TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The hydrocarbon contains 1-5 carbon atoms, and is preferably methane, ethane, propane, n-butane, isobutane and/or natural gas. The amine salt comprises an ammonium and/or organoammonium cation. The cation is derived from amines of formula (a) or (b). The onium compound is of formula (I). The anion is derived from formic acid, acetic acid, propionic acid, butyric acid, glycolic acid and/or nitric acid.RaRbRcN (a)R1R2R3X+ Y- (I)Ra to Rd = H, 1-3C alkyl, or OH-substituted 1-3C alkyl;Re = (CH2)m or (CH2)nZ(CH2)p;Z = O, S or CHRf;m = 3-7;n = 1-3;p = 1-4;Rf = H, 1-3C alkyl or OH-substituted 1-3C alkyl;R1, R2 = 4 or more C alkyl optionally with substituent(s), or heteroatom(s);R3 = 4 or more C organic moiety optionally with substituent(s), or heteroatom(s);X = S, NR4 or PR4;R4 = H, alkyl, aryl, alkylaryl, alkenylaryl or alkenyl, preferably containing 1-20 C atoms optionally with substituent(s), or heteroatom(s);Y- = hydroxide, halide, carboxylate, sulfate and/or organic sulfonate.Preferred Compound: The amine is ammonia, methylamine, ethylamine, n-propylamine, iso-propylamine, dimethylamine, diethylamine, di-n-propylamine, trimethylamine, triethylamine, tri-n-propylamine, ethanolamine, diethanolamine, triethanolamine, methyl ethanolamine (MEA), ethyl ethanolamine, methyl diethanolamine, ethyl diethanolamine, dimethyl ethanolamine, diethyl ethanolamine, morpholine, N-methylmorpholine, N-ethylmorpholine and/or N-propylmorpholine.Preferred Additives: The composition further comprises solvent consisting of water, at least one oxygenate consisting of 1-6C alcohols, 2-6C glycols, 1-6C mono-alkyl ethers of 2-6C glycol, glycerin, 1-6C mono-alkyl ethers of glycerin, 3-6C dialkyl ethers of glycerin, glycerin esters of 1-6C carboxylate and/or 3-10C ketones.Preferred Composition: The composition comprises (vol.%) onium compound (5-75) and amine salt (10-95). It may also comprise solvent (0-85). EXAMPLE - A composition comprised of 0.030 units of RE 4136 (quaternary ammonium compound, Baker Petrolite), 0.03 ml of methanol, 0.24 ml of MEA acetate and 7.5 vol.% of additive/water was introduced into a high pressure stainless cell with glass windows. The volume of the cell was 35 ml including all the ancillary plumbing. A mixed hydrocarbon gas was introduced into the cell and shaken to dissolve the gas. More gas was introduced and the process was repeated until equilibrium gas pressure was reached. The cell was then placed in a temperature-controlled and cooled water bath for 23 +/- 1 hours. The cell was examined, rocked for 5 minutes and was re-examined, and then rocked for another 25 minutes (total of 30 minutes) and again re-examined. During the 23 hours and 5 minutes, there were no visible crystals, no solid deposits on glass or steel, and only two distinct liquid phases were observed. After the 30 minutes, no evidence of plugs was found in the system.
