Service conditions:

Temperature: 20～60°C

Airspeed: 500 to 1500 hours - 1,500 to 1,000 hours - 1 is appropriate.

Pressure: normal pressure to 8.0Mpa

Ratio of height to diameter: 3:1

Water content and pH:
The water in desulfurizer plays a role as the medium, and the amount should be: 10% or less is appropriate. For usage, a small amount of water vapor is required in the gas, in order to inhibit the air flow which will take away the water in desulfurizer, but not a lot of water vapor to prevent their condensation in the bed which may cause plugging of micro holes. pH 8-9, This product is a chemical adsorption desulfurizer, with the different order of contact with the gas flow, the amount of sulfur absorption is also inconsistent. In order to make the desulfurizer to achieve higher utilization, it is best to set 2-3 desulfurization tower in series. The desulfurizer in the first tower is firstly deactivated, and update the desulfurizer in the first tower, so the gas is passed in the order of 2—3—1, and then replace the desulfurizer in the second tower; the gas is passed in the order of 3—1—2, so that the maximum adsorption value of desulfurization can be achieved.
The dosage of desulfurizer is determined by the following conditions:
1. H2S concentration and gas flow in feed gas

2. Requirements value of the H2S concentration in desulfurization tower outlet
3. Replacement cycle of desulfurizer

Normal packaging

1. Woven bag lined with plastic bag: 40kg/bag

2. Bags for tons of materials: 800-900kg/bag

Other Package

If the customer requires the product delivered in cartons, plastic barrels, drums and other containers, extra fee will be charged.

Transport and Storage

1. Transportation

It shall not be transported along with hard materials to reduce vibration and friction and hence to reduce the impact on use brought by smashing;

2. Storage

It shall be stored in a cool, dark and dry place, and protected from being in direct contact with the outside and absorbing other materials due to the inside or outside breakage of the package, which otherwise lowers its capability of absorbing hydrogen sulfide, affecting its effect in use;

3. No blisters

This product is a porous adsorbent, and water immersion is strictly forbidden during transportation, storage and use because it will fail to work when a large mass of water fills its active pores.

4. Preventing materials in the tar category

Materials in the tar category shall be prevented from entering the bed layer for the desulfurizer in production and operation in case it may not work normally.

Precautions for loading and employing large and medium-sized desulfurization towers:

1. Before loaded, the desulfurization tower must be cleaned up with the load of each layer defined. Two loading layers or more are preferred;

2. In the process of loading, a layer of steel wire mesh and refractory balls shall first be laid on the wallboard of the furnace, followed by two layers of stainless steel wire mesh of some 20 meshes. After that the desulfurizer shall be filled;

3. The desulfurizer shall be poured into the furnace gently from the height as low as possible with the free-fall height of the particles less than 0.5 m;

4. During loading, the catalyst shall be scattered and evenly placed, and centralized pouring or pouring only from one side is not allowed in order to avoid the occurrence of uneven loading and deviated gas flow accordingly;

5. Operators shall stand on a wooden board and load the tower. It is strictly forbidden to stamp directly on the catalyst to prevent producing new powder;

6. The well-laid catalyst shall be flattened with a wooden board, and then covered with a layer of iron mesh and refractory balls;

7. A proper amount of water vapor may exist in the raw material gas, but a great amount of water or gathered water shall not be found on the bed layer. The condensation water in front of the tower, and the sewage at the bottom of the tower shall be regularly discharged;

8. The sequence of the gas passing the towers shall be considered while a couple of towers are operated, to keep the working desulfurizer as saturated with sulfur as possible;

9. The bottom valve of the desulfurization tower is used for discharging water. Gathered water shall be discharged.
