Speed desulfurizer
Desulfurizer is a new type of desulfurization agent, which is made from the N-methyl-diethanolamine as the main body and is equipped with a certain proportion of active agent, defoamer, stabilizer, corrosion inhibitor, antioxidant and other additives.
Product features and uses
Compared with single-component desulfurization agent, it has outstanding advantages.
1. It has high desulfurization efficiency, and the desulfurization rate won’t decline in the case of half catalyst oil. It has good H2S removal selectivity in the presence of both CO2 and H2S, which could completely remove inorganic sulfur, and partially remove organic sulfur compounds such as mercaptan thus enable the H2S and total sulfur content up to several PPm to meet the application requirements.
2. High chemical stability, non-degradable, sulfur high capacity and easy regeneration of desulfurization solution.
3. Small reaction heat, low desorption temperature, less energy consumption and with significant economic benefits.
4. Hard to foam with less loss.
5. Non-corrosive, can prolong the equipment service life.
The desulfurization agent is easy to use, with little amount, which is widely used in removal of H2S, SO2, COS in refinery FCC dry gas, liquefied petroleum gas, natural gas, refinery gas, Claus plant tail gas, city gas and other acid gases.

Using methods
The desulfurization agent is soluble in water, non-toxic odorless, easy to operate, safe and reliable, without any transformation of the original desulfurization equipment, use the desulfurization agent by the same method. Prior to the changeover to the desulfurization agent, there is no need to removal the original agents in the device, just add the agent, make replacement step by step, which does not affect normal production.
Packaging, storage, transportation
1. The product is packed with galvanized iron drum with the net mass of 200kg.
2. The product should be stored in a cool, ventilated, dry warehouse, with 1 year’s shelf-life period.
3. The goods transportation should be handled with care and not upside down; avoid sun and rain

SiC | Deoxidizer of carbon steel, silicon steel and cast iron | 1. Inexpensive high-quality silicon source, carbon source. 2. The ductile iron smelting has the following effects: A. Strong deoxidation effect that can reduce the dosage nodulizer B. Prevent the precipitation of carbides and is conducive to increasing the amount of ferrite C. Increase the rate of ductile iron 3. Can extend the life of furnace for 30% 4. Can reduce the slag production to make slag operation simple 5. Can use rusty scraps and alloys, to reduce the cost of hot metal 6. Reduce white mouth, significantly improve the cutting performance and enhance mechanical properties 7. Increase the mobility to stabilize hot metal composition and to prevent segregation 8. Reduce wall thickness sensitivity to achieve dense organization and smooth cutting surface. 10. No need to worry the increase of sulfur in molten iron | 1. Low (high) frequency furnace (when producing cast iron) 1). After preheating initial dissolved iron, either directly or using a shovel to put into paper bags, and then add other materials 2. In continuous operation, put both the quantitative silicon carbide paper, either directly or using a shovel into molten iron, and then add the other materials. 3). SiC is made from excellent quality of silicon and carbon source, no need to add the silicon or carbon agent in this part. 4). In the above circumstances, calculate the silicon and carbon absorption rates according to 97%. 5). Add the appropriate amount of 0.6-1.0%. 2. L-type furnace (in producing steel) 1). After oxygen blowing, the most effective method is to blow into the molten steel 2). Directly added to the molten steel 3). Add when the steel come out and stir to make it response |
Low silicon cover agent | Covering agent of ductile cast iron rushing | Coverage agent with breeding effect (including 20%’s Si) | Add 0.5-1% on the Mg alloy surface in the groove to make slow reaction time after combining with molten iron; or in the case of no proper Mg treatment, use the blended coverage agent and Mg alloy can also make good absorption rate and control the reaction. |
Fe-Si | Si additive of iron and steel cast iron deoxidizer | The impurity content is extremely low | Can specify the use of large block Can specify the use of low A1 |
