Gasoline hydrogenation anti-oxidation inhibitor STD-38
STD-38 gasoline hydrogenation anti-oxidation inhibitor has the functions of anti-oxidation, anti-polymerization, cleaning and dispersing, and can effectively inhibit the scaling and oxidation of C and C products in the process of pyrolysis gasoline hydrogenation. The additive has strong thermal stability and good water resistance. It is soluble in aromatic and aliphatic hydrocarbon solvents and does not contain halogens and heavy metal elements.
Properties
This additive is a red oily liquid, alkaline, and irritating to the human body.
Uses
STD-38 can be used for anti-polymerization and anti-scaling of the de-C5 tower and hydrogenation reactor of the pyrolysis gasoline hydrogenation unit. It can also be used for anti-oxidation and anti-polymerization of pyrolysis gasoline.
Precautions
1. Injection concentration: In industrial applications, the general injection concentration is 40~80μg/g of the material flow at the injection point (based on the original additive solution). You can first inject 80pg/g, run for several days, and then gradually reduce it to 60mg/g, observe the effect, decide to increase or decrease, and determine the optimal injection concentration.
2. Injection point: The recommended injection site is the release line of the debutanizer tower kettle liquid (or the feed line of the C5 tower) and the gas phase extraction line at the top of the tower (to be determined according to the actual situation of the specific user).
Packaging
This additive is packaged in plastic barrels with a net weight of 160 ± 0.5 kg.
Safety protection
Store in a cool and low temperature place, avoid contact with fire or heat sources. In case of fire, use dry powder or carbon dioxide fire extinguisher to extinguish the fire.
