The main hydrocarbon properties which will influence process design are ...

Write a play. The play should feature a family of hydrocarbon molecules. The father can be Octane, the mother Pentane, and the children Propane and Methane. There can be a complex cousin, 3-Methyl Heptane, and a twisted uncle, Benzene. The characters have personalities dictated by their hydrocarbon properties. Make the setting appropriate for hydrocarbon characters in a sculpture garden. Have the characters bond. Use your imagination. Produce the play for your class. 

During the last two and half decades or so the picture has dramatically changed, and, toluene is no longer considered a stepchild in the family of aromatic hydrocarbons. Properties of toluene, both commercial grade, and nitration grade are as follows [1,2] ...

The physical properties of alcohols lay somewhere between the physical properties of hydrocarbons and water depending upon the R — and —OH groups that make up the alcohol molecule. The hydrocarbon properties become more significant as the number of carbon atoms in the molecule increases. Similarities to water become more obvious in smaller molecules. 

Only hydrocarbon properties are discussed in this section because most of the nonhydrocarbons are prone to oxidation or degradation and are deleterious to lubricant performance. However, organosulphur molecules are known to act as naturally occurring antioxidants and it is frequently desirable to retain some of these in a refined base oil. 

Holba et al. 1996 Edman Burk 1999). Within the same field, lightly to severely biodegraded oils often co-exist with pristine unaltered oils, resulting in large within-field hydrocarbon property variations. Available data, discussed below, do not suggest that biodegradation has influenced Magnolia hydrocarbon fluids. 

Formation waters are often very saline, often containing more than 200 000 ppm total dissolved solids (Ryder et al. 1996). In addition, the in-situ connate water is most often present as an irreducible (non-mobile) water phase (Law 1984a,b, 1985 Ryder et al. 1996). The hydrocarbon properties vary depending on the type of BCGS, the source rock characteristics, and the effects of burial history on temperature and pressure gradients. 

Chlorinated Hydrocarbons. Properties of some chlorinated hydrocarbon insecticides are given in Table VI. All of the compounds, except for lindane, are insoluble in water. DDT is about ten times more insoluble than the other chlorinated hydrocarbons. The vapor pressure of the compounds are classified as follows low(0.1 -0.9 X 10 mm Hg)—DDT, endrin, and dieldrin, moderate (1.0-9.9 X 10 mm Hg)— toxaphene and aldrin, high (10-99 X 10 mm Hg)—chlordan and lindane, and very high (100-999 X 10" mm Hg)— heptachlor.

Substances considered in a compilation of the thermodynamic properties of refrigerants include hydrogen, parahydrogen, helium, neon, nitrogen, air, oxygen, argon, carbon dioxide, hydrocarbons (e.g. methane, ethane, propane, butane, isobutane, ethylene, and propene), and fluoro-and fluoro-chloro-hydrocarbons. Properties listed include those for the liquid and saturated vapour, superheated vapour, and unsaturated vapour. In addition, pressure-enthalpy, and in some instances pressure-entropy, diagrams are provided.
