Gasoline hydrogenation inhibitor STD-18
Gasoline hydrogenation inhibitor STD-18 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 dissolves in aromatic and aliphatic hydrocarbon solvents and does not contain halogens and heavy metal elements.
Properties
This additive appears as a red oily liquid, is weakly alkaline, and is irritating to the human body.
Uses
It is used for anti-polymerization and anti-scaling of the Cs removal tower and hydrogenation reactor of the pyrolysis gasoline hydrogenation unit, and 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 40~80mg/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 60g/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 de-Cs 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).
3. Injection method: The additive can be injected into the system evenly and continuously with a plunger metering pump, or it can be diluted with a solvent into a solution of a certain concentration as needed.
4. Evaluation method: The evaluation of the application effect of the additive is mainly based on the pressure difference of the de-Cs tower before and after the injection of the additive and the operation cycle of the reboiler, as well as the change of the pressure difference of the hydrogenation reactor.
Packaging
This additive is packaged in a plastic-lined iron barrel or plastic barrel with a net weight of 160kg.
Safety protection
Store in a cool and low temperature place to avoid contact with fire or heat sources. In case of fire, dry powder or carbon dioxide fire extinguisher can be used to extinguish the fire.
