Cracked gasoline antioxidant STD-3B

Cracked gasoline antioxidant STD-3B can effectively prevent the oxidation and polymerization of unsaturated hydrocarbons in cracked gasoline, prevent the production of colloids, and improve the stability of cracked gasoline. This additive has good thermal stability and strong water resistance. It dissolves in aromatic and aliphatic hydrocarbons and does not contain halogens and heavy metal elements.

Properties

This additive appears as a colorless or light yellow oily liquid, is alkaline, and is irritating and corrosive to the human body.

Uses

This additive is mainly used for the anti-oxidation of cracked gasoline in ethylene plants and the anti-oxidation of liquid fuel oil in refineries to improve the stability of oil.

Precautions

1. This additive has a swelling effect on high molecular materials such as chloroprene rubber and polyvinyl chloride;

2. When used on the production site, the general addition concentration is 20~50rg/g (based on the product). You can add 50

μg/g first, and then gradually reduce it to 30μg/g after running for several days, observe the effect, decide to increase or decrease, and determine the best addition amount;

3. The addition location needs to be based on the system’s anti-oxidation requirements to ensure that the additive and process medium are fully mixed when entering the equipment;

4. This additive can be added to the system evenly and continuously using a plunger metering pump. It can also be diluted to a certain concentration with a solvent as needed before use.
