Eleven examined working fluids can be sorted according to their thermal and exergy efficiencies from high to low performances as cyclohexane, n-hexane, R-113, n-pentane
and Iso-pentane, R-245fa, n-butane, Iso-butane, RC-318 and R-236fa, and at last R-227ea.
Densities of saturated liquid and vapor phases of the compounds involved in this work were obtained from the correlations of Lemmon and Span for toluene (34), Span and Wagner for n-pentane
(35), Wu et al.
After four weeks' storage, the n-pentane
content of both foam samples had dropped to below 0.
examines applications of N-pentane
and its consumers
and water, no clear correlation Of Ed with CNTs crystal structure is evident.
The solubility of pure polymers was studied in n-pentane
Toluene, n-heptane, n-pentane
, and acetone were obtained from Aldrich Chemical Company and were 99%+ pure.
Results showed that all-isopentane or an isopentane-rich blend with n-pentane
has the maximum potential for cost savings while maintaining or enhancing performance (see chart).
really an index of lipid peroxidation in humans and animals?
On the contrary, hydrocarbons, mainly cyclo- and n-pentane
, are used in several industrial productions, as they do not show cost or supply problems.
The primary contenders in North America are hydrofluorocarbons HFC-245fa and, to a lesser extent, HFC-134a (usually with high water levels for co-blowing with CO2), as well as the hydrocarbons cyclopentane, n-pentane
, and isopentane.
Yates live oil was recombined from stocktank crude oil by adding appropriate amounts of light ends, methane to n-pentane
, so as to match the Yates live oil composition.
