絡(luò)合鐵脫硫優(yōu)勢
Desulfurization advantages of complex iron
（1）絡(luò)合鐵催化劑，工藝處理過程簡單，采用一步法處理工藝即可快速將硫化氫直接氧化為硫單質(zhì)；對各種不同濃度的H2S，其脫硫后的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）系統(tǒng)的抗波動能力強。對于傳統(tǒng)的脫硫裝置，原料氣中硫化氫含量波動較大時，會造成出口凈化氣的硫化氫含量波動很大，甚至超標(biāo)。絡(luò)合鐵高硫容特性，其脫硫裝置完全能自動處理以上波動情況，并不需要人為改變操作且不會影響脫硫率。
(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）運行成本低。由于在脫硫過程中所使用的各種藥劑中的絡(luò)合鐵催化劑可再生循環(huán)使用且無副反應(yīng)發(fā)生，只需補充少量的在脫硫過程中損失的絡(luò)合鐵催化劑，產(chǎn)出一噸硫磺藥劑運行成本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）絡(luò)合鐵催化劑選擇性高，副鹽產(chǎn)生量低。在絡(luò)合鐵脫硫中，絡(luò)合鐵離子氧化硫化氫為硫磺，脫硫過程副反應(yīng)少，藥劑使用壽命長。
(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）脫硫工作液硫容量高。新開發(fā)的絡(luò)合鐵脫硫劑，脫硫劑循環(huán)液的硫容量不受二氧化碳的影響，其工作硫容量高達(dá)3.3kg硫磺/m藥劑，高于國外同類技術(shù)（工作硫容量較好的為0.37 kg硫磺/m藥劑）。故使用絡(luò)合鐵脫硫劑能顯著降低循環(huán)液量，降低設(shè)備尺寸，減少投資和操作成本。
(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）能脫除有機硫COS、硫醇。
(6) It can remove organic sulfur COS and mercaptan.
（7）設(shè)備尺寸小，可有效實現(xiàn)橇裝化。由于工作硫容量高，設(shè)備小，可有效實現(xiàn)橇裝化，非常適合小項目的橇裝化要求。
(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）催化劑的安全性高，系統(tǒng)所采用的催化劑對環(huán)境及人體無毒無害，具有良好的環(huán)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.
