In all SE cases, the equilibrium conversion is close to unity over a wide range of pressures and temperatures. At 𝜆 = 2, the only exceptions are at low pressure, but in many cases the equilibrium conversion is not reached at low temperatures or high GHSVs. With increasing sorbent ratio, the equilibrium is further shifted towards full conversion and it is also approached under a wider range of conditions. Finally, at the near infinite sorbent ratio of 𝜆 = 1000, the near full equilibrium conversion is reached under all conditions, with the exception of 350 °C, 20 bar and high GHSV. The possibility of reaching near full single-pass conversion poses a major advantage of SEAS, as it might enable a process that does not require recycling of reactants and evades purging losses. On top of that, the recycle periphery, e.g., compressors and heat exchanges, can be omitted.
