Description
Two proposed sample preparation method were applied for the gas chromatographic analysis of sulfur compounds and aliphatic amines in the exhaust gas from a fish meal dryer and cooker.<BR>At least eleven sulfur compounds from a fish meal dryer and at least seven sulfur compounds from a cooker were identified including hydrogen sulfide and methylmercaptan by the use of direct cold trap method with liquid oxygen, and by flame photometric detector.<BR>The detected concentrations of representative sulfur compounds in the exhaust gas from the fish meal dryer are as follows; carbonyl sulfide 0.08ppm, hydrogen sulfide 0.91ppm, carbon disulfide 0.03ppm, methylmercaptan 0.32ppm, n-propyl mercaptan 0.40ppm, dimethyl disulfide 0.17ppm.<BR>From the cooker; carbonyl sulfide 0.03ppm, hydrogen sulfide 4.2ppm, carbon disulfide 0.02ppm, methyl mercaptan 5.2ppm, and dimethyl disulfide 0.09ppm were detected.<BR>The major component of the exhaust gas from the fish meal dryer was hydrogen sulfide, and that from the cooker was methyl mercaptan.<BR>From analysis of aliphatic amines, only trimethyl amine was detected by the use of direct cold trap method with liquid oxygen and chemical trap method with 0.1 N-hydrochloric acid aqueous solution, and by flame ionization detector.<BR>In latter case the trapped sample was decomposed with 40% sodium hydroxide aqueous solution, followed by the cold trap method.<BR>The detected concentrations of trimethylamine are as follows; 0.42ppm, for the exhaust gas from fish meal dryer and 1.0ppm for the exhaust gas from cooker.<BR>In this method of analysis, a 5.8ppm of ethanol was also detected.<BR>The concentrations ratio of trimethylamine versus hydrogen sulfide in fish meal dryer was about 0.5 : 1, and in cooker about 0.2 : 1.
