A, product features and uses

LYT 310C is activated Zinc Oxide as main ingredients, new high efficientdesulfurizer used at ambient temperature with addition of appropriate amount ofadditive preparation, suitable for synthesis gas, natural gas, oil and gas, convertergas, hydrogen and nitrogen gas, liquid hydrocarbon, liquefied petroleum gas andfood grade CO2 of sulfur removal. LYT 310C Zinc Oxide desulfurizer has the characteristics of sulfur capacity, high strength, good water resistance, and strong adaptability, use at 20 ℃ -120 ℃.

Two, product quality index

Three, the normal application process conditions

1 gas content of H2S is less than 100ppm is appropriate.

The 2 pressure: pressure ~ 8.0MPa

3: temperature 20 ~ 120 ℃

4 gas space velocity 1000 ~ 3000h-1

5 liquid space velocity 1 ~ 5H-1

6 oxygen content in feed gas should not be greater than 0.5%

7 bed / tower diameter: 3

Four, desulfurization agent loading

1 first in the upper plate of the desulfurizing tower two layer 10 ~ 20 mesh stainless steel wire mesh.

2 in the screen with a height of 100 mm, 20 mm to 30 mm ceramic ball or porcelain ring.

3 check the desulfurizer, consider whether you need sieving.

4 with a special tool, the desulfurization agent uniformly filled to the inside of the tower, should check whether smooth, uniform loading; such as the need to enter the tower work, must first lay on board on the catalyst, stepped on to work on board.

5 sorbent surface should be porcelain ball or a ceramic ring is covered with a layer of 10 ~ 20 mesh stainless steel wire mesh and 50 mm thick, 20 mm to 30 mm, in order to prevent the air blowing desulfurization agent, and the uniform airflowdistribution.

Five, drive

1 with nitrogen or other inert gas replacement system, when less than 0.5% ofoxygen content in gas, that the

For qualified.

The 2 step, every 30 minutes until it reaches 0.5MPa, operating pressure.

3 replacement of qualified, spent 4 hours half load operation, to adjust thetemperature, pressure, flow, the operation is stable, and gradually increase theload, into normal production.

Six, parking

1 temporary parking

Cut off the gas source, close, outlet valve, heat, pressure, preventing the systempressure.

2 replace desulfurizer

Raw materials used in air or nitrogen gas cooling, buck, the system under normal temperature and pressure, the desulfurization tower and production systemisolation, and then open the desulfurization tower discharging catalyst.

3 equipment maintenance parking procedures ibid.

4 remove the desulfurizing agent the best hierarchical storage, each layer of therepresentative samples of the sulfur capacity, according to the analysis results,whether continue to use and duration of use.

Seven, packaging and storage

1, desulfurization agent for paperboard barrel lined with plastic bag, packing,prevent moisture absorption and chemical pollution..

Avoid scrolling should be 2, in the process of transportation, collision and vibration,so as to avoid crushing.

3, good packaging products should be stored in dry warehouse, can not be in contact with other chemicals, to prevent pollution, damp and broken.

4, no damage on the packaging, storage of 3-5 years normal use.
