The overhead product of the crude unit contains hydrogen, methane, carbon dioxide, hydrogen sulfide, and hydrocarbons up to butanes and some pentanes. It is usually sent to a set of distillation columns known as a saturate gas plant for recovery of propane and butane for sale. The lighter gases are then used as refinery fuel.

Petroleum Gases and Naphtha. Methane is the main hydrocarbon component of petroleum gases. Lesser amounts of ethane, propane, butane, isobutane, and some 0 + light hydrocarbons also exist. Other gases such as hydrogen, carbon dioxide, hydrogen sulfide, and carbonyl sulfide are also present. 

For the same coal, low-temperature liquids contain more tar acids and tar bases than high-temperature liquids. With high-temperature carbonization, the liquid products are water, tar, and crude light oil. The gaseous products are hydrogen, methane, ethylene, carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia, and nitrogen. The products other than coke are collectively known as coal chemicals, or by-products.

The hydrate forming gases include light alkanes (methane to n-butane), carbon dioxide, hydrogen sulfide, nitrogen, and oxygen. 

The hydrate-forming gases include light alkanes (methane to isobutane), carbon dioxide, hydrogen sulfide, nitrogen, and oxygen. As hydrate-forming species in laboratory experiments it may be convenient to use substances such as tetrahydrofuran or short-chained CFCs, since gas hydrates are readily formed at temperatures between 3 and 8 C, at 1 atmos.

Physical properties of NMP are given in Table 14-5 and in Figure 14-12. Equilibrium solubility data for carbon dioxide, hydrogen sulfide, methane, and propane are presented in Table 14-15. The data of Boston and Schneider (1971) were obtained with a gas mixture containing 97.10% methane, 1.02% propane, 1.17% carbon dioxide, and 0.71% hydrogen sulfide at a total pressure of 850 psia and a temperature of 74°F. Additional gas solubility data are given in Table 14-4.
