主要研究了工业生产过程中,乙烷含量对乙烯环氧化性能的影响。结果表明:在装置负荷基本稳定条件下,当循环气内乙烷含量短时间波动时,银催化剂氯平衡被打破,反应活性、选择性和反应器出口环氧乙烷(EO)浓度均受到影响。同时,循环气内氯组... 主要研究了工业生产过程中,乙烷含量对乙烯环氧化性能的影响。结果表明:在装置负荷基本稳定条件下,当循环气内乙烷含量短时间波动时,银催化剂氯平衡被打破,反应活性、选择性和反应器出口环氧乙烷(EO)浓度均受到影响。同时,循环气内氯组成会发生变化。其中,氯乙烷、总氯的含量和CC因子变化趋势与乙烷含量波动趋势基本保持一致,但是CC因子变化程度小于总氯。 展开更多

After conducting a lot of screening experiments the appropriate flocculating formulations for treating high-concentration wastewater discharged from a certain refinery were selected. The oil removal rate and COD removal achieved by these flocculating formulations were better than that achieved by the conventional compound formulation consisting of polyaluminium chloride(PAC) and polyacrylamide(PAA) . Addition of an oil/water separating agent to the formulation could improve its oil removal performance to facilitate the oil/water separation of the oil-in-water emulsion in the high-concentration wastewater along with improved adaptability of the formulation to the wastewater containing high concentration of pollutants. This flocculating agent has promising prospects for commercial application. 展开更多
