In petroleum refineries, the elec. desalting, distillation, and stripping processes could generate large amounts of wastewaters that contain toxic substances. In this study, eight wastewater samples were collected from the three typical refining processes for comprehensive chem. characterization of the dissolved organic matter (DOM) using excitation emission matrix fluorescence spectroscopy, gas chromatog.-mass spectrometry, and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Results showed that protein-like components and benzene were ubiquitous in all these wastewaters. Oxygen-containing volatile organic compounds had higher contents in crude distillation and stripping wastewater than those in elec. desalting wastewater. Among the three refinery processes, mol. composition of DOM in the stripping wastewater had the highest complexity. The Ox and OxSy class species assigned from the neg.-ion electrospray ionization FT-ICR MS were dominant in all wastewaters. The OxS2 class species which were effectively removed during stripping treatment had highest relative abundance in stripping influent. These results are instructive to guide the development of ”divide and conquer” and would improve the treatment and management of refinery wastewater streams. In the experiment, the researchers used many compounds, for example, 4-Methyl-1H-indole (cas: 16096-32-5HPLC of Formula: 16096-32-5).
4-Methyl-1H-indole (cas: 16096-32-5) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.HPLC of Formula: 16096-32-5
