Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 90-64-2, Name is 2-Hydroxy-2-phenylacetic acid, molecular formula is C8H8O3, belongs to phthalazines compound, is a common compound. In a patnet, author is Zhao, Shanshan, once mentioned the new application about 90-64-2, HPLC of Formula: C8H8O3.
Recycling of high temperature steam condensed water from petroleum refinery by thermostable PPESK ultrafiltration membrane
The purification and reclaiming of synthetic and industrial high temperature condensed water containing excess oil and iron is investigated in this study using thermostable poly(phthalazine ether sulfone ketone) (PPESK) ultrafiltration membranes. The results show operation parameters such as transmembrane pressure, temperature and pH of feed solution, initial oil and iron concentration each play important roles in the permeate flux and oil/iron removal efficiencies. Membrane performance is almost recovered after washing with a combination of NaOH and ethanol. High temperature condensed water from Daqing petroleum refinery can be consecutively purified using a PPESK ultrafiltration membrane. The turbidity of the solutions is almost removed. Oil and iron concentrations in the permeate solutions are below 1 mg/L and 50 mu g/L, respectively, which satisfy the Quality Criterion of Water and Steam for Steam Power Equipment in China. UF process shows a promising alternative to existing technology in the Daqing petroleum refinery in terms of cost and environmental protection as well as energy recovery. For future possible combination of UF and NF process application, both economic cost and saving are evaluated, and the breakeven time is about 11 months. (C) 2013 Elsevier B.V. All rights reserved.
