用碱液洗涤

Compressed acetylene access to a clean series of towers, tower 2 clean washed by the oxidation of sodium hypochlorite solution to remove sulfur, phosphorus and other impurities, and then into the tower and 10% to 15% alkali solution and, after purification acetylene by the cooling device of the initial removal of the water saturation after the sperm of more than 98.5 purity acetylene synthesis process used to send VCM.

压缩后的乙炔进入串联的1号清净塔、2号清净塔，经次氯酸钠溶液洗涤氧化除去硫、磷等杂质后，再进人中和塔用10%～15%碱液中和，净化后的乙炔经预冷器初步除去饱和的水分后，纯度98.5%以上的精乙炔送VCM合成工序使用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
