Sweetening agent for ironicoxide Industrial Grade

ZDE - 01 type iron oxide desulfurizer at normal temperature specification

ZDE - 01 type normal temperature ferric oxide desulfurizer Fe2O3 is activity as the main component, and add a variety of additives.

ZDE - 01 type desulfurizer good adaptability is a kind of new type high efficiency dry gas desulfurization agent at room temperature, can work under the condition of atmospheric pressure or pressure. Use with simple equipment, easy operation, large sulfur capacity, purifying degree is high, strong adaptability, etc. Widely used in natural gas, natural gas, coal gas, coke oven gas desulfurization, CNG gas, shift gas, food, carbon dioxide, carbon dioxide gas, petroleum refining, gas, methane and other gases removal of H2S in removal of organic sulfur also to have certain ZDE series products are the best quality products, the current domestic market for a long time by the new and old customers of all ages.

A, the main physical and chemical properties

Shape and size: phi (4.5 ~ 5.5) x (5 ~ 15) mm, exterior color to red (yellow), brown garden bar strips.

Bulk density: 0.8 ~ 0.9 kg/l.

Hole: ~ 0.4 ml/g

Sex: under the condition of normal use desulfurization precision can reach 1 under the MGS/Nm3.

Second, the technical indicators

Lateral pressure crushing strength: 35 Newton or/cm.

The sulfur capacity of work: 35% or higher

Third, desulfurization regeneration reaction principle

1, the desulfurization

Fe2O3 · H2O + 3 h2s = Fe2S3 · H2O + 3 H2 O + 5.2 kilocalorie

2, regeneration

2 fe2s3 O2 · H2O + 3 = = 2 fe2o3 · H2O + 6 s + 94.2 kilocalorie

Regeneration is a strong exothermic reaction.

If gas containing O2, when O2 / H2S > 2.5, desulfurization regeneration can realize continuous regeneration, the above equation into:

Fe2O3 · H2O

2 h2s + O2 = = = = = = = = = = = = = = 2 h2o + 2 s

Iron oxide catalyst effectively.

Four, the operation conditions of use

Temperature: room temperature, with 20 ~ 40 ℃ advisable.

Speed: (1) atmospheric: 200 ~ 500 hours - 1

(2) pressure: 500-1 ~ 1000 hours

Pressure force: atmospheric pressure to 3 mpa

High aspect ratio: 3 above

Gas purification: containing H2S allow up to 5000 the MGS/Nm3, if you want high desulfurization precision can use multilevel desulfurization.

Water content, water plays a role of media in the process of desulfurization, feed gas dry wet and will affect the desulfurization efficiency. Requirements in the gas water vapor content to no more than operating temperature under the condition of saturation is advisable. It is forbidden to process feed gas liquid, jam desulfurizer microporous and severe damage to its strength.

PH: keep the desulfurizer PH8 ~ 9, good for desulfurization.

Born again: temperature: 30 ~ 60 ℃, the highest must not exceed 80 ℃

Five, the desulfurizer used

1, equipment,

Desulfurization tower height and diameter should be greater than 3.0 in place to ensure that the appropriate line speed, desulfurization bed is generally divided into two layers. In order to improve the utilization rate of desulfurizer, desulfurization tower should configure two commonly. Valve and pipeline configuration should be convenient to switch series, in parallel operation.

2, packing method,

(1) loading before sieving to dust: desulfurization tower are not allowed to have residual waste desulfurizer dust. Loading does not allow more than 0.5 m free fall, more do not allow the people trampled on desulfurizer, man must be loading into the furnace, should be on the desulfurizer cushion board.

(2) of the desulfurization tower grew board laid a layer of phi 15 ~ 20 mm ~ 80 mm ceramic ball, ceramic ball placed on the second floor is less than 4 mm mesh wire mesh, the desulfurizer, after loading, desulfurizer to put a layer of wire mesh, with porcelain ball pressure on it, also the blow gas desulfurizer.

3, driving program

(1) the desulfurizer dust purging and system and the displacement

Blow gas may be air or gas material. If need air feed gas exchange system, after waiting for gas exports the same as the imported ingredients that qualified replacement.

(2) the booster

In a pressurized system should be gradually booster, booster 0.1 MPa, every 2 minutes until operating pressure is reached. After the booster, 1 ~ 2 hours and a half load advanced production, such as pressure and flow adjustment. For stable operation and then gradually increase the load, turn into normal production.

(3)

H2S in desulfurization DaChu tone exceeds bid, the boiler stop for regeneration.

Regeneration steps:

(1) to cut off the raw material gas, close the inlet valve, according to every 2 minutes to reduce the speed of 0.1 MPa pressure gradually to pressure drop to normal pressure tower, finally close the outlet valve separate desulfurization tower, from the production system.

(2) open the vent valve tower top.

(3) to open the bottom into the orifice (or turn on the regeneration of intake valve), under the condition of natural ventilation, desulfurizer slowly regenerate, in order to speed up the regeneration, compressed air is piped in, but to control temperature, no greater than 60 ℃, the highest must not exceed 80 ℃, otherwise will produce sulfur sublimation and spontaneous combustion, causes the damage of desulfurizer and its equipment. The standard for the regeneration of the end of the bed temperature does not rise, the import and export of oxygen content is basic same, as end of regeneration.

(4) parking

Temporary parking: close the inlet valve, outlet valve, pressure maintaining. If the system leakage, must use the raw material gas pressure, to prevent negative pressure system.

Replace the desulfurizer parking: according to regeneration steps for processing. And then discharged.

Six, matters needing attention

1, new desulfurizer strength is low, to should take put down gently, in high desulfurization tower layered packing, each layer with 2 ~ 3 meters advisable; Conduct in the use of avoid by all means, booster, otherwise, stress will make desulfurizer powder; Forbidden desulfurizer bubble water, because it will lead to the strength of the great damage.

2, desulfurization tower should be set at least two temperature measuring points, facilitate the regeneration temperature of observation, once there were signs of overtemperature shall shall adopt measures to avoid the damage of desulfurizer and its equipment.

3, desulfurization agent can be a full replacement, according to specific situation can be replaced by stratified airflow direction.

Seven, packaging and storage and transportation

1, the desulfurizer with composite woven bags lined with plastic bag in order to prevent the leakage, moisture absorption and chemical pollution.

2, transportation and handling should be avoided in the process of rolling, impact pressure and severe vibration and swing, step, so as to avoid pulverization.

3, storage and transportation should be waterproof, moistureproof.

When 4, this product is a non-dangerous goods, storage and transportation in accordance with the relevant provisions.

Eight, technical advice and services

ZDE - 01 type desulfurizer wide scope of application, different conditions, to ensure that users get satisfied effect, will be responsible for pre-sales, after-sales service, assist in developing desulfurization solutions and help to solve out the problems in the operation.

Nine, the product is the standard of Q / 76509964-7.01-2008.
