络合铁脱硫优势
Desulfurization advantages of complex iron
（1）络合铁催化剂，工艺处理过程简单，采用一步法处理工艺即可快速将硫化氢直接氧化为硫单质；对各种不同浓度的H2S，其脱硫后的H2S含量可低于10ppm，清除H2S效率高。
(1) The complex iron catalyst has a simple process, and hydrogen sulfide can be directly oxidized to sulfur by one-step process; For various concentrations of H2S, the H2S content after desulfurization can be lower than 10ppm, and the H2S removal efficiency is high.
（2）系统的抗波动能力强。对于传统的脱硫装置，原料气中硫化氢含量波动较大时，会造成出口净化气的硫化氢含量波动很大，甚至超标。络合铁高硫容特性，其脱硫装置完全能自动处理以上波动情况，并不需要人为改变操作且不会影响脱硫率。
(2) The system has strong anti-fluctuation ability. For the traditional desulfurization unit, when the content of hydrogen sulfide in the feed gas fluctuates greatly, the content of hydrogen sulfide in the outlet purified gas will fluctuate greatly, even exceed the standard. Due to the high sulfur capacity of complex iron, its desulfurization device can completely deal with the above fluctuations automatically, and does not need to change the operation manually and will not affect the desulfurization rate.
（3）运行成本低。由于在脱硫过程中所使用的各种药剂中的络合铁催化剂可再生循环使用且无副反应发生，只需补充少量的在脱硫过程中损失的络合铁催化剂，产出一吨硫磺药剂运行成本1000-1500元。
(3) Low operating cost. As the complex iron catalyst used in various reagents used in the desulfurization process is renewable and recyclable without side reaction, only a small amount of complex iron catalyst lost in the desulfurization process needs to be supplemented, and the operating cost of one ton of sulfur reagent is 1000-1500 yuan.
（4）络合铁催化剂选择性高，副盐产生量低。在络合铁脱硫中，络合铁离子氧化硫化氢为硫磺，脱硫过程副反应少，药剂使用寿命长。
(4) The complex iron catalyst has high selectivity and low bysalt production. In complex iron desulfurization, complex iron ions oxidize hydrogen sulfide to sulfur, resulting in fewer side reactions and long service life of the reagent.
（5）脱硫工作液硫容量高。新开发的络合铁脱硫剂，脱硫剂循环液的硫容量不受二氧化碳的影响，其工作硫容量高达3.3kg硫磺/m药剂，高于国外同类技术（工作硫容量较好的为0.37 kg硫磺/m药剂）。故使用络合铁脱硫剂能显著降低循环液量，降低设备尺寸，减少投资和操作成本。
(5) The desulfurization working fluid has high sulfur capacity. The newly developed complex iron desulfurizer, the sulfur capacity of desulfurizer circulating liquid is not affected by carbon dioxide, and its working sulfur capacity is up to 3.3kg sulfur/m reagent, which is higher than that of similar foreign technologies (0.37 kg sulfur/m reagent with better working sulfur capacity). Therefore, the use of complex iron desulfurizer can significantly reduce the amount of circulating liquid, reduce the size of equipment, and reduce investment and operating costs.
（6）能脱除有机硫COS、硫醇。
(6) It can remove organic sulfur COS and mercaptan.
（7）设备尺寸小，可有效实现橇装化。由于工作硫容量高，设备小，可有效实现橇装化，非常适合小项目的橇装化要求。
(7) The equipment is small in size and can be effectively skid-mounted. Due to high working sulfur capacity and small equipment, skid-mounted equipment can be effectively realized, which is very suitable for skid-mounted requirements of small projects.
（8）催化剂的安全性高，系统所采用的催化剂对环境及人体无毒无害，具有良好的环保效益。
(8) The catalyst has high safety. The catalyst used in the system is non-toxic and harmless to the environment and human body, and has good environmental benefits.
