1. The amount of desulfurization liquid in the system is the most critical data affecting the investment and use effect. If the measured quantity is less than the actual quantity, although the investment estimation is low, the first dosage concentration determined according to the scheme can not meet the requirements, affecting the use effect. Therefore, the total amount of desulfurization liquid in the system should be estimated accurately to ensure the initial concentration of catalyst

2、催化剂应避光、防潮储存，储存环境温度不宜过高，正常环境储存质保期为 2年。

2. The catalyst shall be stored away from light and moisture. The storage ambient temperature shall not be too high. The warranty period for normal storage is 2 years.

3、应用后注意监测脱硫液碱度和硫泡沫的分离情况，因硫容高系统硫磺产量会增加，需要关注熔硫釜的处理能力。

3. After application, attention should be paid to monitoring the separation of desulphurizing liquid alkalinity and sulfur foam. Because sulfur content in high sulfur system will increase, the treatment capacity of sulfur melting kettle should be paid attention to.

4、络合铁脱硫催化剂在脱硫液中理论上是不消耗的， 但由于在生产过程中催化剂会随着硫泡沫带出或溶液损失造成的流失是难以避免的，所以应定期向脱硫液中补充适量的浓缩脱硫催化剂，以维持脱硫液中正常的催化剂浓度.

4. The complex iron desulphurizing catalyst is not consumed theoretically in the desulphurizing liquid. However, because the loss of the catalyst will lead to the loss of sulphur foam or the loss of solution, it is difficult to avoid the desulphurizing solution. Therefore, regular desulfurization catalyst should be regularly added to the desulfurization solution to maintain the normal catalyst concentration in the desulfurization solution.

5、若脱硫负荷超过设计能力太多时，要适当提高吸收剂及催化剂的浓度。

5. If the desulfurization load exceeds the design capacity too much, appropriately increase the concentration of absorbent and catalyst.

6、络合铁催化剂虽然有抗油干扰的能力，但是大量焦油、洗油带入脱硫液而影响脱硫系统的硫泡沫形成，因此要做好入脱硫系统煤气的预处理工作。

6. Although the complex iron catalyst has the ability to resist oil interference, a large amount of tar and washing oil will bring into the desulfurization solution and affect the formation of sulfur foam in the desulfurization system. Therefore, the pretreatment of the gas into the desulfurization system should be well done.
