Advanced purification and comprehensive utilization of yellow phosphorous off gas

Ping NING,Xiangyu WANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2,   Pages 181-189 doi: 10.1007/s11783-014-0698-1

Abstract: Yellow phosphorous is an important raw material in the chemical industry. However, during the production of yellow phosphorous, high concentrations of carbon monoxide and other impurities are released. Without appropriate purification and removal, this off gas has potential to cause severe pollution problems once released. Purified yellow phosphorous off gas can be beneficially reused as a raw material in chemical production for synthesis of high value-added chemical reagents. In this paper, the significance of purification and reutilization of yellow phosphorous off gas are explored. The principles, processes, and main characteristics of the technologies for purification and reuse of yellow phosphorus off gas (including technical measurements of impurity reduction, relevant engineering cases, and public acceptance of the technologies) are summarized. In view of the existing problems and scientific development requirements, this paper proposes several recommendations for green production based on the concept of recycle economics. We conclude that advanced purification and comprehensive reutilization can be an effective solution for heavy pollution resulting from yellow phosphorous off gassing.

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2,   Pages 224-228 doi: 10.1007/s11705-009-0067-y

Abstract: The reactions of CO with oxirane to produce cyclic carbonate, and with aziridine to afford oxazolidine have been of interest as a useful method for its fixation by a chemical process. Highly efficient processesemploying recyclable CO -phlilic homogeneous catalyst were devised for environmentally benign synthesis of cyclic carbonates and oxazolidinones under supercritical CO without any organic solvent. These processes represent pathways for greener chemical fixations of CO to afford industrial useful materials such as organic carbonates and oxazolidinones with great potential applications.

Industrial waste utilization method: producing poly-ferric sulfate (PFS) from sodium-jarosite residue

Zhongguo LI,Wenyi YUAN

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 4,   Pages 731-737 doi: 10.1007/s11783-014-0687-4

Abstract: Sodium-jarosite is a type of industrial waste that results from hydrometallurgy and inorganic chemical production. The iron content of jarosite residue may be utilized to produce theoretically the ferrous materials. The difficulty in production of high quality poly-ferric sulfate (PFS) is how to remove impurities contained in jarosite residue. This paper proposes a novel method for disposing sodium-jarosite which can be used to synthesize PFS, a very important reagent for treating waste water. The method consists of a two-step leaching experimental procedures. The first step, pre-leaching process, is to remove impurity metals by strictly controlling the leaching conditions. The acid concentration of acidic water was adjusted according to the content of impurity metals in sodium-jarosite and the leaching temperature was controlled at 25°C. The second step is to decompose sodium-jarosite to provide enough ferric ions for synthesizing PFS, the concentrated sulfuric acid consumption was 0.8 mL·g sodium-jarosite and the leaching temperature was above 60°C. In the experiment, decomposing iron from sulfate sodium-jarosite can take the place of ferric martials for synthesizing PFS. Results show that the PFS synthesized from sodium-jarosite had a high poly-iron complex Fe (SO ) (OH) ·20H O. Further, the PFS product’s specifications satisfied the national standard of China.
