As a raw gas for carburzing,it is necessary to desulphurize in the natural gas sufficiently. 所以作为渗碳用原料气必须对天然气充分脱硫。
S content in steel could be lower than 0.005% by desulphur ization intensely in EF and LF. 通过在EF和LF炉中深度脱硫;钢中硫含量可达0.;005%25以下;
As cement retarder, the effect of desulphurize ash and dregs coming from power plant using fuel oil (DADFO) was studied here. 研究了石油焦脱硫灰渣用作水泥缓凝剂对水泥性能的影响。
The effects of desulphurize ash containing more CaSO3 on the setting time of cement clinker with various content of C3A and C4AF were studied. 研究了亚硫酸钙含量较多的脱硫灰对C_3A和C_4AF含量不同的水泥熟料凝结时间的影响。研究结果表明:亚硫酸钙对C_4AF有缓凝作用,而对C_3A基本不具缓凝作用;
We carried out key environmental protection projects to desulphurize emissions from coal-fired power plants, treat urban sewage and dispose of waste safely. 实施燃煤电厂脱硫、城市污水处理、垃圾无害化处理等环保重点工程。
The waste water discharged from textile printing and dyeing enterprise has strong alkalinity,can be used to desulphurize smoke and vapour exhausted directly from coal burning boiler. 而纺织印染企业排出的工业污水呈强碱性,可直接用于锅炉烟气脱硫。
