Research on characteristics of composition and sedimentation separation of high calcium-type ASP produced water was written by Zhang, Jie;Hu, Hai-bing;Wei, Li;Li, Chun-ying;Yu, Gang. And the article was included in Harbin Shangye Daxue Xuebao, Ziran Kexueban in 2014.Formula: C18H37Cl This article mentions the following:
ASP-flooding is a new kind of flooding technol. The produced water reinjection is an important issue restricting the tech. promotion. Three-dimensional fluorescence spectra and GC-MS were applied for the research. The composition of organic and oil/water separation characteristics were studied. Results indicated that much more calcium ions and silicium ions could be detected in the high calcium-type ASP produced water. The value of BOD/COD was 0.1654. It had bad biodegradability, belonging to moderate salt industrial waste water. The kinds of main organic matters were 78. The extraction agent of Me tert-Bu ether was primarily hydrocarbons and alkanes. The extraction agent of n-hexane was a toxic matter, such as benzene series and naphthaline. After phys. sedimentation, the oil removal rate was 81.34%, and the suspended solids removal rate was 85.45%. The speed of oil-water separation was slow. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Formula: C18H37Cl).
1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C18H37Cl
