Liquefied gas desulfurizer

1、overview

LPG desulfurizer is a binary metal oxide desulfurizer at room temperature with zinc oxide as the main active component developed and produced by Jiangxi 863 Company.

Suitable for fine hydrogen sulfide removal of propylene, natural gas, syngas, refinery gas, naphtha, solvent oil and other gas and liquid materials.

The agent has the characteristics of high desulfurization accuracy at room temperature, long service life, good mechanical strength, does not affect the color of the material, etc., especially suitable for the refining of the above-mentioned raw materials.

4、Precautions

1, the product in the transportation, storage process, should keep the package intact, avoid contact with rain.

2, in the filling process, the operator should not directly trample on the desulfurizer. The charge should be even and flat.

3. Nitrogen should be purged before unloading the agent, and then an appropriate amount of water should be sprayed into the desulfurization tank to avoid the temperature rise caused by the sulfide in the air during the unloading process.
