acetylene: production costs?

…market volumes. This is because of acetylene’s combustion properties, forming a very high flame temperature around 3,000◦C, high enthalpy of combustion of 50 MJ/kg, a fast flame speed of 10-12…

Density of gases: by pressure and temperature?

Density of gases

enthalpy of combustion in kJ/kg, and then juggling the energy units. A nice round number: the primary energy density of methane is 10 kWh/m3 at 1-bar and 20ºC, increasing with…
