Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases. The compound was isolated during studies on reactions between glycerol and gaseous hydrogen chloride. Upon heating, kerogen converts in part to liquid and gaseous hydrocarbons. The electrical dipole moment of gaseous sulfur trioxide is zero. Helium is commercially available in either liquid or gaseous form. Petroleum includes not only crude oil, but all liquid, gaseous and solid hydrocarbons. Shear waves decay rapidly in liquid and gaseous environments. They may cap even larger deposits of gaseous methane. This stream contained both gaseous and liquid components. Hybrid rocket engines use a combination of solid and liquid or gaseous propellants. Jupiter is composed primarily of gaseous and liquid matter. Even gaseous oxygen is dangerous in excess. Insolubility is the inability to dissolve in a solid, liquid or gaseous solvent. Exposure to very high concentrations of gaseous ammonia can result in lung damage and death. U-235 and U-238 isotopes by Gaseous diffusion.
