Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Quantum Carnot Bound from Petz Recovery Maps
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.
