絡合鐵脫硫

Desulfurization with complex iron

絡合鐵法脫硫技術是一種以絡合鐵為催化劑的濕式氧化脫除硫化氫的方法，其特點是直接將H2S轉變成元素S，絡合鐵工藝技術是一種工藝簡單、工作硫容高且環(huán)保的新型脫硫技術，克服了傳統(tǒng)脫硫工藝硫容量低、脫硫工藝復雜、副鹽生成率高、環(huán)境污染嚴重等弊端，處理硫磺回收裝置尾氣可使硫磺回收率達到99.99%。

Complex iron desulfurization technology is a method of removing hydrogen sulfide by wet oxidation using complex iron as catalyst, which is characterized by directly transforming H2S into elemental S. Complex iron desulfurization technology is a new desulfurization technology with simple process, high working sulfur capacity, environmental protection and non-toxic, which overcomes the disadvantages of traditional desulfurization process such as low sulfur capacity, complex desulfurization process, high by-product generation rate, and serious environmental pollution, The sulfur recovery rate can reach 99.99% by treating the tail gas of sulfur recovery unit.

絡合鐵脫硫技術是具有自主知識產權的絡合鐵脫硫化氫成套技術，相對于其它絡合鐵脫硫技術，具有硫容量高、可撬裝化、脫硫成本低、、運行穩(wěn)定性高、投資低、對COS、硫醇有機硫脫除率高等優(yōu)點。

Complex iron desulfurization technology is a complete set of complex iron hydrogen sulfide removal technology with independent intellectual property rights. Compared with other complex iron desulfurization technologies, it has the advantages of high sulfur capacity, skid-mountable, low desulfurization cost, energy saving, high operation stability, low investment, and high removal rate of COS and mercaptan organic sulfur.
沼氣脫硫

說明

explain

干法脫硫多用于硫化氫處理負荷小，或者對脫硫效果要求很高的工況。這時，干法脫硫多用于濕法脫硫或者生物脫硫之后，進一步脫硫。

Dry desulfurization is mostly used in the condition of low hydrogen sulfide treatment load or high desulfurization effect. At this time, dry desulfurization is mostly used for further desulfurization after wet desulfurization or biological desulfurization.

在制定脫硫效果時，建議根據(jù)后續(xù)設備(鍋爐或發(fā)電機)對硫化氫濃度的限制，以及沼氣與天然氣消耗量的比例，制定一個合理的脫除效果。我們通常建議終的硫化氫含量控制在25~100ppm。

When formulating the desulfurization effect, it is suggested to formulate a reasonable removal effect based on the limit of hydrogen sulfide concentration of subsequent equipment (boiler or generator) and the proportion of biogas and natural gas consumption. We usually recommend that the final hydrogen sulfide content be controlled at 25~100ppm.
