Propane Removal from Propane-Air Mixtures by Soil Beds

Deflagration Parameters of Propane–air Mixtures in a Closed Cylindrical Vessel

În prezenta lucrare a fost realizat un studiu asupra evoluţiei presiunii în timpul exploziei sub formă de deflagraţie produse în amestecuri propan-aer aflate într-o celulă cilindrică (Φ = 10 cm; h = 15 cm) cu aprindere centrală, la diferite concentraţii iniţiale de propan (între 2.60 şi 5.70%, in vol.), la diferite presiuni iniţiale (între 0.3 şi 1.3 bar) şi la temperatura iniţială ambiantă. Su...

The Effects of Platinum on Propane/Air Stagnation Flow Flames

Assessment of Propane in North American Residential Air Conditioning

Three unitary split systems were evaluated for use with propane as the refrigerant. These three systems were then compared to systems using hydrochlorofluorocarbon (HCFC) R-22 and hydrofluorocarbon (HFC) R-410A for environmental effectiveness. The propane systems included one using safety measures, another using propane with flame suppressant, and one using a secondary heat transfer loop to iso...

Radiant heat from propane jet fires

Sonic propane jet fire experiments were carried out in absence of wind, with visible flame length ranging between 2.2 and 8.1 m. The thermal radiation intensity increased with the mass flow rate and the flame length. The net heat released was also computed and a correlation for the flame length as a function of Q is proposed. The surface emissive power and the fraction of heat irradiated were e...

Propane-d6 Heterogeneously Hyperpolarized by Parahydrogen

Long-lived spin states of hyperpolarized propane-d6 gas were demonstrated following pairwise addition of parahydrogen gas to propene-d6 using heterogeneous parahydrogen-induced polarization (HET-PHIP). Hyperpolarized molecules were synthesized using Rh/TiO2 solid catalyst with 1.6 nm Rh nanoparticles. Hyperpolarized (PH ∼ 1%) propane-d6 was detected at high magnetic field (9.4 T) spectroscopica...
